Ae. grandiflorum Boiss. & Hohen. in Boiss., Diagn. ser. 1(8): 42 (1849). Syn: Ae. pulchellum Boiss. & Huet in Boiss., Diagn. ser. 2(5): 43 (1856). Many-stemmed perennial herb with simple or branched flowering stems, 15-30 cm. Leaves narrow, linear-oblong, sessile, evenly covering the stem. Petals pink 5-11 x 3.5 mm, blade and claw distinct or not, blade 3-nerved. Filaments not or scarcely connate, slightly dilated, not dentate. Inflorescence loosely racemose, elongating in fruit. Ovary bilocular, loculi 1-ovulate. Fruiting pedicels suberect, 3-4 mm. Siliculae ovate or orbicular, flat or slightly cymbiform, 8-10 x 10-12 mm; wings 2-3 mm entire or slightly erose-dentate; sinus 3-4 mm; style subsessile; septum 3.5-5 x 2.5 mm. Seeds 1-2. Fl. 5-6. Dry rocky slopes, c. 1000-3000 m. Type: Iran, in fauce Schirdere montis Elburs, Kotschy 181 (E!). E. Anatolia. A8 Erzurum: Horasan to Karaurgan, 2000 m, D. 29495! A9 Erzurum: Pasinler to Horasan, 1650 m, D. 29411! B7 Tunceli: above Pülümür, 1850 m, D. 29291! Malatya: Malatya to Pütürge, 1730 m, Hub.-Mor. 9248! Erzincan: Egin (Kemaliye), Sint. 1890: 2377! B9 Bitlis: Pelli Da., 3050 m, D. 22474! Bitlis/Van: mountain 10 km SE of Pelli, 2440 m, D. 22594! C6 Gaziantep: Dülük Baba, 1100 m, D. 28043! Malatya: Erhenek, 1400 m, Balls 2311! Transcaucasia, Iraq & Iran. Ir.-Tur. element. Widespread and very common in eastern Turkey. Very variable in all its characters and apparently consisting of innumerable interconnected local forms. Although the two species Ae. grandiflorum and Ae. pulchellum have usually been kept as separate species, many authors (e.g. Bornmüller, Blakelock) have remarked that there are transitions between them. On the basis of the abundant Turkish material, there is no justi fıcation in maintaining two separate taxa. Both petal size and shape are most variable and the larger-flowered taxon which is more common in Iran can apparently only be recognised in flower. |
