Pappi setae intcriores persistentes, numero 40, tenues, 

 filiformes, pallide brunnese, quam exteriorcs minutissimse 

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

 corollse, sensim dilatato, glandulis nonnullis instructo, limbi 

 laciniis apice subtiis papillosis. Antlierae 1,6 mm, longse, ligula ^g 

 long, antherse, 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. 

 albicaidis Pers. But the scales of the involucres are ver^^ differ- 

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

 glabrous. Structurally, it comes very near to F. gnaphalifolia 

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

 only slightly so to V. albicaulis.

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

 scription it seems to be a good one, coming near to V. me^nbra- 

 nacea, from which it differs in having the leaves »closely gra}^- 

 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).
