I. acaulis Schott & Kotschy ex Boiss., Fl. Or. 3:195 (1875). Ic: Gard. Chron. Ser. 3, 56:246 (1914). Rhizomatous perennial. Flowering stems usually less than 5 cm, sometimes up to 20 cm, unbranched, often purplish and bearing white, spreading, villous hairs. Basal leaves oblanceolate or spathulate, 3-6 x 0∙6-1∙5 cm, acute at apex, attenuate at base, margin entire, finely glandular on both surfaces, ciliate and with a few hairs on the midrib when young; cauline leaves similar, decreasing in size. Capitula solitary, radiate. Involucre 1∙5-2∙5 cm broad; phyllaries subequal, outer oblong, 6-9 x 1∙5-2 mm, ± foliaceous, glabrous or hirsute at margin; inner lanceolate, acuminate, 1-1∙3 cm, membranous, usually purplish. Ray flowers 20-35, ligules (6-)10-15 x 1-2∙5 mm. Disc flowers 6-8 mm. Achenes adpressed-pubescent, 2-3 mm. Pappus whitish, 6-8 mm, hairs c. 35, scabrous, ± connate at base. Fl. 7-8. On open wet rocks and marshy slopes, 1350-3600 m. 1. Capitulum subsessile on short flowering stems (up to 5 cm); basal rosettes dense: cauline leaves generally absent var. acaulis 1. Capitulum on long flowering stems 6-20 cm; basal rosettes scanty; cauline leaves present var. caulescens var. caulescens Nâb. in Publ. Fac. Sci. Univ. Masaryk Brno 52:6 (1925). Syn: I. hakkiarica Nâb.in Publ. Fac. Sci. Univ. Masaryk 52:5, t. 1 f. 2 (1925)! Type: [Turkey C9 Siirt] Halakur Dag, 2000 m, Nâbelek 3503. E. Anatolia.

B7 Erzincan: Sipikör Da., Sint. 1890:3274! B9 Van: 20 km N.N.W. of Başkale, 2800-2900 m, Watson et al. 3668! C9 Hakkari: Kara Da. above Çölemerik, 2745 m, D. 24320! C10 Hakkari: Mor Da., 2750-3600 m, Watson et al. 3626!Soviet Armenia. Plants of I. acaulis, particularly from S. Anatolia (C4/5), are very small and acaulescent, with involucres about 1∙5 cm broad and glabrous phyllaries. Generally speaking, the plants from further north and east tend to be larger in their stems and involucres. Also, it is noticeable that there is a correlation between ciliate or hirsute phyllaries and taller stems. Certainly, hirsute involucres only occur in the extreme south-east (Hakkari). It was this feature, coupled with the 3-headed stem, that led Nâbelek to describe I. hakkiarica, but I. acaulis var. caulescens may have 2 capitula (see D. 31903) and D. 24320 is as hirsute as Nâbelek's type. |
