Like 4 but stem more or less glabrous; leaflobes up to 2 mm wide, linear-lanceolate; bracts present, sometimes divided and leaf-like; bracteoles sometimes divided at apex; fruit 17-25 mm. • Kriti (Levka Ori, near Omalos). Cr.

6. C. azoricum Trelease View in CoL , Ann. Rep. Missouri Bot. Gard. 8: 116 (1897).

Robust herb c. 60 cm; stem somewhat purplish. Leaves (l-)2-pinnate; lobes irregularly and jaggedly serrate; petiole, rhachis and lamina with an often dense covering of patent hairs. Bracts 0-3, probably deciduous; bracteoles large and conspicuous. Petals white. Ripe fruit unknown, but probably 15 mm; stylopodium nearly 1 mm, conical; styles patent. • Açores. Az. (7-9). C. hirsutum group. Robust perennials with stems up to 120 cm. Leaves 2- to 3-pinnate. Stems and leaves densely hairy to subglabrous. Bracteoles often unequal. Petals white or sometimes pinkish. Fruit 4-20 mm, narrowly ovoid-oblong, tapering gradually upwards. Styles nearly erect.

A difficult group which requires further investigation. The species here recognized are sometimes treated as subspecies, but as 7 and 9, at least, occur sympatrically in the Alps without intermediates, specific status seems more appropriate.
