1 72 RODKIGUEZlA. 



A very pretty species originally discovered by the German botanist 

 Poppig in 1830 on the Andes of Peru, near Maynas,* growing on 

 calabash trees (Grescentia Ciijete), and which after his return to 

 Europe he dedicated to Mr. Bateman, who had paid him a visit at 

 Leipzig where he had been appointed Professor of Botany. Nothing 

 more was seen or heard of it till 1866, when it was re-discovered 

 by Wallis near Moyabamba, it was supposed, and who sent it to 

 M. Linden's horticultural establishment at Brussels. It was first 

 cultivated in England by Bishop Sumner at Farnham Castle, and 

 Mr. Wilson Saunders at Hillfield, Reigate. 



R. Candida. 



Pseudo-bulbs about the size of a walnut, slightly compressed, mono- 



phyllous. Leaves oblong-lauceolate, acute, 4 — 6 inches long. Eacemes 



as long as the leaves, pendulous, 4 — 7 flowered. Flowers fragrant, of 



semi-transparent texture, 2 — 3 inches across vertically, white with a 



bright yellow longitudinal bar on the lip that is sometimes rayed ; the 



dorsal sepal obovate-oblong, emarginate ; the lateral two much smaller, 



connate to two-thirds of their length and embracing the spur of the 



lip at their base ; petals obovate, obtuse ; lip with a channelled claw 



and obcordate, emarginate blade, multi-lamellate on the disk, the lateral 



lamellae divergent. Column clavate, toothed at the apex.

Introduced from Demerara by Mr. Bateman, in whose collection 

 at Knypersley it flowered for the first time in April, 1835. It was 

 afterwards detected by the brothers Schomburgk during their 

 exploration of British Guiana on the sand hills and in the light 

 forests near the river Demerara growing upon the branches of 

 shrubs. Ever since its first introduction it has been generally recognised 

 by amateurs of orchids as one of the most beautiful of Rodriguezias 

 or Burlingtonias as it is better known in gardens. 



R. decora. 



Rhizome scandent, slender, jointed at intervals of about an inch. 

 Pseudo-bulbs produced from the rhizome at intervals of 5 — -9 inches, 

 ovoid, compressed, about an inch long with a linear-oblong, acute leaf 

 springing from the base on one side and a larger apical one about 

 6 inches long. Scapes from the axils of the basal leaves, slender, 



* This name seems to have disappeared from modern maps.
