Project Data     (Last Modified On 6/3/2011)
General/Distribution: A medium sized genus with c. 30 species distributed in Europe, Asia and N America. Represented in Pakistan by 8 species. Leontopodium is an intricate genus, probably most of the species are apomictic. Little work has been done on our Himalayan plants. It is difficult to construct a satisfactory key as most of the specis are highly variable. Experimental and field studies are needed to resolve the problem.

Perennial, tufted or stonoliferous, usually densely white tomentose, herbs. Leaves alternate, simple, entire, cauline ones few to many, basal leaves usually in rosettes. Capitula terminal, solitary or in clusters of 3-12 (-20), usually surrounded by conspicuous spreading bracts, different in colour, texture of the indumentum and size from cauline leaves, forming a star-like structure, rarely neither a star like structure formed nor the bracts different from the cauline leaves (L. nanum). Florets unisexual, capitula usually either discoid and dioecious or disciform. Involucre campanulate; phyllaries dark brownish, pluriseriate. Receptacle flat or convex, epalaceous. Marginal florets female outnumbering the central florets, filiform, corolla yellow, 3-4 toothed, disc florets functionally male, tubular-campanulate, corolla yellow 5-toothed. Anthers linear, caudate. Cypselas oblong-ellipsoid, sparsely hairy to glabrous with short clavate or myxogenic twin hairs; pappus setae barbellate, basally connate, deciduous.

1 Inflorescence bracts spreading forming a star-like structure, distinctly differing in colour, texture of indumentum or at least in size from the cauline leaves. (2)
+ Inflorescence bracts neither forming a star-like structure nor differing from the other cauline leaves. Leontopodium nanum
2 (1) Plants not as above. Floriferous stalk thick. Leaves covered by ash white tomentum. (3)
+ Mat forming herbs with very slender, floriferous stalks. Leaves densely covered with long yellowish, grey tomentum. Leontopodium monocephalum
