290 THE ORCHID REVIEW. [OcToBER, 1903. 
discovery of several additional species in China only emphasises its essential 
distinctness. 
The first species known in cultivation was P. pracox, which was 
collected by Gibson in the Khasia Hills, and sent to the Duke of Devon- 
shire’s collection at Chatsworth in 1837. P. lagenaria, P. humilis, and P. 
maculata were introduced by Thomas Lobb, who sent them to Messrs. 
James Veitch and Sons, then at Exeter, in 1849. P. Reichenbachiana was 
introduced by Col. Benson, in 1868, and P. Hookeriana by Mr. Elwes, in 
1877. The two latter are now rarely met with in cultivation. 
Their culture is now thoroughly understood, and has been frequently 
detailed, but it may be added that P. humilis and P. Hookeriana come from 
a rather higher, and P. maculata and P. Reichenbachiana from a rather lower, 
elevation than the others ; hence the former should have slightly cooler, and 
the latter slightly warmer treatment, if possible. 
The following is a brief outline of the cultivated species :— 
P. PRECOX (Don Prodr. Fl. Nepal., p. 37. Epidendrum przcox, Sm. 
Exot. Bot., ii, t.97. Ccelogyne praecox, Lindl. Gen. and Sp. Orch., p. 49. 
P. Wallichiana, Lindl. in Paxt. Fl. Gard., ii, p. 65. C. Wallichiana, Lindl. 
Bot. Reg., 1840, t. 24; Bot. Mag., t. 4496). Discovered by Dr. Francis 
Buchanan in Upper Nepal about a century ago, and first figured and 
described by Sir James Smith in 1805. It was introduced to cultivation by 
Gibson, who sent it to Chatsworth in 1837, and was at first thought to be 
distinct, and described under the name of Ceelogyne Wallichiana. It is 
common in Nepal, Sikkim, and Khasia, ranging from 5,000 to over 8,000 feet 
altitude. C. birmanica (Rchb. f. in Gard. Chron., 1882, ii, p, 840), intro- 
duced from Burma by Messrs. Hugh Low & Co., through Mr. Boxall, is — 
believed to be a form of the same. 
P. LAGENARIA (Lindl. in Paxt. Fl. Gard., ii, p. 5, t. 39, fig. 2; Warn. 
Sel. Orch., i, t. 17. Coelogyne lagenaria, Lindl. Fol. Orch., Coelog., p. 
153 Bot. Mag., t. 5370).—Discovered on the Khasia Hills by Thomas 
Lobb, who sent it to Messrs. James Veitch & Sons in 1849. Very little is 
known about its geographical range, but it is said to be restricted to two 
localities of very limited extent. 
P. MACULATA (Lindl. in Paxt. Fl. Gard., ii, p. 5, t. 39, fig. 2: 
Coeelogyne maculata, Lindl: Gen. and Sp. Orch., p. 43; Wall. Pl. Asiat 
Rar., i, p. 45, t. 533. Bot. Mag., t. 4691).—Discovered in Nepal by Dr. 
Wallich, towards the end of the second decade of the last century, and 
introduced to cultivation by Messrs. James Veitch & Sons, through their 
collector, Thomas Lobb, who met with it on the Khasia Hills. It is also 
found in Sikkim. Its vertical range is between about 3,500 and 5,000 feet 
elevation. P. diphylla (Lindl. in Paxt. Fl. Gard., ii, p. 66. Ccelogyne 
diphylla, Lindl. Fol, Orch., Coelog., p. 15) is believed to be synonymous, and
