ber, 1845. It reguires a warm damp atmosphere, and attaches 
itself by its long ash-coloured roots, either to a wall, or the 
branch of an old tree. 
** Pseudo-bulbs, or stems, one-leaved, erect, cylindrical 
when young, and almost wholly covered by a large pale brown 
scale ; but channelled and angular when old, and of a deep 
green. They are generally about four inches high, and 
three-fourths of an inch in diameter, diminishing to both ends, 
and slightly compressed at the top. Leaves oblong-lanceolate 
‘obtuse, thick and rigid, varying from four to six inches in 
length, and an inch and a half in breadth, of a rich deep 
green, and having the edges somewhat recurved. Scape 
about two inches long, round, and of a pale green, in our 
specimen two-flowered. Pedicells round, and of the same 
colour as the scape, thickening outwardly toward the flower, 
and varying from one and a half to two inches in length, with 
three small longitudinal grooves, and a minute thin acuminate 
bract at the base where it joins the scape. Flowers when 
fully expanded upwards of four inches in diameter, of a pale 
lilac colour, remarkably handsome, and sweet-scented in the 
day time. Sepals spreading oblong lanceolate acute, about 
two inches long and rather more than half an inch broad, 
a good deal recurved at the point and along the edges, so 
that the two almost meet. Petals large, ovate-oblong, upwards 
of two inches in length, and rather less in breadth, delicately 
marked and undulated at the margin, becoming of a deeper 
tint in the centre, which is somewhat raised so as to form a 
kind of midrib a little paler than the rest. Zabellum three- 
lobed, and nearly three inches long. The middle lobe is 
round and spreading, divided in the centre, and very much 
undulated and recurved at the margin, which is tinted with 
pale lilac, changing inwardly to a soft yellow colour, and 
striated with deep red lines along what may be termed 
the throat of the tube formed by the two lateral lobes, which 
curve upwards on each side, and embrace one another so as to 
conceal the column. The outside of this tube is of a deeper 
lilac than that of the petals, and beautifully veined, becoming 
compressed when the flower has been open for some time. 
Column scarcely more than a third the length of the labellum, 
hollowed out below, so as to appear two-edged, and rounded 
above, with a small round fleshy process projecting over the 
anther case, of a deep pink colour.”
