This species is peculiar among the true Vandas from the 
absence of a spur, a mere depression representing it. It might 
be better to exclude it from the genus. It has, however, been 
successfully crossed here with V. teres, Lindl., a spurred species 
producing a remarkably handsome offspring, V. x Miss Joaquim. 
VANDA TERES, Lindl. in Wall. Oat., n. 7324. 
Hab. Siam: Tonka (Native collector) ! 
This locality is hardly within our borders; I record it as the 
most southern known for the species. 
RHYNCHOSTYULIS, Blume. 
R. retusa, Blume, Bijdr., p. 286. t. 49. 
Hab. Southern Siam: C. Curtis! 
I have it on Mr. Boxall’s authority (himself the introducer of 
the species) that Saccolabium littorale, Reichb. f. in Gard. 
Chron. (1881) 1. p. 198, is the same plant as Rhyncostylis 
retusa, Blume. 
R. gigantea, Ridl. Saccolabium giganteum, Lindl., Gen. et 
Sp. Orch., p. 221. 
Hab. Singapore: at Selitar, on a big Dipterocarpous tree ! 
Pulau Aor, an island off the east coast of Johore 
(native) ! 
This is commonly imported by natives from the more distant 
islands, Tambilan, &. A single plant found with Dendrobium 
Dalhousieanum, Wall., in Singapore, is the only known record 
from the peninsula. 
The white flowered form is as commonly introduced here as 
the pink-spotted one. 
TRICHOGLOTTIS, Blume. 
T. retvsa, Blume, Bijdr., p. 360. fig. 8. 
Hab. Selangor : Kwala Lumpur, on limestone rocks, Kelsall ! 
Pahang: Kota Glanggi, caves ! 
Siam: Pulau Rendong (native dealers !). 
Also occurs in Borneo! and Java. 
This plant agrees with Blume’s figure and description as far 
as they go. It is a tall, stout plant, about 3 feet in length,
