294 Plant. nov. in Florida subtropica indigenae a John K. Small descriptae. 
Florida: The type-specimens were collected in the pinelands between 
Cutler and Camp Longview in XI, 1903 (Small & Carter, no. 870). 
Specimens similar to the originals were found in the homestead region 
by Dr. Britton in III, 1904 (no. 191). 
30. Melanthera ligulata Small, |. c., p. 439. 
Perennial, often luxuriant: stem commonly branched at the base and 
above, the branches spreading or ascending, 4— dm long, finely pubes- 
cent: leaves conspicuously elongated; blades linear or nearly so, mainly 
8—17 cm long, irregularly toothed and sometimes salient at the base, 
attenuate into long petioles: heads long-peduncled: involucres partly 
foliaceous, the outer bracts surpassing the disk, linear-lanceolate, 11— 13 mm 
long, finely pubescent; the inner bracts lanceolate, 8—10 mm long, acu- 
minate: bractlets linear-lanceolate. 5,5— 6,5 mm long, pubescent at the 
tip: corollas 5—6 mm long; lobes ovate: achenes not seen. 
A species related to Melanthera lanceolata Benth., but readily separated 
by the peculiarly elongated leaves and the foliaceous involucre with its 
long and acuminate bracts. 
Florida: The type-specimens were collected in the pinelands below 
Ft, Lauderdale, by Mr. P. Wilson and the writer, in V, 1904 (no. 1775). 
31. Carduus vittatus Small, |. c., p. 439. 
Perennial, the rootstock often branched: stem 4—7 dm tall, simple, 
ridged in age: leaves mainly basal; blades elongated-linear, mostly 1—3 dm 
long, acute, spinescent-ciliate on the margins, thinly floccose on each sur- 
face; stem-leaves few, remote, erect or ascending; blades shorter than 
those of the basal leaves, more coarsely spinescent-ciliate, clasping at 
the base: involucre subtended by a series of spine-armed bracts, hemi- 
spheric-campanulate, nearly 3 cm high; bracts acuminate, ciliate, the 
outer lanceolate, the inner ones linear-lanceolate or nearly linear, sur- 
passing the spine-armed outer bracts: anthers twice as long as the free 
portion of the filaments: achenes 3— 3,5 mm long, glabrous, angled: 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. 
Florida: The type-specimens were collected in the everglades west 
of Camp Jackson in V, 1904 (Small & Wilson, no. 1874). Other spe- 
cimens belonging here are: Between Cutler end Camp Longview (Small 
& Carter, no. 1087). Near Camp Congview (Small & Wilson, no. 1794).
