绒毛粉背蕨(原变种) rong mao fen bei jue (yuan bian zhong)

Cheilanthes subvillosa Hooker, Sp. Fil. 2: 87. 1852; Aleuritopteris subvillosa var. dilatata (Brause) H. S. Kung; C. yunnanensis Brause; C. yunnanensis var. dilatata Brause; Leptolepidium subvillosum (Hooker) K. H. Shing & S. K. Wu; L. subvillosum var. dilatatum (Brause) K. H. Shing & S. K. Wu.

Lamina hairy but lacking farina abaxially at maturity, sometimes somewhat white farinose when young.

Under shrubs and in rock crevices; 2000-3900 m. Guizhou, Sichuan, Xizang, Yunnan [Bhutan, India, Myanmar, Nepal].

Although plants of Aleuritopteris subvillosa var. subvillosa are easily distinguished from the relatively densely farinose var. tibetica, there is a lot of variation among populations. In most cases, plants with non-farinose mature fronds produce at least some farina on fiddleheads. Additionally, some plants have sparse abaxial farina persistent on mature fronds.
