Discovered by Schoraburgk during his exploration of British Guiana, 

 1840 — 44, growing in the crevices of the granite rocks at the Rue- 

 imcru Waterfall, and on the banks of the River Rue. It was gathered 

 by Mr. Everard Im Thurm, in 1885, on the Roraima Mountain, whence 

 it was imported by Messrs. Sander and Co. in the following year. 

 The species is named in compliment to Dr. Klotzsch, an eminent 

 German botanist, and for some time Director of the Botanic Garden 

 ab Berlin. 



As we have seen no plant in flower up to the date of going to press, 

 the above description is all that we are at present able to give; the 

 sepals and petals are said to be brown, and the lip greenish brown with 

 a reddish tint superadded. Although the plant when not in flower is 

 scarcely distinguishable from Cypripedium caricinum, the nearest affinity 

 of the species is unquestionably C. Lindleyanum. 



0. Lindleyanum. 



Leaves strap-shaped, 20 — 25 inches long, and 2 — 2£ inches broad, 

 bright grass-green, pale yellow at the margin. Scapes 30 — 40 inches 

 long, pubescent, green from the base upwards, reddish along the rachis. 

 Flowers 2 — 2| inches across vertically ; upper sepal oblong, acute, 

 pubescent, undulate at the margin ; light green with alternately longer 

 and shorter longitudinal red-brown veins ; lower sepal broader, elliptic, 

 concave, bidentate at the apex, pale green with red-brown veins ; petals 

 deflexed, linear-oblong, with undulate and ciliate margins, pale green 

 with red-brown veins ; lip helmet-shaped, green with red-brown veins and 

 reticulations, the inflexed lobes broad and densely spotted with red-

This also was first discovered by Schomburgk, during his explora- 

 tion of British Guiana, on the southern slopes of the Roraima 

 Mountain at 6,000 feet elevation, in grassy swamps, along with 

 lb liamphora, Utricularia, etc., flowering in November. It was 

 rediscovered in the same locality, in 1881, by our collector David 

 Burke, who brought plants to our Chelsea Nursery in the autumn 

 of that year, but none of which flowered till January, 1886. In
