A SCIENTIFIC EXPEDITION TO TEMENGOH. 61 
Ps. ascendens, un. sp. 
Stems slender climbing and rooting on tree trunks, 
above pubescent. Leaves ovate subacute base rounded 
1-14 inch long 3-1 inch wide, above glabrous, nerves 
depressed, beneath pubescent especially on the nerves, 
nerves slender 7 pairs meeting within the margin in 
loops, petiole very short § inch or less long pubescent. 
Stipules very small pubescent caducous. Cymes lax 
on slender peduncles pubescent, peduncles | inch or less. 
Whole cyme about 14 to 2 inches long, branches 
spreading. Bracts lanceolate pubescent, g inch long. 
Bracteoles linear smaller. Pedicels pubescent $ inch 
long. Calyx tube short campanulate, 5 lobed lobes 
acute. Corolla § inchlong, lobes 5 oblong obtuse pu- 
bescent outside, as long as the tube inside the tube, 
mouth woolly. Anthers 5 subsessile. Fruit 4 inch long 
_ elliptic narrowed at the base and slightly often towards 
the tip with 8 grooves. 
-Temengoh, creeping on tree trunks low down. 
This plant resembles closely one distributed from 
the Buitenzorg gardens by Koorders under the number 
29375b and the name Psychotria ? laxiflora, Bl., but 
this plant is quite glabrous. Now Ps. laxiflora is 
described by Blume as having the leaves glabrous and 
narrowed at the base which neither the Temengoh, nor 
Koorders’ plant has. In the Materials, King. and 
Gamble describe P. laxiflora, Bl., as having 4 sepals, 
corolla lobes and stamens. The number of parts is not 
mentioned in Blume or Miquel’s description, and 
Koorders’ plant has 5 calyx lobes on the fruit. I have 
seen no plant corresponding to Blume’s: and Miquel’s 
descriptions in the Malay peninsula and the specimens 
Singapore (Ridley 13 and 4828), given in the Materials 
as Ps. laxiflora, Bl., are both Gaertnera viminea and 
part of the description of: the Psychotria at least
