206 ENGLISH BOTANY. 
Group C— FOLIOSA. 
Stem leafy, without a basal rosette, corymbosely or paniculato- 
corymbosely branched at the apex. Lower stem-leaves narrowed 
at the base ; middle ones sessile or semi-amplexicaul ; uppermost 
ones amplexicaul or semi-amplexicaul or sessile; all paler and 
frequently slightly glaucous beneath, with the network formed by 
the ultimate veins more or less conspicuous. Phyllaries numerous, 
imbricated in several rows, dark, with pale margins, sparingly hairy, 
sometimes with a few gland-tipped hairs, none of them squarrose 
at the points. Achenes chestnut when ripe.

Stem very leafy, corymbosely or paniculato - corymbosely 
branched at the apex, sub-glabrous, or sparingly clothed with 
woolly hairs below and a little stellate down above ; peduncles 
rather densely clothed with stellate down, but with few or no 
gland-tipped hairs. Leaves dispersed over the whole stem ; the 
lowest ones oblanceolate, narrowed towards the base, sub-petiolate, 
with very short broadly-winged petioles ; intermediate ones rhom- 
boidal - elliptical or -oval-elliptical, attenuated towards the base, 
semi-amplexicaul or sessile, acuminate ; uppermost ones lanceolate 
or ovate-lanceolate, rounded and semi-amplexicaul at the base, acu- 
minate or attenuated towards the apex ; all more or less strongly 
serrate-dentate in the middle with the teeth rather remote and 
very acute, glabrous above, pale and slightly glaucous beneath, with 
the network formed by the ultimate veins rather conspicuous, sub- 
glabrous, frequently with distant short hairs on the veins and 
margins. Anthodes moderately large, numerous, in a compound 
corymb or short panicle terminated by a corymb, with rather 
slender spreading-ascending peduncles generally furnished with a 
lew minute bracts which usually do not pass gradually into the 
outer phyllaries. Pericline hemispherical at the base; phyllaries 
rather numerous, obtuse, the inner ones much broader than the 
others, dark-olive with paler margins; all sparingly sprinkled along 
the middle line with short whitish hairs and a few gland-tipped
