Hab. in Trinidad: Lockhart (K); E reliquis Crtjeger., 

 Purd. etc. arranged by I. H. Hart a. 1888 , n. 2036 (KU, 

 orig. spec). 



The description of this new species has been made from 

 the specimens of the Krug-Urban Herbarium. The plant 

 collected by Lockhart is very badly preserved, nearly all 

 heads being discharged, without bracteal leaves. Its leaves 

 are somewhat larger than those of the type specimen, 15 

 cm long by 7 cm wide; otherwise it agrees well with it. 



V. Trinitatis belongs to a little group of species very 

 nearly related to each other. The best known of these spe- 

 cies is V. argyropappa Btjek (= V. Poeppigiana DC. Prodr. 

 p. 55, not V Poeppigiana DC. Prodr. p. 20. De Candolle 

 in his Prodromus described two V. Poeppigiana^. Buek, 

 having observed the fault, nullified the name of the second 

 species, calling it V. argyropappa. This name should be retained 

 for the species, even though the first V. Poeppigiana is now 

 referred to Piptocarpha). The other species of the group are 

 V. Miersiana Gardn. from eastern Brazil (= V. Salzmannii 

 Baker in Fl. Bras., not V. Salzmannii DC), V. virens Sch.- 

 -Bip. from Central Brazil, V. hirsutivena Gleason from Yuca- 

 tan, and two not published species, V. Friedrichsthalii Sch.- 

 -Bip. mscr. from Guatemala Columbia and V. strigosa Sch.- 

 -Bip. mscr. from Mexico. The species in question are, in fact, 

 very closely related, and might be united into one single, though 

 extraordinary variable, species. However, I prefer not to 

 do so. They look, after all, rather dissimilar, they are easily 

 characterized, and they have, moreover, their particular geo- 

 graphical ranges. The following key gives their characteristics. 



I. Outer scales very long-cuspidate. 



A. Leaves rounded at base, velvety-pubescent beneath. 

 Trinidad. V. Trinitatis.
