lip twice as long as the lateral sepals, white or greenish with deep purple base 
and lobes, or purple and streaked with paler lines (Dalzell) disk with 3 large 
calli. Macrae’s Ceylon specimen is like the Malabar plant. A. Richards’ figure of 
Birchea teretifolia is a very bad one. Rheede’s figure in xii. t. 5, on which Linnæus 
Epidendrum tenuifolium (Cymbidium, Willd.) was founded, is not a Luisia, the leaves 
are grooved, and spike very different. 
10. L. volucris, Lindl. Fol. Orchid. 1; stem stout, leaves 3-5 in. 
stout, lateral sepals cymbiform with an acute dorsal wing, petals 2—4 times 
as long 1-1} in. linear dilating to the rounded tip, hypochile oblong with 
incurved basal auricles, epichile as long much broader ovate-cordate obtuse 
fleshy. Walp. Ann. vi. 619. 
SIKKIM HIMALAYA, J. D. H. Enn Mrs. and SILHET, Lobb, J. D. H. & T. T. 
? Chittagong Hills, Zc. in Hort. Calcutt. 
Stem 6-10 in., internodes 4 in. Rachis of spike in., very stout. Petals 
and sepals very pale yellow-green; lip dark purple, epichile hardly cordate (as 
described by Lindley). Capsules 1 in.—Flowerless specimens closely resemble 
L. teretifolia. In the drawing of the Chittagong plant the stem is slender, the in- 
ternodes are lj in. and leaves 7-9 in., the petals not dilated at the tip, and the 
epichile of the lip green and grooved. 
ll. E. antennifera, Blume Rumph.iv.50; Mus. Lugd. Bat. i. 64; 
stem stout, elongate, leaves 3-4 in., rachis of spike very stout 3-1} in., 
petals linear 4 in. long twice as long as the cymbiform sepals, lip cuneately 
oblong, epichile hardly distinct from hypochile which has a broadly 
2-auricled base. Reichb. f. Xen. Orchid. i. 265, t. 78, f. 2. 
Perak, Scortechini, King’s Collector.— DISTRIB. Borneo (Low). 
Stem a foot and upwards ; internodes 1 in. (the largest of the genus except tristis), 
as are the spikes, Flowers in Low’s drawing pale green with purple lip as long as 
the sepals; in note by King’s collector, **pale greenish white waxy inner petals 
dark blue,” possibly the dark blue is meant for the lip. The form of lip is the same 
ìn a drawing by Scortechini of the Perak plant. 
12. Ee tristis, Hook. f.; stem stout elongate, leaves stout 3-5 in., 
rachis of spike very stout 1-2 in., petals 2 in. long linear twice or thrice as 
long as the sepals, hypochile of lip quadrate base 2-auricled, epichile short 
broadly ovate-cordate grooved. Cymbidium triste, Willd. Sp. Pl. iv. 99. 
pidendrum triste, Forst. Prodr. No. 314. 
PENANG, Curtis. —DrsrRIs, New Caledonia, 
Very like L. antennifera, having the same stout habit, foliage, and thick long 
Tachis of the spike, but the lip is very different, and isas far as can be judged from the 
indifferent Specimens in Herb. Forster, identical with that of his Epidendrum triste. 
fili 13. L. Grovesii, Hook. f. ; stem very slender elongate, leaves 6-10 in. 
liform, rachis of spike very short few-fld., lowers 1 in. diam., lateral sepals 
cymbiform, petals twice or thrice as long narrowly linear obtuse, hypochile 
of lip subquadrate flat, epichile broadly cordate, column very short broad. 
EASTERN BENGAL; in the Looshai Hills, G. B. Groves (in Herb. Calcutt.). 
Closely resembles Z. filiformis, but at once distinguished by the long petals.— 
men need from two drawings of plants cultivated in Hort. Calcutta, one of a speci- 
ell Without locality, the other localized as above. The sepals and petals are pale 
vith ee the hypochile and column dark purple, the epichile pale purplish in one 
“th darker margins, greenish in the other, in both dark purple at the base.
