174 Materials for a Flora of the Malayan Peninsula. 



Whether the other two " varieties " here described are really separable as such, 

 or whether, perhaps, they mjty not even prove to be distinct species, it is not, from 

 the material at the writer's disposal, at present possible to decide. But field- 

 botanists in the Peninsula should be able to settle the point satisfactorily for tliem- 



Var. papan, so named because each of the three gatherings has been noted as 

 bearing the Malay name Kranji papau, differs from the type only in the characters 

 noted. Its facies, owing to its broadly elliptic leaves and its conspicuously com- 

 pressed pods, is somewhat distinct, and it is rather noteworthy that all three gather- 

 ings have received the same native name, a name too that has been applied to no 

 other form. 



Var. hurong, so named because it has been said by Holmberg to be termed 

 Kranji huro7ig by the Malays, has a still more* distinctive facies owing to its pods 

 being clavate, and because the pubescence on the under surface of its leaves is of a 

 darker, somewhat brownish tint. Its leaflets too are in shape exactly like those of 

 D. amhiguum. Still it does not seem possible to treat it as representing the fruit of 

 D. amhiguum because in that tree the leaflets are almost exactly opposite and are 

 very faintiy puberulous beneath, in this they are conspicuously alternate and densely 

 pubescent beneath. Its flowers have not been sent. The name Kranji hurong, it 

 should be noted, is used in Penang as an alternative one with Kranji padie, for J).

8. DiALiDM Wallichii Prain. A tree, branclilets browD, closely 

 pubescent, slightly rugose, not lenticelled. Leaves alternate 7-8 in. 

 long; leaflets 9-11, very conspicuously alternate, oblong- lanceolate, 

 acuminate, apex acute, base cuneate, 2-2*25 in. long, '6-8 in. wide, 

 coriaceous, bright-green glabrous above, densely shortly yellowish- 

 brown-silky beneath ; leat'-rachis softly pubescent ; lateral nerves about 

 15 pairs, only visible beneath and there hardly more distinct than the 

 faint intermediate secondary venation; petiolules pubescent 1 iu. long. 

 Panicles terminal and axillary, 6-8 in. long, 3-1 in. wide, branches 2-3 

 in. long, ascending, rather flexuous, softly pubescent as is the main 

 rachis ; pedicels '1 in. long. Calyx '2 in. long, ovoid in bud, tube dis- 

 tinct, segments 5, subequal, much imbricate, broadly triangular-obtuse, 

 thinly coriaceous, reflexed after flower opens, densely greenish-velvety 

 outside, inside white, glabrous. Petals 0. Stamens 2, opposite upper 

 calyx-segments; filaments very thick less than one-foui th the length 

 of anther, connective uniformly softly pubescent. Ovary brown-silky, 

 distinctly slipitate, tapering into the slender, incurved, puberulous 

 stjle ; ovules 2. Pod obovoid 1 in. long, "75 in acioss, purplish- velvety. 

 Seed solitary, subquadrate, indented near the micropjle ; 4 in. long, 

 '3 in. across, '15 in. thick, finely longitudinally striate. JD. platysepalum
