ORCHIDACE.E 



lata?, acuta?, 3 mm. longa?; bracteae ramos subtendentes ± 1 cm. 

 longa?, acuta?. Flores mediocres, carnosi, circiter 1 cm. longi. Pedi- 

 cellus cum ovario 1 cm. longus. Sepala lateralia oblongi-elliptica, 

 4 mm. longa, 2.5 mm. lata. Sepalum dorsale simile. Petala cune- 

 ato-obovata, valde obtusa, circiter 4 mm. longa, 3 mm. lata prope 

 apicem. Labellum valde carnosum, calcaratum, vix trilobatum ; 

 lobi laterales obsoleti ; lobus medius minute triangularis, acutus, 

 calcar elongatum, circiter 5 mm. longum, intus in pariete antico 

 infra lobum intermedium callo membranaceo donatum. Rostel- 

 lum in basi gynostemii bipartitum. 



In general habit similar to Robiquetia spathulata J. J. Smith, 

 but very distinct in the construction of the labellum. 



Robiquetia Vanoverbergliii is a robust plant which is rather 

 well characterized among its near allies in the Philippines by the 

 branched inflorescence and candle-snuffer-shaped labellum. The 

 structure of the column is not unlike that of Robiquetia spathu- 

 lata, but in dried specimens it is often impossible to study the 

 finer details of structure, and errors in judgment are to be ex- 

 pected. There is no posterior callus in the sac.

95. SCHCENORCHIS Bl 



A small genus of fifteen or more species, natives of Java, Su- 

 matra, Malay Peninsula, Borneo, Celebes, New Guinea, and the 

 Philippines. The genus is in part characterized by the elongated 

 rostellum produced from the base of the column. It is closely 

 allied with Sarcanthus.
