A powerful woody climber with a stem attaining a thickness of 

 at the base, young branches, hairy with short brown hairs. Leaves 

 opposite on long petioles 3 inches long, and one-eighth of an inch 

 thick, hairy, blade orbicular-ovate, very shortly acuminate, base 

 cordate, 6 inches long and as wide, above deep green glabrous shin- 

 ing with 8 pairs of impressed nerves, beneath nerves elevate, thickly 

 covered with soft hairs, whitish, whole leaf soft membranous- Flo- 

 wers in a terminal racemose cymes, opening one or two at a time^ 

 about 10 in number on a peduncle 4 inches long pubescent. Bracts 

 ovate, acute, Pedicles half an inch long, Calyx, tubular 54 inch long 

 with 5 acute, oblong lobes pinkish, but turning dark brown as the 

 flower opens, Corolla tube one inch long and three eighths of an inch 

 through at the thickest part, shortly narrowed at the base, then 

 dilated rather abruptly with thick walls, hairy inside, limb widely 

 spreading four inches across lobes, 5 broadly ovate rounded, clawed at 

 the base, contort, each i% inch across white, mouth of tube and the 

 inner edge of each lobe yellow, Stamons in the lower part of the tube 

 at its thickest part 5 connivent, filament very short, another arrow 

 shaped half an inch long, the base prolonged into two long divaricate 

 points, the tip produced into a long acuminate point all reddish 

 yellow, Ovary conic grooved, style slender cylindric pubescent, pistil 

 oblong 5 ribbed. Fruit 2 "follicles about 12 in linear very pointed 

 smooth, seed beaked, coma 2 inches long copious." 



Ceylon rather rare, low country to 2,000 feet, Kandy, Kalutura, 

 Haduganawa. Fl, April, May, Malabar. 



I have taken the description of the fruit from Trimer's flora of 

 Ceylon. He says the corolla tube is glabrous within and only the 

 filaments hairy. However, in our plant, the tube is also hairy for 

 great part of its length. The flowers are very fragrant. The latex 

 produces very good Caoutchouc an account of which appeared in 

 Bulletin, February 1910, p. 56, under the name of Choneiuorpha macro- 

 phylla. 



The plant is well worth cultivating for its beautiful fragrant 

 flowers appearing in March, though it is not very heavily floriferous. 

 It seems to be somewhat difficult of propagation but can be grown 

 from cuttings. Our plant was obtained from the Peradeniya Gardens 

 on January, 15, 1882. C. macrophylla Don, a native of Sylhet, is des- 

 cribed by Roxburgh under the name of Echites macrophylla. Flora. 

 Indica II 13. Clarke's edition p. 246. I have seen no specimen of it. 

 From Roxburgh's description it differs from C. Rheedei in its short 

 petioled ovate entire leaves 10 to 12 inches] long and 7 to lO inches 

 wide. The tube of the corolla is gibbous immediately above the base,, 

 and the cymes are many flowered. It is reported to give a good 

 class of rubber, as all the species appear to do. 



Ch. Penangensis n. s. p. 



A stout woody climber with hairy stems. Leaves obovate, ovate 

 very broad shortly acuminate, base rounded not cordate 8-9 inches
