GESNERACEAE. 
Aeschynanthus stenophylla, Ridl. 
This species was described from a fruiting specimen collected 
by Kunstler in Perak, the flowers being unknown. I obtained a 
large clump of it a year ago from the house of a planter in Sedenah, 
Johore, and it flowered in November 1909, I am therefore able to 
give a fuller account of it. The stems are tufted slender red brown. 
The lower leaves elliptic fleshy blunt an inch long and 4 inch wide, 
dull light green, they become narrower towards the apex ‘of the stem 
till the uppermost ones are linear, 2 inches long and ¢ inch wide. 
‘The flowers are terminal or occasionally lateral, solitary, borne on 
a a 4 inch long. The calyx lobes linear acuminate very 
narrow 7’, inch long. The corolla } inch long, a rather slender 
straight tube, with short. rounded lobes which hardly open, all 
cream yellow with a purple edge to the tubes. The stamens are 
hardly longer than the corolla lobes and do not appear to be pro- 
truded. The style is short 4 inch long purple, the ovary longer 
slender terete green. The plant appears to be self-fertilised, the 
tube with the stamens slipping off from the ovary and drawing the 
anthers over the stigma. 
Didymorcarpus soldanella, n. sp. 
Stem short, leaves in a rosette about twelve, oblanceolate to ob-

terminal cyme nodding. Bracts reas small linear. Calyx lobes 
linear, narrow pubescent dull red 5 inch long. Corolla cam- 
panulate oblique violet minutely sparingly pubescent, 2 inch long 
+ inch across lobes, upper ovate triangular lower lip longer, lobes 
short ovate triangular. Stamens 2 filaments short sinuate violet, 
anthers connate, reniform, vellow-white. Ovary and style ¢ vlindric
