Stem erect or T devconad vposailge Heads from 2 to 3 lines 
long. Corolla slender, the ampliate summit minutely 4-toothed 
in the perfect, and 3-toothed in the female flowers ; in the latter 
more slender, but otherwise similar, and destitute of stamens. 
Achenia somewhat narrowed at the apex, apahige: the slender 
nerves ‘minutely serrulate, scabrous under a lens, otherwise gla- 
brous, or nearly so. Drummond’s specimen is much condensed, 
the stems barely an inch high. That from Captain M‘Arthur is 
erect, proliferously branched, and about three inches high, with a 
foliose-bracteate head sessile in each fork of the stem. ‘The genus 
is evidently allied to Panetia, Cass., and Chrysodiscus, Breet, but 
different from both in the two kinds of involucre an pappus: the 
latter in the hermaphrodite flowers consists of narrow palez raise
