sparingly armed with small piickles. Leaves 6-9 in. long ; pinnae 14!-16, . 

 2-2 6 in long with piiberalous lachis ; leaflets 14-20, elliptic-oblong, apex 

 rounded or obtuse, base unequal, abruptly rounded on upper, narrow- 

 cuneate on lower side, "45 in. long, 25 in. wide, chartaceous, dark-green 

 above, paler beneath, glabrous on both surfaces. 'Racemes lax, in spread- 

 ing terminal and axillary panicles with glabrous slender angular rachis 

 and branches, 8 in. long, 4 in. across, individual racemes 3-4 in. long, 

 20-oO-fld. ; pedicels glabrous slender spreading, •4-*6 in. long. Calyx 

 glabrous, thinly coriaceou.«!, lowest sepal "25 in. long. Corolla white, '25

Andamans ; very common. Distkib. Java ; Burma. 



This species is not so closely related to P. lacerans R. Br., with which Dr. 

 Miquel has identified it, as it is to F. indicum A. Rich. (P. lacerans Wall. ; W. & A. ; 

 Wight, Ic.) of whicli Mr. Baker treats it as a vaidety. P. macropterum has l»ow- 

 ever quite glabrous flower branches, very different leaflets, and fewer and smaller 

 prickles j wliile it agees with P. indicum in length of pedicels and in style of 

 inflorescence, it has veiy different pods with a much larger wing. 



2. Pterolobium densiflorum Prain. A large climber, young 

 brandies pubescent, all parts very strongly armed with large recurved 

 prickles. Leaves 4-8 in. long, pinnae 8-16, 3 in. long, with puberulous 

 rachis; leaflets 14-16, rather narrow-oblong, apex obtuse or retuse, base 

 unequal abruptly rounded on both sides, '6 in. long, "25 in wide, sub- 

 coriaceous, dark-green, glabrous on both surfaces. Racemes dense in 

 fastiginte terminal panicles with stout subterete puberulous rachis and 

 branches ; 1"5 feet long, 1 foot across, individual racemes 150-200-fld., 

 6-8 in. long; pedicels puberulous slender spreading, '25 in. long. Calyx 

 sparsely puberulous, thinly coriaceous, lowest sepal '3 in. long. Corolla 

 yellow, '3 in. long. Pod 2 in. long, glabrous ; seed-bearing base turgid, 

 reticulate, 6 in. long, '5 in. wide, wing 'h-1 in. wide, the upper margin 

 straight thickened, the lower thin irregularly sinuately convex, the apex 

 narrowly rounded. P. microphyllam Kurz, Journ. As. Soc. Beng. XLII,

Maingay's plant here cited is the same as that of Curtis both as regards flowers 

 and frnits. The description of the leaflets is taken from the Penang plant, the 

 Malacca one at Calcutta having only bare rachises. The Malacca plant is the type
