tepals had also some small spots at their base in an oblique row. 
Fresh flowers I obtained from Mr. Linden, and those I saw in 
the beautiful Saundersian collection were very pale sulphur- 
coloured, with brown spots at the base of the column, and were 
much streaked at the base of the lp. Our artist was more 
fortunate, since he saw the colours much brighter. 
The plant was gathered near Ocana, in New Grenada, by 
Mr. Wallis; before him by Mr. Schlim, who found it in company 
with Chondrorrhyncha rosea. I have also obtained specimens 
gathered there by Mr. Blunt, sent by Mr. Low, and by Mr. Rozl, 
given by Mr. Ortgies. Wagener’s specimens are doubtful, as 
I have mentioned before. There is no doubt that the plant is 
very curious, nor that it will have disappeared in a very short 
time from all our collections. Mr. Van Branteghem, of Brussels, 
the skilful grower of cool Orchids, informs us it is very difficult 
and capricious. 
Bulbless. Roots very numerous, thick, forming a sort of nest. 
Leaves cuneate-oblong or cuneate-lanceolate, acute. Ilower-stalks 
upright or nearly so, one-flowered, with three distant sheaths, 
much shorter than the leaves. Bracts two, the lower one fertile, 
much broader and longer than the upper one, but much shorter 
than the stalked ovary. Perigone membranaceous, pellucid, very 
thin. Chin obtuse-angled. Sepals ligulate acuminate, now and 
then undulated at their margin. Tepals oblong apiculate, with 
finely toothed margins. Lip cuneate at the base, flabellato-oblong, 
three-lobed, or hastate oblong-triangular, bilobed, fimbriate and 
undulate on the whole of the margin. At the base of the lip 
stands a triangular callous wall, with two teeth on the anterior 
apex, a broader or narrower keel in the middle line, and nume- 
vous small calli outside of these. They have not been observed 
by the artist. Column clavate, bearing on both sides of the andro- 
clinium an angle (not observed by the artist). Anther-case 
ligulate, blunt at the top, acute at the base, with well-preserved 
small valves on its lower side. Pollinia ligulate obtuse, incumbent 
in pairs, the superior much longer. Caudicle quadrate. Glandule 
triangular. 
Materials:—A sketch, with analysis, made from the living 
plant, observed several times in flower, in the gardens of 
W. Wilson Saunders, Esq., and Mr. Linden; nine herbarium 
specimens, excluding those of Wagener.
