Later on, some genera were excluded from Astragalus. De Candolle (1802) segregated several species and established the genus Oxytropis DC. All species of Oxytropis are characterized by the presence of beak on keel petal which is absent in Astragalus. This important character along with other taxonomic characters such as flower structure and the indumentum are well known diagnostic characters which are used to separate the two related genera from each other. In Flora Orientalis (Boissier, 1872) and Bunge’s monographic work (1874), the genus was represented with eigth distinct species. Later on, the number of its species was gradually increased. In Flora Iranica (Vassilczenko, 1984) the total number of the species was exaggeratly increased to 40. The majority of the newly described taxa were based on a single specimen, but after the first manuscript prepared by Vassilczenko, in the appendix of the same publication, Rechinger added two additional appendices and described several more new species (Rechinger, 1984) This decision indicates the informal complexities of the genus for the Iranian territory. The first attempt for the revision of the genus in Iran was started by Ranjbar (1999). He tried to determine some collected specimens deposited at TARI, and reduced some species to synonymy or doubtful species. Finally, he concluded that the number of species were 32 and for which a diagnostic key along with some notes were presented (Ranjbar 1999). At the first glance, the author carefully checked the authentic specimens and the availability of collected materials at TARI, IRAN, TUH, FUMH (abbreviation based on Holmgren and Holmgren, 1996) and other provincial herbaria. Then, the author found isotypes belonging to two groups of materials. The first group was the specimens for which the herbarium numbers were the same as holotype specimens, such as: O. yezdii, O. iranica, O zangoulehensis and O. allenii. The second group was the specimens for which the herbarium numbers were not the same as holotypes, but this specimens with other number or without number belonging to the same botanical excursion conducted by the Iranian taxonomists accompanying with Rechinger, Aellen and etc. These created the big problems for the Iranian taxonomists. In these cases, the date of excursions, elevation of localities and other labels information were similar but with different herbarium numbers, because the duplicate materials have been separately numbered and deposited at the different herbaria (Iranshahr 2010). These confusing materilas were belonging to O. surmmandehi, O. azarbayejanica and O. allavae. Part of the materials of FUMH with good collections from Khorassan province and identification of some complexes of O. hypsophila Bunge by Barneby (1970) was very useful and interesting for this investigation. For the confirmation of the determined materials, the photo of the type specimens in Jstore Website (2012) was used. Whenever, I decided to identify the unknown materials, I was faced with several problems such as: 1. It was not possible to identify the unknown specimens either with Flora Iranica (Vassilczenko 1984) or Ranjbar’s treatment (1999). 2. After appearance of Flora Iranica (Vassilczenko 1984), some other new species were described for the Iranian territory (Vassilczeko 1988; Ranjbar, 1999, 2008, Naqinezhad et al. 2008). 3. In the treatment of Flora Iranica, several new species have been shortly described probably based on a single and poor material in young stage. 4. There were several specific names in both treatments (Vassilczenko 1984, Ranjbar 1999), for which, no 3 Oxytropis in Iran specimens are available in four above mentioned herbaria or other provincial herbaria of Iran. 5. Based on long-standing studies on Astragalus (Maassoumi 1986, 1989, 1995, 2000, 2003, 2005) the author felt that several specific names of Oxytropis without flowering material might belong to Astragalus species. 6. For these reasons, the author precisely checked all specimens and tried to find some traces to Astragalus species. For several species, it seems that there is the big disjunction within the phytogeographical regions. Several species showed wide distribution ranging from Zagros, Elburz to Khorassan Mountains. 