Prope Kuripan cl. Zollinger R. matutinam invenit, sed monet locum cultura immutatum. 

 Omnis diagnosis eo recedit a R, matutina, quod in hac cL Bl. monet sepala lateralia connexa, 

 quod in ilia non affert.

 ostium calcaris oblique adnati protensus. (PoUinia bina bipartita sen quaterna caudicula tri- 



angula sen Uneari subulata; glandula quadrata seu triangularis.)

 Rostellum truncatura. — ^The lip is a hollow curved blunt horn, rising from the base of the 

 column with its convexity upwards; on the convexity lies a flat yellow wrinkled fleshy tongue, 

 which seams as if it consisted of two layers; at the base the lip is concave and has on either 

 side a short truncate ear, with which it clips the column. Column is taper, short, straight, 

 with a nearly circular slope. No known genus can receive this singular plant , unless it 

 is thrown into the crowd ofSaccolabs, among w^hich however it would scarcely be sought; for 

 its thick fleshy lip is very different from the thin membrane found in that genus. Moreover 

 it is essentially distinguished by its rostel, not being extended into along beak as is the case 

 in all genuine Saccolabs and Sarcanths. As for Sarcochilus, which it is said to resemble, that 

 genus is quite different in the long narrow foot on which the lip is placed, as well as in the 

 nature of the hpe itself. — Tropical Asia."

 whether a plant, very rare in Gardens, bearing this name*' (Vanda Sulingi) „and much resembling 

 a Renanthera, is what Blume intends; but I presume not" Lindl. Folia IV. Vanda p. 7 sub
