 Bothriochilus bellus, Lemaire, Illus. hort. III. (1856), p. 30. 



The origin of this plant is obscure. According to Lemaire (L' 



Illustration Jlorticole, loc. cit.) it was sent about the year 1852 to 



M. Verschaffelt's horticultural establishment at Ghent, by M. Devos, 



from Sancta Catherina in Southern Brazil. But Sir J. D. Hooker 



has pointed out {Botanical Magazine, sub. t. 6628), that the 



plant is without doubt, like its congeners, a native of Central 



America, as there is a specimen of it in Lindley's herbarium, 



collected by Mr. G. Ure Skinner in Guatemala. It is by far the 



handsomest species in the genus. 



0. macrostachya. 



Pseudo-bulbs globose, 2 — 3 inches in diameter, triphyllous. Leaves 



lanceolate, acuminate, })licate, 12 — 15 inches long. Scapes as long 



as the leaves, the basal portion clothed with large, ovate acute 



brownish sheaths, the upper two-thirds a crowded spike of partially 



expanded rose-coloured flowers, the colour deeper at the base and on 



the spur of the lip, and paler on the petals. Bracts linear, acuminate, 



longer than the flowers. Sepals oblong, acute ; petals obovate-oblong ; 



lip oblong, reflexed, terminating below in a bi-gibbous spur. Column 



semi-terete, whitish.

First sent by Hartweg from the Hacienda de la Llaguna, in 



Mexico, in 1841, to the Horticultural Society's Garden at Chiswick, 



and occasionally imported since with other Mexican orchids. Its 



flowering season is August — September.

 Although founded by the Dutch botanist Blume, on a terrestrial 

 orchid fPachystoma pubescensj which he discovered in Java in the 

 early part of the present century, the genus Pachystoma was 

 scarcely known to horticulture even by name till the beautiful species 

 described below — which was sent to us in 1878 — was referred to it by
