| H. crenatifolium Boiss., Fl. Or. 2:1045 (1872). Syn: H. davisii Manden. in Notes R.B.G. Edinb. 24: 178, f. 1 (1962)! Map 72, p. 497. Biennial(?), 0•7-1•5 m, not aromatic(?). Stem solitary, more than 1•5 cm diam. below, finely striate-sulcate, glabrous. Basal leaves 1-2-pinnate, lamina triangular-oblong, at least 40 cm long, subglabrous to sparsely pubescent above, more densely pubescent below; primary pinnae 2-4-paired, 1-pinnate to pinnatifid, the terminal one 3-lobed to 3-sect; ultimate lobes oblong-lanceolate, crenate-dentate to dentate. Upper cauline leaves with an oblong-lanceolate sheath. Rays 35-50, ± unequal, 2-12 cm, glabrous. Bracteoles lanceolate to filiform. Flowers unknown. Fruits elliptic-obovate to suborbicular, 7-15x6-11 mm, emarginate, sparsely adpressed-setulose; dorsal vittae broadly linear-clavate (up to 1 mm broad), c. ½ as long as mericarp; commissural vittae 2, ¼-? as long as mericarp. Fl. 5-6. Edge of montane forest, meadows, by streams, ascending to 2400 m. Type: [Turkey A7 Trabzon] in Ponto ad margines sylvae supra Trapezuntem (Trabzon), Bourgeau, sub H. persico (K! G. photo!) N.E. and E. Anatolia. A8 Gümüşane: Aşkale to Bayburt, Kop Da. pass, 2400 m, Lamond 2599! B9 Ağri: 15 km from Eleşkirt to Horasan, E. of Tahir pass, 2200 m, D. 47127! Bitlis: Reşadiye to Pelli, 2000 m, D. 22382 (type of H. davisii)! Endemic. Very variable in fruit size, the type of H. crenatifolium and H. davisii representing the large and small extremes respectively. (Aucher 3600 from 'Lazis-tan' may belong here, though the vittae are longer than usual.) H. amanum Boiss. & Kotschy (Fl. Or. 2:1045,1872) is known to me only from the type (Akmadagh (Amano), Kotschy 46!). This gathering differs from H. crenatifolium in its less deeply divided leaves (having somewhat broader lobes), pubescent rays, and broadly orbicular fruits with broader dorsal vittae up to 1•5(-2) mm broad. The Amanus population may turn out to be no more than a peripheral variant of H. crenatifolium. Greater variation occurs within other species that have been better collected (e.g. H. platytaenium). |
