196 ORCHIDACEM 



narrowed abruptly into the short petiole. Flowers yellow, in 

 graceful ± 1 dm. long racemes. Bracts 4 mm. long, narrowly 

 lanceolate. Pedicel and ovary slender, 7 mm. long. Lateral 

 sepals triangular-lanceolate, 8-9 mm. long. Upper sepal oblong- 

 lanceolate. Petals oblong-ovate, 7 mm. long, about 3 mm. wide, 

 3-nerved, the outer nerves branching. Labellum entire, ovate- 

 oblong, 4.5 mm. long, about 2 mm. wide at base, 3-nerved, the 

 lateral nerves branching, bicallose or bilamellate near the base. 



The material on which my determination of E. ovata is based 

 agrees with the type in Lindley's herbarium at Kew, and with the 

 specimen in the British Museum collected by Cuming, no. 2065. 

 The latter specimen Ridley referred to E. retroflexa Lindl. and 

 Reichenbach f. to E. ovata Lindl. E. ovata is closely allied to 

 E. retroflexa Lindl., from which it appears to differ mainly in its 

 more oblong labellum and less lanceolate leaves. E. Elmeri Ames, 

 which is a closely allied species, has shorter, broader leaves and 

 much smaller flowers. E. ringens Reichb. f ., also from the Philip- 

 pines, is another species closely related to E. ovata and E. Elmeri.

The type specimen of Eria polyura in Lindley's herbarium at 

 Kew, which consists of two racemes taken from the plant figured 

 in Edwards's Botanical Register, agrees perfectly with the material 

 on which the above determination is based. On the same sheet 

 with Lindley's type of E. polyura is another specimen, fragmen- 

 tary and with only one leaf, which was distributed among Cuming's
