ALTERNANTHERA PUNGENS HBK. Nov. Gen. et Sp. 2: 206. 
This South American and Mexican species, which has formerly been 
reported from Mobile,‘ has recently been found by Mr. Curtiss introduced 
about the streets of Pensacola (no. 5921). 
JUSSIZA SUFFRUTICOSA L. Sp. Pl. 388. 
The first record of this plant in the United States was Dr. Small’s recent 
note of Dr. Mohr’s station at Mobile, Ala.2_ Mr. Curtiss found the plant in 
low ground at Pensacola, July 2, 1897 (no. 5918). 
HyDROCOTYLE BONARIENSIS Lam. Encyc. 3: 153. 
This interesting tropical species, which has recently been reported by Mr. 
Pollard from Mississippi,? was collected by Mr. Curtiss in low grassy ground 
at Pensacola, July 3, 1897 (no. 5922), thus making known a second station 
for the plant in the United States. 
SOLANUM ELAZAGNIFOLIUM Cav. Ic. 3: 22. pl. 243. 
This species, common in the southwestern states, has been found by Mr. 
Curtiss in ballast and along streets at Pensacola (no. 5913). 
Vv CHRYSOPSIS GRAMINIFOLIA Ell. var. latifolia, n. var.—Stouter than 
the type; the stems densely leafy: the silvery leaves broadly oblance- 
olate or oblong-lanceolate, strongly 5 to 7-nerved ; the lower cauline 
ro to 15™ long, 2 to 3™ wide, blunt or rounded at the tips; the upper 
shorter, with less rounded or acute tips: inflorescence less diffuse and of 
fewer heads than in the type; the bracteiform leaves linear-lanceolate, 
2 to 3™ long: heads as in the type, but the fusiform akenes longer, 
4°" long, and the pappus shorter, 6™" long. 
Collected in “spruce pine” land, Jensen, March 25, 1897, by A. H. Cur- 
tiss (no. 5819); and in 1874 in east Florida (no station given) by Dr. Edward 
Palmer (no. 259). A plant habitally well distinguished from C. graminifolia, 
but passing by various gradations to it. The akene and pappus characters, 
which on the whole are good, are not strictly to be relied upon. In typical 
C. graminifolia the akenes average 2.5 to 3™ in length, but in large speci- 
mens they are fully 4™™ long, thus equaling those of var. /atifolia. The p@P- 
pus, too, of C. gvaminifolia is inconstant in its length. In most specimens * 
is 8 or 9™™ long, but specimens of good C. graminifolia are found with the 
pappus only 6™" long. The var. /atifolda is well distinguished habitally from 
the species by its approximate broad and obtuse leaves, which in the inflor- 
escence become merely linear-lanceolate, not linear-subulate, as in ¢
