Eipidendrum peraltense Ames in Sched. Orch. 4 
(May 1928) 46. 
Plant very variable in size, much more so than in 
any other form of the alliance, 11 to approximately 60 
em. tall, caespitose with approximate pseudobulbs. Pseu- 
dobulbs pyriform-cylindric to broadly ovoid, 1- (rarely) 
to 8-leaved. Leaves linear-lorate to ligulate-lanceolate, 
7-41 em. long, 0.8-2.9 em. wide. Inflorescence varia- 
ble, simple and loosely few-flowered-racemose to rather 
densely compound-paniculate, shorter than or much ex- 
ceeding the leaves. Pedicellate ovary smooth or verru- 
culose to strongly muricate when mature. Flowers fre- 
quently somewhat smaller than those of var. ramonense. 
Lateral sepals elliptic-lanceolate or oblong-lanceolate, 
10.6—-19.4 mm. long, 2.9-4.8 mm. wide, acute to acu- 
minate, dorsally thickened or carinate near the apex. 
Dorsal sepal oblong-lanceolate to elliptic-lanceolate or 
oblanceolate to elliptic-oblanceolate, 11-18.8 mm. long, 
2.7-4.5 mm. wide, subacute to acuminate, thickened at 
the apex. Petals narrowly oblanceolate to spatulate- 
oblanceolate, 10-18.5 mm. long, 2.6—4.5 mm. wide, 
subacute to acute. Lip 10—-15.1 mm. long from base of 
column to tip of mid-lobe; lateral lobes triangular-lan- 
ceolate to triangular-ovate or narrowly to broadly oblong 
(sometimes falcate), asymmetric often decidedly so, more 
or less porrect when expanded, 4.1—6.1 mm. long on the 
interior margin, obtuse to broadly rounded at the apex 
which is sometimes recurved; mid-lobe transversely oval 
to suborbicular or rhombic-ovate to suborbicular-ovate 
(rarely broadly obovate or weakly 3-lobulate), 4.8—10.2 
mm. long, 5. 1—8.1 mm. wide, short-acuminate to rounded 
(sometimes with a blunt apicule) or rarely truncate at 
the apex, cuneate to rounded at the base, margin plicate
