326 GLEASON: STUDIES ON WEST INDIAN VERNONIEAE 
kept separate since good material for examination was lacking. 
The island of St. Thomas is accordingly added to the known 
distribution of V. albicaulis. It has been collected in St. Thomas 
by others also, and is represented in the herbarium of the Field 
Museum by two sheets, Millspaugh 522 and Eggers 34. 
Vernonia longifolia Pers. To the distribution of this species 
may be added St. Martin, Boldingh 2641, and Montserrat, Shafer 
172, 589, 659, O61. 
Lepidaploa, Scorpioideae reductae 
Vernonia arctata Gleason. The species was originally described 
(Bull. Torrey Club 33: 185. 1906) from New Providence Island, 
of the Bahama group, but is now known to occur also throughout 
Andros Island, Small & Carter 8506, 8613, 8759, 8890, Brace 5170, 
6754, 6926, 7138. Field data show that the flowers vary from 
purplish white to bright rose-purple and that the plant reaches a 
height of 2 meters. 
Vernonia bahamensis Griseb. Reported by Gleason (Bull. 
Torrey Club 33: 187. 1906) from Fortune Island and Inagua, 
it is now represented also by specimens from Crooked Island, 
Brace 4851; Acklin’s Island, Brace 4330; Salt Cay, Millspaugh & 
Millspaugh 9249; Long Cay, Brace 4152, 4020, 4115; Mariguana, 
Wilson 7461; Castle Island, Wilson 7783; Cotton Cay, Mills- 
paugh & Millspaugh 9362; North Caicos, Wilson 7721, Millspaugh 
& Miullspaugh 9175; East Caicos, Millspaugh & Millspaugh 9082; 
and South Caicos, Wilson 7688. The last specimen cited has 
leaves subacuminate or merely acute at the base, 5 cm. long by 2.5 
cm. wide, and in general closely approximates V. albicaulis Pers. 
The Scorpioideae reductae have been considered (Gleason, Revi- 
sion, 165, 166) as related by origin to the species-group Longifoliae, 
to which V. albicaulis belongs, and the theory is strengthened by 
the strong superficial resemblance just mentioned. It is interest- 
ing to note that V. bahamensis occupies the southeastern portion 
of the Bahama archipelago, nearest the area of the Longifoliae, 
and that the particular specimen comes from South Caicos, which 
is almost the extreme southeastern island of the group. 
Vernonia complicata Griseb. In the type collection, Wright 
2790, the leaves are all entire, subrotund, and about 5 mm. aie
