Planta robusta, erecta, foliosa. Folia ligulata, coriacea, acuta, 
disticha. Pedunculi terminale, circiter 6 bracteae imbricatae. 
Bracteae inflorescentiae lineari-lanceolatae, acutae, circiter 1.5 
em longae. Pedunculus rhachisque sericeo-pubescens. Pedicel- 
lus et ovarium pubescentia. Sepala externe pubescentia. Sep- 
ala lateralia oblonga, 5-nervia. Sepalum dorsale oblongi-lan- 
ceolatum. Petala oblonga, obtusa. Labellum 3-lobatum. Lobi 
laterales obtusi; lobus medius quadratus, apiculatus, callus 
parvus ad basim labelli; prope apicem labelli tuberculum permag- 
num; utroque in disco callus carinatus lobis lateralibus parallelus. 
Plant robust, erect, probably 10 dm high (only upper part 
seen), leafy. Leaves ligulate, coriaceous, acute, sheathing, dis- 
tichous, about 20 cm long, up to 22 mm wide. Inflorescences 
several (as many as 6) sheathed by large, imbricating bracts. 
Peduncles rather stout, about 2 dm long, whitish-pubescent. 
Floral bracts linear-lanceolate, acute, crowded, reflexed, the lower- 
most exceeding 2 cm in length, about 5 mm wide, longer than 
the densely pubescent flowers. Lateral sepals oblong, acute, 5- 
nerved, densely pubescent on the exterior surface, 7 mm long, 
3.5 mm wide. Upper sepal oblong-lanceolate, 7mm long, 3 mm 
wide, 5-nerved. Petals oblong, or nearly elliptical, obtuse, 5 mm 
long, about 2 mm wide. Labellum 3-lobed, 6 mm long. Lateral 
lobes triangular, obtuse, from the tip to base of sinus formed 
‘with middle lobe 1.5 mm long, middle lobe subquadrate, apiculate, 
3 mm long, 4.5mm wide. Calli 4, one in the middle of the base, 
one on each side near the sinus formed by the middle and lateral 
lobes, each continued from the free forward protruding apex to 
near the base of the lip, passing into a gradually diminishing 
keel, one at the apex, a large triangular, obtuse, erect tooth-like 
callus, 2 mm high, laterally flattened with the apex slightly re- 
flexed. Column very short, free portion almost none.

Eria Vanoverberghii is near Eria longibracteata Leavitt, but is unlike it 
in the dense inflorescence, large flowers, and very different calli.
