tacle with numerous” long, linear, chaffy scales. Florets of 
the ray five to six, large, white. Corolla broadly-obovate, 
marked with lines, three-toothed.. Corollas of the disk 
numerous, yellow, tubular, five-toothed. Anthers black- 
purple. Stigma bifid, the segments linear, spreading, hairy. 
Achenium linear-oblong, compressed, margined, the edges 
scabrous, the short bristles pointing upwards. The Pappus 
consists of two erect, rigid bristles, retrorsely scabrous. 
This is one of the many interesting plants introduced to 
our gardens by the late Mr. Barctay from Mexico. Itis 
the more desirable from being quite hardy, if treated as an 
annual, although the root is, probably, perennial, and from 
blossoming late in the autumn. The flowers are abundant, 
and conspicuous from their large white rays.
