British Museum, Houstoun’s ‘‘ Chrysanthemum americanum fru- 
tescens; Balsamino luteo foliis, nigris maculis punctatis. Pluk. G. 
161. f. 1.,’ quoted as ‘‘ Eupatorium americanum &c.” by Miller, 
is the same as Porophyllum nummularium DC., and his name must 
replace it as being much the oldest name for the species. The 
type, a tracing of which is now in the Gray Herbarium, is erect, 
herbaceous, sparsely branched; the involucre in bud 10-12 mm., 
in fruit 12-13 mm. high; achenes brownish-black, puberulous 
with ascending hairs, 6.3 mm. long; pappus 8.5 mm. long; corollas 
in fruit 9-10 mm. long; leaves with glands on surface as well as 
on the margin; and peduncles not at all clavate upwardly.

(TYPES in Gray Herb. and U.S. Nat. Herb.). — Distributed as 
C. amplifolia DC., from which it differs in being glabrous, in its
