terminated by small yellow heads. Leaves few, radical soon disappearing. Heads 
terminal and sublateral, few fld.; pedurcles naked, slender. Achenes } in. long, very 
slender, pale, obscurely scabrid, hardly beaked ; pappus white.—Bentham suggests 
that this and Youngia flexuosa of the Altai are varieties ; Clarke also points out they 
are altogether similar, except in that the Altai plant has a distinct beak to the 
nchenes. 
5. C. tenuifolia, Willd. Sp. Pl. ii. 1605; perennial, quite glabrous, 
stems very many from the root-stock stout much branched stiff, radieal leaves 
long-petioled pinnatifid, lobes distant spreading very unequal slender acuminate 
sparingly toothed or entire, rachis winged, heads corymbose j in. long, invol. 
bracts hoary outer very small inner linear subacute, tips often clawed, achenes 
narrowly fusiform shortly beaked compressed ribbed minutely scabrid about 
equalling the soft silvery pappus. Clarke Comp. Ind. 254. Barkhausia tenui-

Root woody. Stem often branching from the base, 6-18 in. high, stiff. Leaves 
4-8 in., narrow, radical rarely linear and entire, cauline usually so. Heads numerous; 
peduncles bracteate, sometimes sparsely pubescent. Achenes } in., red-brown, slightly 
compressed ; pappus-hairs rather deciduous. 
6. C. japonica, Benth. Fl. Hongk. 194; annual, glabrous or puberulous, 
radical leaves obovate sinuate-toothed or runcinate-pinnatifid, flowering-stems 
slender erect nearly naked, heads 4—4 in. on slender bracteolate peduncles, invol. 
bracts 6-8 narrowly oblong glabrous fruiting with a strong basal midrib, 
achenes narrowly fusiform hardly beaked compressed ribbed equalling or shorter 
than the white soft pappus. ©. lyrata, Clarke Comp. Ind. 253. Youngia

Leaves rosulate, 2-6 in., membranous. Flowering stems 1 or many from the root, 
6-18 in., soft, strict, corymbosely branched at the top; branches slender, spreading. 
Invol. bracts with hyaline margins, erect green. Achenes 45 in., distinctly contracted 
but not beaked at the top, many-ribbed, ribs smooth, red-brown.—Wight suggests 
that this should be placed in the Brachyramphus section of Lactuca, and Clarke says 
that the subgenus Youngia would be better placed under Lactuca. The fact is that it 
will go with either Crepis or Lactuca, but has rather the habit of the former according 
to Bentham’s and my view of the limitation of these very artificial genera. 
7. ©. fuscipappa, Benth. in Gen. PL ii. 574; annual, glabrous or nearly 
so, stem erect slender simple or sparingly forked, radical leaves petioled elongate 
obovate or oblanceolate obtuse acute or acuminate sinuate-lobed or pinnatifid, 
cauline linear or lanceolate base narrow, heads few corymbose j$ in. long, 
peduncles slender naked, outer invol. bracts very small, inner linear subacute 
glabrous fruiting not ribbed at the base, achenes narrowly fusiform hardly 
beaked compressed ribbed minutely scabrid about equalling the soft grey pappus.
