5. The allies of V. membranacea Griseb. 

 Yernonia membranacea Griseb. 



Tabula nostra IV, fig. 3, (inflorescentia). 

 Vernonia membranacea Grisebach, 1SG6, p. 144; Gleason, 1906 b, p. 



180. 



Pappi setae interiores persistentes, numero 40, tenues, 

 filiformes, pallide brunneae, quam exteriores minutissimae 

 circ. 14-plo longiores. Corolla 5,8 mm longa, tubo long. x 2 

 corollae, sensim dilatato, glanclulis nonnullis instructo, limbi 

 laciniis apice subtus papillosis. Antherae 1,6 mm, longse, ligula \ G 

 long, antherae, nervo medio conspicuo, auriculis acutis. 



Hab. in Cuba: Wright n. 490 (G, orig. spec., KU, sine 

 num.); prope Bahia Honda, prov. Pinar del Rio, 18 19. 12. 10, 

 Wilson n. 9426 (KU). 



A well-marked species, which seems to be very rare. As 

 Gleason remarks, its leaves greatly resemble those of V. 

 albicaulis Pers. But the scales of the involucres are very differ- 

 ent, broad, greenish-brown with stramineous margin and nearly 

 glabrous. Structurally, it comes very near to V. gnaphali folia 

 A. Rich., and is, in fact, closely related to that species, but 

 only slightly so to V. albicaulis. 



Yernonia desiliens Gleason. 



Vernonia desiliens Gleason, 1913, p. 316. 



Hab. in Cuba: Oriente, Arroyo del Medio, ad rupes prope 

 ripam rivuli, alt. 450550 m, 20. 1. 10, Shafer n. 3232. 



I have seen no specimens of this species. From the de- 

 scription it seems to be a good one, coming near to V. membra- 

 nacea, from which it differs in having the leaves closely gray- 

 tomentose beneath. As to the characters of the pappus it 

 agrees very well with V. membranacea: pappus light brown, 

 the inner series 6 mm long, minutely barbellate, the outer series 

 0,5 mm. long, somewhat paler* (Gleason, 1913, p. 316).
