oblong, 5-5.8 mm. long, up to 1.2 mm. wide, acute, slightly 
carinate on the outer surface. Petals obliquely linear, 5-5.5 
mm. long, more or less slightly narrowed toward the base, 
subacute. Labellum deeply adnate to the column; lamina 
narrowly triangular, tubular-involute in natural position, 
cordate at base, 3.8-4 mm. long, up to 3 mm. wide near the 
base when expanded. Column up to 2 mm. long, stout, 3- 
toothed at the tip with the lateral teeth prominent and por- 
rect and the middle tooth relatively short broad and dentate. 
Ovary with a small but conspicuous vesicle just below the 
flower in front. 
The plant was described from herbarium specimens. 
Epidendrum exiguum is nearly related toi?. strobiliferum 
Reichb. f., but it differs in being a very dwarf plant with 
small leaves, slightly branched stems, and somewhat larger

Epidendrum guanacastense A. & S. sp. nov. Herba 
epiphytica. Caules perlongi, arcuati, laxe ramosi. Folia 
angustissime linearia, in siccitate teretia et arcuata appa- 
rentia. Racemi terminales, perbreves, bi-vel triflori. Flores 
rigido-nervosi. Sepala lateralia oblique oblongo-lanceolata. 
Sepalum dorsale lanceolato-ellipticum. Petala lineari-ob- 
lanceolata. Labellum columnae valde adnatum; lamina 
ovata, callo basali tridentato ornata. 
Plant epiphytic, with stems (according to collectors’ 
notes) 2-3 feet long. Roots confined to the basal part of the 
stem, stout, fibrous, flexuous, glabrous. Stems apparently 
strongly arcuate, loosely branching, entirely concealed by 
imbricating tubular sheaths of which the lower and those 
among the scattering roots are represented by fibrous re¬ 
mains and the others are leaf-bearing. Leaves very narrowly 
linear, appearing terete in the dried plant due to the con- 
duplicate sides, up to 12 cm. long and 6 mm. wide at the
