about six inches long, and inserting them in a pot in the same 

 manner as ordinary cuttings. This latter operation should be 

 effected just when the young growths are complete. 



T. alba, Rckb. f. — The stems of this handsome species are 

 terete, usually about two feet high, clothed throughout with 

 leaves, the lower ones, produced when the stem first begins to 

 lengthen, broad, round, amplexicaul and scale-like, the upper 

 ones also stem clasping, oblong-lanceolate acute, some six or 

 eight inches long, glaucous beneath, falling during the resting 

 season so as to leave the slender terete stems naked. The 

 flowers are produced on a short dense terminal nodding raceme 

 just as growth is finished. The sepals and petals are pure 

 white, oblong-lanceolate, acute, and nearly equal ; and the lip is 

 oblong-cucullate, rounded at the apex, where it is denticulated, 

 white, beautifully pencilled over the disk and front portion 

 with purple and lilac. The plant under consideration should 

 be potted in good fibrous peat and sphagnum, and during the 

 growing season be kept in the East Indian house ; but after 

 the flowers are faded, water must be gradually diminished 

 until it is entirely withheld, when the cool house will suit it 

 best ; care must, however, be taken to prevent its shrivelling 

 while at rest. It blooms during July and August. — Northern 

 India; Burmah.

T. Bensonise, Hook. fil. — A beautful species, with the 

 habit and general appearance of T. alba. The stems are 

 erect, leafy, terete, fascicled, from one to two feet in height,, 

 their lower parts clothed with broad roundish reflexed leafy 

 sheaths, which pass upwards into the true leaves ; these are 

 distichous, from six to ten inches long, green above, slightly 

 glaucous beneath. The flowers are large, measuring some 

 two or three inches across, and produced like those of T. alba,, 

 just when growth is finished, from the top of the stem in 

 a short scarcely drooping raceme. The sepals and petals are 

 spreading, oblong-lanceolate, two and a half inches long, open, 

 bright magenta, becoming white towards the base ; and the 

 lip is large, open, the side lobes rolled over the column, 

 magenta in front, white at the base, the central lobe oblong,
