290 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
А stout herb, glabrous throughout or slightly white-tomen- 
tulose on the under leaf-surface; stem erect, 1 to 1.5 m. high, 
branched, striate; leaves 3 to 10 сш. long, mostly deeply 
bi-tri-pinnatifid with few linear to linear-lanceolate divergent 
sharply dentate lateral divisions; inflorescence a terminal 
compound corymbose many-headed eyme; heads about 1 em. 
high, radiate; involuere eampanulate, calyculate; bracts of 
the involuere linear-attenuate, 5 to 6 mm. long; ray-flowers 
9 to 13, rays yellow ; disk-flowers numerous, about 50; achenes 
hispidulous.—Florida: on ballast ground, Hunter's Wharf, 
Pensacola, 15 May and June, 1893-1894 (U. S. Nat. Herb. 
Nos. 720457, 782498). 
This species is allied to S. brasiliensis Less. and in the 
‘Index Kewensis’ is said to be synonymous with it. In the 
Herbarium of the Missouri Botanieal Garden there is for- 
tunately an authentie specimen of S. brasiliensis, namely Mar- 
tius 770. Lessing's species is also well represented by speci- 
mens collected by Dr. J. N. Rose on an expedition to South 
Ameriea under the auspices of the Carnegie Institution of 
Washington and the New York Botanical Garden, namely 
Rose & Russell 20604 from the vicinity of Itatiaia, Brazil, and 
Hose & Russell 20760 from the Organ Mountains, Rio de 
Janeiro, both of which are in the U. S. National Herbarium. 
The general aspect of the two species is very similar, but 
S. brasiliensis has entire leaf-segments, a narrowly campanu- 
late involucre, longer and fewer involucral bracts, and fewer 
flowers in the head. From the several specimens at hand the 
two species seem to be amply distinet. Whether S. canabinae- 
folius Hook. & Arn. has persisted at Hunter's Wharf is not 
known to the writer.

The common ‘‘fireweed,’’ Erechtites hieracifolia (L.) Raf., 
which is one of the first plants to appear on a freshly burned 
area, has become wide-spread throughout North America; it 
is well known and is copiously represented in every large 
herbarium. In our general and local floras it is the only
