Nasu: Costa RICAN ORCHIDS 123 
The herbarium material of this plant brought back still had the 
old racemes attached, but all the flowers were missing, so it was 
impossible to place it satisfactorily. Fortunately Mr. Maxon suc- 
ceeded in securing some good living plants. These throve and 
came into flower in October of last year. This supplied the needed 
material for a definite determination of the plant. It was interest- 
ing to find that it belonged to the genus Zygostates, known hitherto 
only from Brazil and Paraguay, and that it was also an undescribed 
Species. Another genus is thus added to the orchid flora of North 
America. 
Zygostates is closely related to Ornithocephalus, which ranges 
from northern South America and Trinidad through Panama and 
Central America, with one or two outlying species in Asia and 
Australia. It is distinguished from Orxithocephalus by the two 
appendages near the base of the column. The structure of the 
column and the unusual lip of this Costa Rican member of the 
genus differ considerably from the same organs in other species 
. the genus, but it seems best, at least for the present, to refer it 
ere

On trees in humid forest, Santiago, wo. 105; on tree-trunk, 
Cartago, xo, 55. This interesting color-variation, in which the 
Sepals and petals are pale-green instead of white, was first noted 
in a plant that flowered in the collection of Mr. A. H. Smee, in 
England. It is a very desirable plant, as it flowers freely, and for 
along period. The contrast of the lavender of the lip with the 
pale-green petals and sepals is most effective. It also has the 
added value of a pleasant perfume.
