fibres, apparently perennial; stem costate-sulcate, glabrate, 
branched above at the inflorescence; branches angular, leafy, 
more or less clothed (as are also some of the leaves and in- 
florescence) with white papery-floccose deciduous or obsolete 
patches ; radical or lower leaves narrowly elliptic-oblong, narrowed 
at both ends especially towards the petiolate base, glabrescent, 
herbaceous, ranging up to more than 2 ft. long (inclusive of the 
petiole) by 2 in. broad, crenulate-denticulate on the subcarti- 
Jaginous margin uninerved; the petiole clasping; stem-leaves 
similar but smaller and the upper ones sessile, alternate ; capitula 
heterogamous, radiate, calyculate, campanulate, numerous, about 
50-flowered, 2 to $ in. long, on bracteate pedicels ranging up to 
1} in. long, arranged in rather dense corymbose terminal cymes 
of about 6 in. in diameter; bracts narrow; calyculus consisting 
of several smaller bracts similar to those of the inflorescence ; 
flowers golden-yellow ; involucral scales about 17, subglabrescent, 
linear-oblong, about + to + in. long, lance-shaped towards the 
ciliolate apex, scarious on the imbricate margins ; female florets 
about 8, ligulate, marginal, uniseriate, fertile, about 4 in. long, 
with a short bifid style, a glabrous ribbed and subecompressed ovary, 
and setose whitish barbellate rather copious subuniseriate pappus ; 
the ligule oval, very shortly 3-lobulate at the apex ; hermaphrodite 
florets discoid, pluriseriate, about 42, tubular, + in. long ; the corolla 
shortly 5-lobed, glabrous; anthers about equalling the corolla, at 
length shortly exserted, obtusely appendaged at the apex, obtuse 
and not appendaged at the base ; style-branches short, somewhat 
flattened, very obtuse and stigmatose at the apex, equalling the 
anthers; ovary glabrous, subcompressed, ribbed; setz of the 
pappus pauciseriate, whitish, minutely setulose, rather copious,
