E. L. EKMAN, WEST INDIAN VERNONI^. 85 



t'ourKl these differences striking enough to warrant its assign- 

 ment as a subspecies of V. sericea: 



subsp. racemosa (Delponte) Ekman n. subsp. 



Tabula nostra V, fig. 4 (habitus). 



Folia quam in specie tenuius pubescentia, subtus sordide 

 grisea, raro subglabra; inflorescentia magis contracta, cymis 

 brevioribus; squamae involucri brevius acuminatae, subvio- 

 laceo-brunnese. Pappi setae interiores 35 — 45 exterioribus 

 8-plo longiores. Antherae 1,2 mm longse. 



Vernonia racemosa Delponte, 1854, p. 396.

 Ehrenberg n. 9 (B, p. p.), n. 150 (B); Picarda n. 145 (KU);

Though in its typical forms well distinguished from 

 V . sericea, the subspecies cannot always be recognized on 

 habitual characters only. Especially the specimens collected 

 by SwARTZ, which Wikström took to be V. divaricata Sw., 

 strongly resemble V. sericea. Yet I think the larger anthers 

 will prove to be a good analytical character of the subspecies. 

 Its particular distribution may prevent confusion with F. 

 sericea. 



The material at hand is extraordinarily heterogeneous. An 

 exclusive type is Türckheim n. 2905 with narrowed, revolute 

 leaves (dim. 4 X 0,3 — 0,5 cm) and very dense inflorescence. 

 The plant collected by Buch has leaves resembling those of 

 V. albicaulis Pers. or V . membranacea Griseb., and unusually 

 evoluted floral branches. 



All specimens seen from Hispaniola have been found 

 to belong to the subspecies except Mayerhoff in 1852 (B). 

 However, this plant may have been collected in another island,
