J. Day, Esq. We have also imported a large mass last year at 
the Hamburgh Botanic Garden. 
[thizome stout, green, with many articulations, and many 
roots scandent or creeping. Adventitious roots filiform, flexuose, 
sometimes branched, torulose, much bent. Pseudobulbs at small 
intervals, ovoid, scarcely ancipitous, sometimes subtetragonous, 
very much thickened when destitute of leaves; sheaths of lower 
part triangular-acute. Developed leaves three or four, with 
ligulate-apiculate or cuneate-ligulate acute, or cordate-triangular 
blades, the line of the middle nerve keeled on the under side. 
Younger pseudobulbs terete, with brownish sheaths; older pseudo- 
bulbs finally with very obscure marks of the fallen leaves. Flower- 
stalk racemose or paniculate, equally whitish velvety from simple 
tubular papille (fig. 11), like the bracts outside, the stalked ovaries, 
and the sepals (outside). Hither some bract-like sheaths at the 
base or none. Bracts triangular, three-nerved, scariose, much 
shorter than the pedicellate ovaries, or reaching over half their 
length. Sepals triaugular-acuminate, the lateral ones connate at 
their base. Tepals linear-lanceolate, one-nerved. Lip cuneate- 
rhomboid acuminate, obtuse-angled on both sides, the three 
middle veins thick from the very base to the disk of the dilated 
part, confluent at the very base, and having there at each side a 
small tooth. Column trigonous, a little compressed. Androcliniwm 
ascending. ostellum semilunate. Stigmatic hollow semilunate. 
Anther depressed, with the locelli oblique. Sepals outside copper- 
coloured, inside the. same, or more greenish, or totally green. 
Tepals, lip and column greenish yellow. The buds are bent in a 
queer manner with the ovary, and have, no doubt, suggested to 
the late Dr. Lindley the name of “Avicula,” they having a 
remarkable likeness to a bird’s head with a long neck. 
Materials :—Living plants observed in the Saundersian, Dayan 
and Hamburgh Botanic Gardens; inspection of Dr. Lindley’s 
type; description from living plant at Reigate, 1868, and from 
fresh specimens at various times; seven herbarium specimens. 
Tab. 188.—A plant. I possess a specimen with a much better 
developed panicle. The branches of the panicle would appear 
always to ascend in the flowering state, and to bedivaricate in the 
bud state. 1, a bud, with part of rhachis +; 2, flower, front
