Stictophyllum Edgeworth.

Herbs or subshrubs, annual or perennial. Stem erect, branched from base or middle. Lower stem leaves pinnately divided or entire. Capitula homogamous, several, solitary at end of stem and branches. Involucre campanulate to hemispheric. Phyllaries subulate to subulate-lanceolate, very narrow, unappendaged or with an awnlike appendage. Florets bisexual. Corolla purple, pink, yellow, or whitish. Stigmatic branches divergent. Achene with a denticulate rim at apex. Pappus elements in many rows or absent; outer pappus elements shortly plumose, scabrid, or serrulate, distinct or basally connate into a ring; inner pappus elements scarcely longer and basally wider, flattened.

About 17 species: Asia; three species in China.

There is one specimen of Tricholepis roylei J. D. Hooker from "Tibet." However, this is probably erroneous or is from a locality outside of China but referred to as "Tibet" in a historical sense. This species is only known from Himachal Pradesh, India, and it is very unlikely to occur in China.
