tricuspidatus (Reichb.f.) Kriinzl., of Costa Rica. How- 
ever, it differs from that species in the short inflorescences 
which are always exceeded by the leaves; the elliptic 
(instead of obovate) lip which is not strongly deflexed at 
the base and which is only slightly retuse instead of being 
bilobulate at the apex; and in the shape of the callus at 
the extreme base of the lip. The two species are similar in 
their capsules which are beakless and strongly 38-winged. 
The flowers, except tor being smaller, are almost iden- 
tical in appearance with those of L. oncidioides Knowles 
& Weste. However, the lateral sepals are entirely free 
at the base, whereas those of J. oncidioides are united for 
about one third their length. Vegetatively, these two spe- 
cies are very different. The inconspicuous pseudobulbs, 
short and stubby inflorescences, and beakless strongly 
3-winged capsule of L. Johnston immediately separate 
it from L. oncidiordes. 
It is of interest to note that the descriptions we have 
seen of the genus Leochilus fail to describe adequately 
the fruits of the various species included in that genus. 
The capsules are usually briefly described as *‘ellipsoidal, 
beaked.*’ They are actually rotund-trigonous to ellipsoid, 
strongly beaked or beakless, and with or without promi- 
nent wings. 
We take pleasure in naming this species in honor of 
its discoverer, John R. Johnston.