7. A very big problem for the full revision of the genus was the treatment of the short, incomplete, uninformative descriptions and missing of several informative and decisive taxonomic characters in the all prepared descriptions. The author patiently could separate the distinct species and give rise to functional identification keys and distribution pattern for all species distributed in Iran. Morphological characters of the plants in flowering stage are compeletly different from those of fruiting stage. For this reason, the author tried to prepare functional identification keys to the species in both stages. MATERIALS AND METHODS The specimens of different herbaria including TARI, IRAN, TUH, FUMH (abbreviation based on Holmgren and Holmgren, 1996) were examined. Available literature including De Candolle (1802), (Boissier, 1872), Vassilczenko (1984), Vassilczeko (1988), Ranjbar (1999 and 2008), Naqinezhad et al. (2008) were used to study and identify the materials. Used characters There are very few diagnostic characters among distinct species of the genus, so the species with few cryptic taxonomic characters will be separated from each others. In the present investigation, several characters such as: indumentum, stipules, calyx, flower dissection (standard, wing-petals, keel shape and keel mucron) and pod shape were used. Indumentum. All the species are covered with simple hairs. Direction of the hairs are variable, sometimes in some species two indumentum types are present which differs in the size and direction. e. g., in O. azarbaijanica Podlech, O. karjaginii Grossh. petioles and peduncles always are covered with long erect together with short appressed hairs. Sometimes, the calyx and pods are covered with two different hairs in color. There are several species which are covered on the calyx with long straight or speading hairs mixed IRAN. J. BOT. 19 (1), 2013 with short appressed to spreading or curly black hairs. In few cases, the calyx is covered with only long or short white and black hairs. Length of hairs is different from one species to another, so it is a great taxonomic value to separate the closest species. For example, in O. glabra (Lam.) DC. in one plant, there are pods covered with black and white appressed hairs and some pods covered only with black or white hairs. Stipules. Shape, size and adnation of stipules to the petioles are very important to detect the related species. Few species have the stipules which are vaginate and sheathing the stems and at the base shortly adnate to the petioles, such as O. aucheri, O. chrysocarpa. Many species have stipules that highly adnated to the petioles, on the opposite side there are the same features, e. g., in O. hirsutiuscula the stipules minutely adnate to the petiole at the base but in opposite side highly jointed to each other. Based on this character, it is immediately separable from O. glabra. Calyx. The calyx shape in Oxytropis is always campanulate to infundibular with attenuated base or saccate. The ratio of teeth to the tube is very important for separation of the species. Indumentum type icluding size, direction and color are good diagnostic characters. Flower dissection. The size, color and structure of the flowers are very different from one species to another. The standard shape varies among the species, standard shape, length, width and apex are good characters to separate the nearest taxa. e. g., O. karjaginii with dark violet standard is separable from its closest species. O. aucheri has the smaller standard, which is a diagnostic character. There are very few species, which are covered with dispersed hairs on the outside of corolla. Wing-petals in size of limb and claw ratio, apical asymmetric incision give the good idea to segregate the taxa. Length of limb usually is longer than the claw, but rarely is equal. Keel shape in different species and length of its apical mucron, direction of keel mucron play the important role to segregate the species. e. g., in O, savallanica with very short keel and in O. kotschyana with long keel are important characters. Some species with obovate and curved keels are separable from those species with erect keel. Keel mucron is a good charater to separate the closest species. O savallanica, O. iranica, O. hirsutiuscula and O. glabra always bear very short mucron but O. kopetdaghensis, O. kotschyana and O. pilosa always have long straight mucron. In some species, direction of mucron from erect to upward curved or downward status is variable. In few cases, some species show the divided apical mucron which are so hard to recognize. A few species are sparsely pilose on the keel limb, which is very useful to separate the closest species. IRAN. J. BOT. 19 (1), 2013 Maassoumi 4 Pods. There are several form of pod in Oxytropis e. g., ovate-oblong, oblong-elliptic, falcate (luniform), erect, narrowly elliptic and inflated. These features of pod shape with different type of appressed or ascending short and long, black or white hairs help to distinguish the nearest species from each other.Valves texture is very different, e. g., O. persica with thin valve and inflated pods is simply separable from O. savallanica, O. iranica and O. immersa.

