B. L. EKMAN, WEST INDIAN VERNONIiE. 95 



Subsect. Noveboracenses. 



Suffrutices elati. Folia membranacea. scepe angnsta, in- 

 tegerrima vel margine scepe serrulata. Inflorescentia cymoso- 

 -paniculata, plana vel concavo-depressa, ambitu obpyramidata, 

 cymis satis brevibus, exterioribus inferioribus longioribus, scepe 

 sursum arcuatis; bracteis nullis. Calathidia scepe majuscula. 

 Involucrum late campanulatum. Receptaculum planum, nudum. 

 Pappi setce interior es persistentes, numero 40 70, tenues, fili- 

 formes, scepe purpurascentes, exterioribus subindistinctis, ince- 

 quilongis, anguste linearibus vulgo 8-plo longiores. Corollce satis 

 longce, 8 10 mm in speciebus examinatis, glabrce, tubo 2 / 3 long, 

 corollce. Antherce ultra 3 mm longce, ligula 1 /. 1 / 6 long, antherce, 

 auriculis obtusis. Achcenia subglabra. 



This subsection includes several Mexican species, and all 

 North American ones. It matches Gleason's Paniculatce verce, 

 except his Alamaniance. It differs from the Polyanthes chiefty 

 in its flat or depressed inflorescence, larger corollas and anthers, 

 and nearly glabrous achenes. 



Only one West Indian species belongs here, viz. V. insu- 

 laris Gleason, described as from the Bahama Islands. Evi- 

 dently the origin of this species can be traced back to Florida, 

 where related species are common. 



Vernonia insularis Gleason.
