Anthurium trinerve is a native of Brazil and Guiana, in 
which countries it is not uncommon. It is very nearly 
allied to A. violaceum, Schott, but it usually has broader 
leaves than that species; the stem too is rather more robust 
and is more densely clothed with the fibrous remains of the 
cataphyllary leaves. The chief distinction, however, as 
Mr. Brown points out, is that the ovary in A. trinerve 
tapers into a conical style-like portion exserted far beyond 
the sepals; this feature is absent from A. violaceum. It is 
1o be noted that the species here described must not be 
confounded with the similarly named A, trinervium, Kunth, 
a plant totally different in appearance, with much larger, 
cordate leaves. The plant from which the figure now given 
has been prepared has long been in cultivation at Kew ; it 
flowers freely every year and fruits copiously, the flowers 
being evidently self-fertile, i
