60. Triumfetta grandifloraj Vahl, De Cand. Prodr. vol. i. p. 508. — T. polyandra, Flor. Mex. 
ic. ined. ! Sierra Madre, near the village of Santa Lucia. 
Geographical distribution: Dominica (Imray!), Peru (Mathews, no. 2080!), Mexico (Hartweg, no. 
448 ! Jurgensen, nos. 9G0 and 282 ! or 882 ?). The leaves of Hartweg's specimens are covered with short 
tomentum ; those of Imray and Jurgensen but sparingly furnished with hair, and those of mine almost 
glabrous. The fruit also is either glabrous or hairy in various degrees. 
61. Triumfetta j9cmcM/«^(7, Hook, et Am. Bot. Beech, p. 279. Talisco (Lay and Collie!). 
62. Triumfetta dumetontm, Hook, et Am. I.e., non Schlecht. Talisco (Lay and Collie!). 
The specimens upon which the latter two species were founded are very imperfect ; those of T. panicu- 
lata being in fruit, and almost without leaves, those of T. dumetorum in flower only. To me they look as if 
they belonged to one and the same species.
