v Chrysopsis caudata sp. nov. 
Perennial, with a thick tap-root and a very short, erect and 
much-branched caudex ; stems many, erect, purplish, hirsute with 
long white hairs; lower leaves oblanceolate, tapering into a short 
petiole, silky-strigose on both sides, 3-5 cm. long ; middle leaves 
similar but sessile, uppermost elliptic or oblong ; heads congested 
in small clusters at the end of the branches and subtended by the 
uppermost leaves ; bracts linear-lanceolate, hirsute, the innermost 
with a subulate usually brownish and spreading tip ; disk about 15 
mm. wide ; rays bright yellow, about 12 mm. long and 3 mm. wide. 
This species is closely related to C. vil/osa, but differs in the 
sessile heads subtended by oblong leaves and in the subulate tips 
of the involucral bracts. It grows on hills at an altitude of 1500- 
2950 m.,

nial, with a tap-root, rather simple ; stem 3-5 dm. high, 
ties Fes pubescent and sparingly hirsute ; ee leaves 
spatulate, strigose, obtuse or slightly mucronate, middle and upper
