they affect, I have made the following selection from the cor- 

 respondence, which cannot fail to possess the greatest interest 

 for all growers of Orchidaceae. 



80. STANHOPEA oculata; S 

 " This plant inhabits the higher temperatures, and 1 



should recommend for its cultivation in Europe that it should 

 not he kept in a temperature colder than 55°, or warmer 

 than 70" ; well watered from June to September every after- 

 noon ; and from October to May inclusive only slightly wa- 

 tered every evening at sundown, to resemble our dews, not, 

 it must be recollected, so heavy as people represent them in 

 Europe — the region being high, and very different to a coast 

 climate. The seasons here are the same as in England, the

 25th, 26th, and 27th of December, 1839, the thermometer

 averaged S& Fahr. and yet Oncidium leucochilum continued 

 to shoot its young stems. Flowers in February and March." 



81. EPIDENDRUM Skinnefi. 



" This plant inhabits also a middling temperature, and 

 will thrive best in a climate graduated from 5& to 70". Do 

 not put this plant in earth, but permit it to have free scope 

 for young roots and shoots, which it will throw out in 

 August." 



82. EPIDENDRUM auraniiacum. 



" Same habitat as Oncidium leucochilum, always found 

 together ; only that this plant seeks exposure, and therefore 

 is subject to greater extremes of heat and cold ; the finest 

 masses however are always found on the steep brows of rocky 

 barrancas — thus however rarely 'come-at-able.' " My speci- 

 men bore last month fifteen flowers on one stem. 



83. CATTLEYA SMnnerl 



" This plant inhabits the hot damp coasts, and will 

 require a very different treatment to any of the foregoing ; 

 it is always found on very high trees, and most difficult to get 

 at, except after a storm that may have chanced to throw down
