villous. 
Mindanao, Lake Lanao, Camp Keithley, Mrs. Clemens 1228, September, 1907. 
A species well characterized by its diffuse panicles which exceed the leaves in 
length, and thinly membranous very pale leaves. Apparently allied to Aglaia 
hexandra Turcz., but very different from that species. 
WALSURA Roxb. 
Walsura multijuga King in Journ. As. Soc. Beng. 64 2 (1895) 83; Valeton 
in Icon. Bogor. 2 (1906) 156, t. 135. 
Mindanao, Lake Lanao, Camp Keithley, Mrs. Clemens s. n., September, October, 
1907. 
The specimens from Mindanao agree almost perfectly with III E 46 and III 
F 23 of the Botanical Garden at Buitenzorg, distributed as Walsura quadrilocu- 
laris Valeton, and which Valeton, 1. c., considers to be identical with Walsura 
multijuga King.

e ramis vetustioribus oriundis, brevibus, hirsutis, paucifloris; floribus

3-costatis, triangularibus, ca. 2 cm longis. 
A tree about 10 m high, the branches brown, glabrous' the ultimate 
branehlets more or less puberulent or slightly hirsute. Leaves alternate,

lules rather densely hirsute-pubescent; leaflets pale, submembranous, 
elliptical-ovate to oblong-ovate, 10 to 18 cm long, 4 to 7 cm wide, the 
apex acute or obscurely acuminate, the base subacute to rounded or 
slightly cordate, the midrib and nerves on both surfaces somewhat hirsute, 
and with scattered hairs on the lower surface; nerves about 12 on each 
side of the midrib, prominent; petiolules 5 mm long or less. Racemes 
from the larger branches, several from the same protuberance, slightly 
hirsute, about 2 cm long, the pedicels about 1.5 mm long. Calyx about 
3 mm in diameter, somewhat cup-shaped, obscurely toothed, slightly 
hirsute. Petals 4, narrowly oblong, glabrous, about 7 mm long, 2 mm 
wide. Staminal tube cylindrical, 7 mm long, the apex 6-toothed, the 
teeth 1.5 mm long, truncate; anthers 6, alternating with the teeth, 0.8
