 No. 98. 



A species rarely seen in British gardens, and of whose origin 



scarcely anything appears to be known beyond the simple fact that 



it was first discovered by Hartweg in woods near Pasto in southern 



Colombia in 1842. We are indebted to Mr. O. 0. Wrigley for 



materials for description. 



On. raniferum. 



Pseudo-bulli.s clustered, oblong, 1 — 2 inches long, tapering upwards, 

 compressed, furrowed, diphyllous. Leaves linear, grass-like, 5 — 8 inches 

 long. Scapes as long as the leaves, sparingly branched, many flowered. 

 Flowers small but showy, bright yellow, the crest of the lip orange- 

 red ; sepals and petals reflexed, oblong ; lip three-lobed, the side lobes 

 linear-oblong, spreading, the front lobe broadly obovate with the anterior 

 margin obscurely crenulate ; crest large for the size of the flower, 

 consisting of an oblong obscurely bipartite cushion curiously tubercled. 

 Column wings very narrow.

First introduced from Brazil in 1837 by Mr. Knight, our predecessor 



at the Eoyal Exotic Nursery, and shortly afterwards found by 



Gardner on the Organ Mountains, whence it has since been occasionally 



imported with other orchids. It was aptly characterised by Sir "W. J. 



Hooker as "sb sprightly little orchidaceous plant." The specific name, 



a fanciful one, meaning " frog-bearing," was suggested by the curious 



form of the crest which somewhat resembles the figure of a frog 



couchant. We are indebted to Mr. F. W. Moore, of Glasnevin, for 



materials for description. 



On. reflexum. 



Pseudo-bulbs ovoid, 1^ inches long, compressed, mono-diphyllous.

 straggling, 24 — 30 inches long, pale green mottled with dull crimson,
