1894, vol. i. p. 781, fig. 100. 
Under his description of this beautiful plant in” the 
Orchid Review.Mr. Rolfe has pointed out its close relation- 
ship to Selenipedium Lindleyi, Reichb. f., and a comparison 
of the figures of the flowers of the two species shows that 
the forms of all their parts are almostidentical. The most 
conspicuous differences between them are the great size and 
robustness of S. Lindleyt, which attains three feet in height, 
the length of its leaves, upwards of two feet long, the more 
numerous flowers disposed in a raceme, their colour pale or 
light green with red-brown nerves, and the absence of the 
two opposite contiguous white tubercles in the margin of 
the inflexed portions of the lip. The habitats of these two 
species are widely apart, S. Lindleyanum being (as far as is 
known) confined to Guiana, where it was discovered by 
Sir Robert Schomburgk in grassy swamps of the interior 
half a century ago, whereas 8. Sargentianum is a native of 
the Pernambuco province of Brazil, no doubt from its 
mountainous interior, and probably from the chain of the 
Cariris or Tabatinga, which are clothed with forests. Of 
Novemser Ist, 1895.
