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, Mills pan gh 522 and Eggers 34. 



Vernonia longifolia Pers. To the distribution of this species 

 may be added St. Martin, Boldingh 2641, and Montserrat, Shofer 

 172, 589, 659, 661. 



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 5176, 

 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, Millspaugli & 

 Mills pan gh 9249; Long Cay, Brace 4152, 4020, 4115; Mariguana, 

 Wilson 7461; Castle Island, Wilson 7783; Cotton Cay, Mills- 

 pangh & Millspaugli 9362; North Caicos, Wilson 7721, Millspaugli 

 & Millspaugli 9175; East Caicos, Mills pan gh & Millspaugli 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 complicate Griseb. In the type collection, Wright 

 2790, the leaves are all entire, subrotund, and about 5 mm. long.
