consequently teretifolia. Lindley's L. irichorhka consists of three Nilghiri speci- 

 mens of Z. tereUfoUa (mislabelled Khasia Mts.),,and one fruiting Khasian specimen 

 (as indicated by Eeichenbach in Herb. Lindl.). For Ogmbid, triste, Willd., see

 epichile. Reichh.f. Xen. Orchid, i. 204, t. 78, f. 1 ; Lindl. Fol. Orchid. 3.

A more slender plant than L. teretifolia, but perhaps a variety ; flowers of the 

 same size, but with a very different lip, wliich varies a little in breadth, and in the 

 distinctness of the hypochile from the epichile. The lip is rather thin, with usually 

 strong parallel grooves or nerves, though sometimes it is very thick and fleshy when 

 the grooves are not visible (in the dried state). Cobmm very short. Capsule 

 J— 1 in. — Clarke describes the sepals green without, rose-purple within ; petals rose- 

 pnrple with green tip and base ; lip yellow at base, black -purple for f of upper part, 

 but variable. 



3. Ii. trichorhiza, Blume Mus. Bat. i. 63 ; leaves 4-6 in. stout, flowers 

 twice as large as in L. teretifolia, petals \ in. long about as long as the 

 lateral sepals, lip obovate-oblong rather longer than the sepals flat grooved 

 constricted at the insertion of the broadly ovate epichile with the quadrate 

 hypochile, column rather long. Lindl. Fol. Orchid. 2 ; Beiohb. f. X.en.

I have seen only two native specimens of this plant, a flowering and a fruiting, ' 

 from Garwhal, they bear the mss. name of L. retusa, Eeidib. f. It is the 

 only species that approaches the Flora Exotica Vanda ? irichoraiza in the size of 

 the flower and length of the column, diflering from it only in the lip not being 

 longer than the sepals, which is a very variable character. Flowers of 7^. ? triohorhiza 

 in Lindley's Herbarium closely resemble this, except in having a longer lip. A spike 

 of flowers of V. triohorhiza in Herb. Hook, is presumably from the type plant ; the 

 flowers are on slender pedicels, with the lip grooved as in hrachystaohys, but with 

 the sepals and petals narrower and more acute. Of the hairy roots of V. triohorhiza 

 described in Fl. Exot. I know nothing, but Lindley, who no doubt saw the original 

 plant, says that it has sometimes an enormous development of downy roots.

 a good deal resembles L. Grovesii.
