C h e i l a n t h e s l a n u g in o s a : — Stalks densely tufted, slender,
brownish-black, at first clothed with spreading woolly hairs, at
length nearly smooth; fronds two to four inches long, one to one
and a half broad, ovate-lanceolate, tripinnate, or bipinnate with
crenately pinnatifid pinnules; pinnæ varying from deltoid to
oblong-ovate, the lowest ones distant, the upper ones gradually
closer; the ultimate pinnules minute, not more than half a line
long and broad, or the terminal one more obovate and a little
longer, — all very much crowded; upper surface scantily tomentose,
the lower densely matted with soft whitish-brown distinctly
articulated flattened woolly hairs; involucres very narrow,
formed of the unchanged herbaceous margin of the segments.
