Colombia : Triana 126 ! 



Allied to the Brazilian Psyclwfria (§ Palicourea) tahacifolia 

 Mnell. Arg., from which it differs chieflv in the oblong shape and 

 size of the corolla, with its very small lobes. Leaves ca. 16 cm. 

 X()'o cm., with stalk barely 1*5 cm. at most ; secondary veins, about 

 15 pairs ; sheath of stipules 5 mm. long, with two lanceolate prongs, 

 I'o mm. apart, over 2 mm. long, between the petiole bases on 

 each side of the stem. Main rachis of injlorescence as much as 

 30 cm. or longer ; at the base it bears one or two slender branches 

 about 6 cm. long ; for the rest of its length there are no branches 

 exceeding 1 or 2 cm., and they are ascending ; the whole inflorescence 

 is thus spicate, and ver^^ slender. The tubular flowers are barely 

 4 mm, long.
