spur. It is separable from the Costa Rican C. Standley 
Ames in having broader leaves, relatively shorter scapes 
and much smaller flowers, especially the spur. 
Cryptocentrum pseudobulbosum C. Schwein- 
Surth sp. nov. 
Herba pusilla, caespitosa, pseudobulbifera. Pseudo- 
bulbi perparvi, in sicco cylindracei, apice bifoliati, vaginis 
foliiferis juventute circumdati. Folia anguste linearia, 
abrupte acuta. Inflorescentiae laterales, basales, filiform- 
es, patentes, uniflorae. Flos parvus. Sepala more generis 
basi connata. Sepala lineari-lanceolata, acuta. Petala 
anguste lanceolata, acuminata. Labellum in calcar pro- 
ductum; pars libera lanceolata, acuminata, inferne con- 
cava leviter trilobata; calcar pertenue, cylindraceum, 
obtusum. Columna perbrevis, apice concavo dilatata. 
Plant small, caespitose, 4-5 cm. tall. Roots numerous, 
fibrous, filiform, flexuous. Pseudobulbs very small, cy- 
lindric, complanate and closely striate-rugose in the dried 
specimen, bifoliate at the apex, about 7.5 mm. long, sur- 
rounded in youth by one or more pairs of leaf-bearing 
sheaths. Leaves narrowly linear, abruptly acute, up to 
4 cm. long and 2 mm. wide, conduplicate below. Inflo- 
rescences lateral, basal, filiform, spreading, with several 
close tubular sheaths, 1-flowered, the peduncle about 4 
em. long. Flower small, nervose. Sepals connate below 
as in the genus, 5-nerved. Dorsal sepal (free portion) 
linear-lanceolate, abruptly acute and apiculate, about 7.2 
mm. long and 2 mm. wide below. Lateral sepals (free 
portion) very similar to the dorsal sepal but slightly larger 
and suboblique. Petals narrowly lanceolate, acuminate, 
slightly shorter than the sepals in natural position, with 
minutely irregular margins, 2 mm. wide, 3-nerved. Lip 
produced into a long spur; free portion lanceolate in out- 
line, long-acuminate, cuneate toward the narrow base,
