Melanthera ligulata sp. nov. 
Perennial, often luxuriant: stem commonly branched at the base 
peduncled: involucres partly foliaceous, the outer bracts surpassing 
the disk, linear-lanceolate, a mm. long, finely pubescent; the 
inner bracts lanceolate, 8-1o mm. long, acuminate: bractlets linear- 
nen 5-5-6.5 mm. long, pubescent at the tip: corollas 5-6 
ong; lobes ovate: achenes not see 
ns species related to felanthera te Benth., but readily 
separated by the peculiarly elongated leaves and the foliaceous 
involucre with its long and acuminate bracts. The type-specimens 
were collected in the pinelands below Ft. Lauderdale, by Mr. P. 
Wilson and the writer, in May, 1904 (no. 1775). 
Carduus vittatus sp. nov. 
Perennial, the pea often branched: stem 4-7 dm. tall, 
simple, ridged in age: leaves mainly basal; blades elongated: 
linear, mostly 1-3 dm. ne acute, spinescent-ciliate 
margins, thinly floccose on each surface; stem-leaves few, re ee 
ect or ascending ; blades shorter than those of the basal leaves, 
more coarsely spinescent-ciliate, clasping at the base: involucre sub- 
nearly 3c igh; bracts acuminate, ciliate, the outer lanceolate, 
the inner ones linear-lanceolate or nearly linear, rue est the 
spine-armed outer bracts: anthers twice as long as the free portion 
of the filaments: achenes 3-3.5 mm. long, glabrous, eee pappus 
white, the bristles plumose. 
A small species related to Carduus pinetorum Small; differing 
in the narrow elongated blades of the basal leaves which are not 
pinnatifid, the campanulate involucres and the throat of the corolla 
which is scarcely half as long as the lobes. The type-specimens 
were collected in the everglades west of Camp Jackson in May, 
1904 (Small & Wilson, no. 1874). Other specimens belonging 
here are: 
Between Cutler and Camp Longview, Small & Carter, no. 1087. 
Near Camp Longview, Small & Wilson, no. 1794. 
CHAPTALIA LEIOCARPA (Griseb.) Britton 
This, the second species of Chaptalza for the North American 
flora, was discovered in the everglades near the homestead trail