Typus: Kermanschah: in angustiis Tengi-Dinawar, Strauss (LE, photo jstore site !). Oxytropis straussii Bornm. was described based on an incomplete specimen. In the description, there is no explanation about the keel structure, because the type material is in fruiting stage and there was no complete flower to describe keel. The author checked both descriptions and type photos (Jstore website 2012) together. All given data on A. ciceropsis was totally matched with those of O. straussii and therefore they are regarded as synonyms. A. podocarpus C. A. Mey. Verz. Pfl. Cauca.: 142(1831). Typus: Talysch, pr.

O. thaumasimorpha was described based on an incomplete material of Sojak collection. In the description, it was mentioned the keel with short mucron. It is necessary to add that in A. podocarpus, the keel apex is nearly rounded not tapering to a short visible mucron. In the same collection, other specimens under number “Sojak 7762” which is not very far from type locality was cited clearly as A. podocarpus (see Fl. Iranica 178: 123 (2010).

O. alavae was described based on very poor material. In the original description there is no information about flower structure such as standard, wing and keel. The author checked both descriptions and all given data together. It is necessary to mention that several specimens were collected from Khalikuh”Ghali Kuh”. On the other hand, A. longirostratus (iso: Recinger 47899 from the same collection) show the wide distribution from Bakhtiari, Esfahan and extended to Luristan which is clearly mentiond in Fl. Iranica (see no.178:43 (2010). A. singarensis Boiss. & Hausskn. in Boiss., Fl. Or. 2: 263 (1872). Typus: Iraq: In monte Ginjar Mesopotamiae, H. CA.

Typus: Afghanistan: In decl. occidentalibus jugi Shibar, 2800 m, Hedge & Wendelbo (W-4233 BG, photo jstore site !). O. wendelboi was described based on the materials from Afghanistan. In the short note in Fl. Iranica (p. 152), it was explained that the Iranian specimen has not flower to describe the keel structure. So, it is a doubtful species for the Iranian flora. But according to the photo in Fl. Iranica, it is mentioned the length of keel mucron is about 2-2.5 mm long, this feature seems that long beak of the mature pods expanded from the keel apex, was given instead of keel mucron. Therefore, distribution pattern of A. singarensis stretch to Afghsnistan, which show a big disjunction with the collected specimens from Iran. A. daenensis Boiss. in sched Imp. Ad Th. Kotsch, Pl.

J. BOT. 19 (1), 2013 Specimens cited for O. kermanica are a mixture of species. Specimens from Qashqai are clearly coinciding with A. daenensis, but specimens cited from Mazandaran and Tehran (central Elburz) are A. aestivorum Podlech, (see Fl Iranica no. 178: 30 (2010), specimen no. Wendelbo 1284 is the holotype of A. aestivorum. This Oxytropis species was basically described on the materials, for which the previous author did not deeply check the precise structure of the keel beak. Surprisingly the distribution pattern of O. kermanica was expanded from Kerman to central Elburz. This is a big misidentification of the herbarium specimens. The specimen Wendelbo 1284 from central Elburz is clearly the type of Astragalus aestivorum Podlech Among the cited specimens the specimen, Behboudi 1082, 1067(IRAN !) is clearly A. daenensis” and the specimen Terme et al. 39831 (IRAN!) is clearly “O. persica”. 2. EXCLUDED SPECIES FOR THE IRANIAN TERRITORY. O. czapan-daghi B. Fedtsch, Fl. URSS. 13:543(1948). Typus: Turcomania: Ad summum m. Czapan-Dagh, Bobrov (LE). Specimen Terme et al. 36737-E, which is mentioned in Fl. Iranica, 157: 134 as O. czapan-daghi is in fact O. binaludensis Vassilcz. 3. DOUBTFUL SPECIES Following species was established based on the young plants in flowering stage, for which not easy to separate it from its related O. chrysocarpa Boiss. O. rudbariensis Vassilcz., Bjill. Nosk. Obsca.Isp. Prir., Otd. Biol. 93 (3) 97-102 (1988). Typus: Guilan: Auf der Felsostellen der Berge bei Rudbar in Cefidrut(rud) elev., Pichler (W). According to the incomplete description, the presence of dark black punctuation on the leaflets is not common in Oxytropis species. This character is a diagnostic character of one species from Astragalus sect. Incani, namely A. demavendicus Boiss. & Buhse (=A. rudbaricus Bunge) from the same area. The type of indumentums and lenght of keel mucron cited in the description need more investigation to understand the taxonomic position of O. rudbarensis. 4. ENUMMERATION OF SPECIES 1.

O. shirkuhi was established based on an incorrect herbarium specimen number “ Foroughi & Assadi 17989” from TARI. It is surprising that according to the field booklet deposited in TARI, the same number “17989” is Gagea stipitata which is mentioned in Fl. Iranica (see Fl. Iranica no. 165: 48 (1990). So probably the type specimen number should be “ 17979 or 17980”. In this case, these later numbers cited as A. abditus Podlech (see Fl. Iranica no. 178: 29 (2010), which was, herein, changed to A. yezdii (Vassilcz.) Podlech & Maassoumi. So it is supposed that the correct number of the type should be “17982” which is confirmed with the field booklet. 8. O. cinerea Vassilcz., Fl.

Species O. hirsutiuscula is widely distributed in Yazd, Shirkuh mts. This species is very variable in terms of shape and size of leaflets, but in all specimens the feature of stipules are similar which are shortly adnate to the petiole at base and in opposite side highly jointed to each other. This important taxonomic character helps to separate also from O. heratensis Bunge from the same area. 13. O. hysophila Bunge ex Boiss., Fl. Or. 2: 501 IRAN. J. BOT. 19 (1), 2013 Fig. 2.
