NEW OR NOTEWORTHY ORCHIDS 
An epiphytic herb up to 15 cm. tall. Roots whitish, 
spreading, fibrous. Stems concealed by the sheathing bases 
of the elongated leaves, complanate. Leaves up to 3.5 cm. 
long, 2-3 mm. wide, gramineous, distichous, linear-oblong, 
acute, more or less hispidulous on the margin above the 
middle, jointed with the complanate sheathing base. Leaf- 
sheaths 7-10 mm. long. Peduncles arising from the stem 
near the axils of the leaves, lateral, concealed at base by the 
leaf-sheaths, 7-10 mm. long, 1-flowered. Floral bract 4-5 
mm. long, scarious, round-ovate, acute, thickened at the tip. 
Lateral sepals spreading, 7.5 mm. long, 3 mm. wide, lanceo¬ 
late, acute, 5-nerved. Dorsal sepal similar and equal to the 
laterals. Petals lanceolate, acute, 6 mm. long, 2 mm. wide, 
5-nerved, thickened and subtriquetrous at the acute tip. 
Labellum 5 mm. long, 7 mm. wide; basal half cuneate-oblong, 
2 mm. wide; apical half crescentiform, apiculate, with the 
horns of the crescent 2 mm. long, narrowly triangular, re- 
trorse and acute, minutely glandular. Disc 7-nerved. Col¬ 
umn stout, 3 mm. long. 
From Dichaea Lankesteri Ames, this species differs in 
floral proportions and in the tip of the labellum being apicu¬ 
late rather than thickened into a more or less triquetrous 
prolongation. In habit D. Standleyi resembles D. grami- 
noides (Sw.) Lindl., but is readily distinguished from that 
species by the outline of the labellum.

This species has appeared in a large collection of orchids 
found by Paul C. Standley in Costa Rica. Although there 
are slight differences in the measurements of the floral parts 
between the Costa Rican plants and the Peruvian type, 
these differences do not warrant specific separation. Or-
