76 NEW AND RARE MALAYAN PLANTS. 



Coptosapelta parviflora, n. sp. 



Lofty climber, nearly glabrous. Leaves elliptic rather 

 long, sharply acuminate, base cuneatc. dark shining green, 

 glabrous except for a few rather long hairs on the midrib, 

 nerves 4 prs. fine, reticulations visible on both sides, 3-5 in. 

 long 1.5 i n . wide; petiole white-hairy .3-.4 in. Stipules trian- 

 gular acute, .1 in. long. Panicle terminal 2.5 in. long in 

 flower, with thin branches, lax, sparsely white-hairy. Bracts 

 narrow, linear, lanceolate acuminate .1 in. long. Flowers 

 green. Pedicels white-hairy .1 in. long. Calyx .1 in. obconic 

 ridged, white-hairy, limb campanulate about as long with 5 

 ovate lobes. Corolla-tube cylindric .2 in. long, white, silky, 

 lobes linear, oblong, nearly as long, glabrous keeled, mouth of 

 tube white-hairy. Stamens hairy. Fruit panicle 3 in. long 

 (> in. across. Branches angled, nearly glabrous. Fruit .2 in. 

 long, globular, ovoid. 



Singapore, Bukit Timah (Ridley Mil?). Pexaxg; 

 (Curtis) Borneo; Sarawak (Beccari 2518). 



This species differs in being subglabrous and having the 

 flowers much smaller in a short terminal panicle. The fruit is 

 also smaller and quite glabrous. 



Argostemma rugosum, n. sp. 



Stem fleshy, branched, erect 4 inches or more, transversely 

 rugose as are^the petioles and midrib, hairy. Leaves very un- 

 equal, larger one oblong or elliptic, shortly acute, base rounded 

 or cuneate, unequal glabrous above, nerves hairy beneath 10-11 

 prs., reticulations conspicuous 2-3 in. long, 1-1.5 in. long, 

 petiole .2 in. long. Small leaf, lanceolate, subacute .2 in. 

 long. Stipules lanceolate acute, as long. Peduncle 1 in. or 

 less with an umbel of several large flowers on pedicels .5-75 

 in. long. Bracts at base of umbel lanceolate. Calyx-tube 

 short, campanulate, with lanceolate acute lobes, much longer,- 

 .2 in. long. Corolla .8 in. across lobes oblong, lanceolate sub- 

 acute. Staminal column shorter curved. 



Selaxgor; Gunong Mengkuang 3,600 ft. (Kloss). 



I took this at first for an abnormal specimen or variety 

 of A. spinulosum, Clarke, but in view of the greater size of 

 calyx lobes and corolla, which is longer, not shorter than the 

 staminal column, I conclude it is a distinct species. 



Argostemma nervosum, n. sp. 



Stem rather woody ascending for 8 inches, dense, hairy, 

 rather . stout. Leaves very unequal, large ones subsessile, ob- 

 long, oblanceolate, abruptly acute, narrowed to the unequal 

 rounded base, membranous above with pale hairs scattered 

 sparsely and thicker on midrib ; nerves 11-12 prs., conspicuous 

 both sides much elevate parallel and hairy beneath, reticula-
