be suspended near the glass should be preferred. They may be treated 

 like the smaller Odontoglots, as Od. Rossii and Od. Cervantesii during 

 the summer months, but they should be removed to the intermediate 

 house for the remainder of the year. 



The disappointing experience of the past twenty years in the cultivation 

 of the species now comprising the sections Huntleya, Bollea and 

 Warscewiczblla forbids the formulating of any course of treatment for 

 them. Doubtless several causes have combined to bring about the 

 failure to establish this fine group of orchids in the glass-houses of 

 Europe, but none more so than the withholding of reliable information 

 respecting their geographical station and their environment in situ. 

 All attempts to cultivate them hitherto have been purely empiricisms, 

 and even if the climatic and other conditions cannot be approximately 

 imitated artificially, yet it must evidently be in the interests of importers 

 and collectors to impart such information they possess as may tend in 

 any degree to assist the cultivator.

Zygopetalum brachypetalum. 



Pseudo-bulbs ovate-oblong, compressed, 2 — 2| inches long, ribbed and

 more inches long. Scapes as long as the leaves, loosely racemed, 

 7 — 10 flowered ; bracts foliaceous, ovate, acute, slightly inflated, about 

 an inch long. Flowers 2 J inches across vertically ; sepals and petals 

 uniform, narrowly oblong, acute with margins more or less revolute, 

 brown tinged with green towards the base ; lip broadly clawed, 

 expanding into a sub-orbicular emarginate blade, light mauve, ahnost

A very handsome species flowering in mid-winter. It was exhibited 



by M. de Jonghe, of Brussels, at a meeting of the Horticultural 



Society of London on December 6th, 1848, when it received an 



award. In the report of the meeting published in the Society's 



Journal {loc. cit. supra) it is stated that this species was originally 



brought into notice by Mr. Waterhouse, of Halifax, in the year 



1840 and is little known. M. de Jonghe informed Dr. Lindley 



* Bot. Keg. XXX. (1844), misc. 5 is iiuoted by Reichenbach but we do not find it there.
