NEW OR NOTEWORTHY ORCHIDS 
adnato. Columna in pedem recurvum producta. Rostellum 
obtusum. 
Epiphytic herb up to 7.5 cm. tall to the tip of the dense¬ 
ly-flowered raceme. Roots fibrous, coarse, spreading. 
Leaves 3-4.5 cm. long, up to 1 cm. wide, crowded, rosulate, 
elliptic-lanceolate, membranaceous, shining, acute, with the 
margin finely and shortly ciliolate. Scape including the 
raceme 4-7.5 cm. long, exceeding the leaves, densely clothed 
with rufous pubescence. Raceme 1.5-3 cm. long, up to 1.5 
cm. in diameter, many-flowered, with the flowers ascending, 
crowded. Bracts of the inflorescence rhombic-lanceolate, 12 
mm. long, about 5 mm. wide near the middle, acuminate, 
acute, margin conspicuously glandular-fimbriate, mid-nerve 
somewhat prominent on the dorsal surface, conspicuously 
glandular. Ovary about 6 mm. long, ellipsoidal, smooth, in¬ 
conspicuously pedicellate. Perianth about 7 mm. long, with 
the sepals and petals hardly spreading. Lateral sepals co¬ 
herent with the dorsal sepal for about one half their length, 
forming an ample tubular base which is shortly decurrent 
laterally on the ovary and narrowed upward; free portion of 
the sepals about 4 mm. long, narrowly oblong, the laterals 
conspicuously glandular along the mid-nerve on the exterior 
surface, the dorsal smooth. Petals adherent to the dorsal 
sepal, about 4 mm. long, 1.25 mm. wide above the middle, 
oblanceolate, rounded at the tip, 1-nerved. Labellum ad¬ 
herent to the lateral sepals, glandular near the tip, free por¬ 
tion about 5 mm. long, with the margins adherent to the 
column at about the middle, pandurate, obtuse, sagittate 
at the base near the point of insertion on the lateral sepals 
with the basal auricles 1 mm. wide and glandular. Column 
5 mm. long, produced at base into an upcurved foot. Rostel¬ 
lum obtuse. 
Eurystyles Siandleyi is allied to E. actinosophila (Rodr.) 
Schltr., but differs from it in the shape of the petals and la¬ 
bellum. From E. auriculata Schltr., the only Costa Rican ally, 
it differs chiefly in the details of the labellum. [Fig. 2: 1,
