DESCRIPTION:--A somewhat woody undershrub about 30 cm. high with deep
underground roots. _Stems_ striate, cobwebby. _Leaves_ 5·5-7 cm. long,
1-1·7 cm. broad, lanceolate, acute, or obtuse, sometimes subacuminate,
slightly broadened and half-clasping at the base, usually entire, more
rarely minutely and remotely toothed, glabrous above, cobwebby beneath.
_Capitulum_ shortly peduncled, about 5 cm. in diameter when expanded.
_Involucral-bracts_ in about 8 rows, the outermost strongly reflexed,
the rest erect spreading, 1·5-2·5 cm. long, 4-9 mm. broad, ovate,
acuminate, pungent, with membranous margins (except the outermost); the
innermost bracts erect, closely enveloping the flowers, almost wholly
membranous. _Involucre_ 1·5 cm. in diameter, slightly convex, deeply
honeycombed. _Flowers_ all hermaphrodite. _Corolla-tube_ 6 mm. long,
cylindric for 5 mm. then suddenly campanulate, glabrous; lobes 4·5 mm.
long, linear, gradually tapering upwards, obtuse, recurved in open
flowers. _Stamens_ inserted at the widened portion of the corolla-tube;
filaments 1·5 mm. long, linear; anthers 7·5 mm. long, linear,
lanceolate, acute at the apex, long-tailed at the base; tails hairy with
ascending hairs. _Ovary_ densely villous; style 1·5 cm. long, cylindric,
glabrous; lobes 0·5 mm. long, ovate, obtuse, convex and hairy on outer
side. _Pappus_ 9 mm. long, dense and completely hiding the corolla-tube;
setae long, plumose.
