CCELOGYNE. 29 



in 1841 ; its usual flowering season is the winter months. It has been 

 fi'equently imported since its first discovery, and there are few orchid 

 collections of any pretensions in which it is not represented, and where 

 its fragrant flowers render it peculiarly acceptable at a season when 

 comparatively few other orchids are in bloom. It is slightly variable, 

 the deviations from the original type being chiefly in the size of the 

 flowers and in the colour and markings of the lip. 



Cultural Note. — The treatment of "cool" orchids, as formulated under 

 Odontogiossum, is that which is most suitable for Triehosma. If grown 

 in the Cattleya house, the coolest and shadiest position must be selected 

 for it.

This is a noble genus including many species of great horticultural 

 merit, some of which (including Pleione) are in flower in every 

 month of the year. About fifty named species are known to science, 

 as well as others that yet remain unnamed and undescribed, widely 

 dispersed over the Indo-Malayan region, one [Gmlogyne fimhriata) 

 spreading into southern China. The Coelogynes are particularly abun- 

 dant in the valleys of the lower Himalayan zone, especially in Sikkim 

 and eastern Nepal, up to about 7,000 feet elevation, but C. (Pleione) 

 Wallichit and G. Hookeriana ascend as high as 10,000 feet. "On the 

 ascent from Darjeeling the straight shafts of many of the timber 

 trees are literally clothed with a continuous garment of white- 

 flowered Coelogynes which bloom in a profuse manner, whitening 

 their trunks like snow."* They are scarcely less common in some 

 parts of the Malay Archipelago, where they occur in moist shady 

 places on rocks and trees by the side of streams, and also on the 

 hill sides, not infrequently at considerable elevation; these Malayan 

 species belong chiefly to the sub-section Flaccid(v, and have mostly 

 dull whitish brown or greenish white flowers. 



The genus as monographed by Dr. Lindley in his Folia Orchidacea 

 is divided by him into three sections, which are adopted by Mr. Bentham 

 in the Genera riantamm nearly as Lindley left them. The first 

 section, Neogyne, includes but one species, Ooelogyne Gardeneriana,
