COOL ORCHID GROWING. 



borne solitary on scapes from twelve to sixteen inches high 

 several of which are produced from the ripened pseudo-bulbs 

 of the preceding season's growth, about March and April 

 They must be grown in a shady position, and be liberally 

 supplied with moisture when growing. 



A. Clowesi. — Flowers clear golden yellow, lips whitish ; the 

 sepals and petals are concave, consequently the entire con- 

 formation of the flower is globular or nearly so. This species 

 is found in Columbia at five to six thousand feet elevation. 



A. Bucheri (New Granada, 1845). — Habit like the preceding. 

 Flowers greenish-orange outside, inside they are either deep 

 crimson brown, as in the variety sanguinea, or a lighter brown 

 speckled with nankeen or tawny yellow. 



A. uniflo7'a. — ^This beautiful species was introduced in the 

 same year as A. Clowesi (18-44), and is one of the best in 

 -cultivation. Its large, sub-globose flowers are white, deli- 

 cately tinged with peach, and spotted profusely with pink 

 inside. 



A. ehurnea. — • A rare and beautiful white-flowered species, 

 which succeeds if treated as above, 



Arpophyllum. 



A small genus of evergreen epiphytes from New Granada 

 and Mexico. One of the finest plants I have seen is in the 

 collection of A. Turner, Esq., Narborough-road, Leicester. 



A. giganteum (1839). — This is a beautiful plant, the leaves 

 of which are about two feet long, and are borne on slender 

 pseudo-bulbs. The flowers are deep rosy purple — small, but 

 densely and symmetrically arranged on cylindrical spikes 

 from twelve to fourteen inches long. When well grown, the 

 plants flower freely, and form objects of singular beauty. They 

 grow freely in fibrous peat, one-third turfy loam, freely inter- 

 spersed with lumps of fresh charcoal and an abundance of 

 crocks. They like plenty of water when growing.
