Very similar to 4. venenata, but the leaves are more coriaceous, always more or 
less pubescent beneath, and much fewer in a whorl, with usually long (sometimes 
i in.) subulate interpetiolar glands; the follicles are longer (4-7 in.), more slender, 
straighter, and sessile; the seeds are smaller and narrower.—B. Sebusii, Van H. & 
Muell. Argan., is founded on Griffith's Bhotan specimen, in which the leaves and 
flowers are those of A. neriifolia, but the pods, which are separate, belong to A. 
venenata. 
Sror. IIT. Dissuraspermum. eaves with distant nerves, Corolla- 
lobes overlapping to the right. Disc annular. Fodlicles long, slender, cylindric. 
5. A. macrophylla, Wall. Cat. 1648; leaves 6-12 in. oblanceolate or 
elliptic-lanceolate obtusely acuminate pubescent or glabrous beneath, nerves 
16-20 pairs, cymes numerous large terminal sessile or peduncled with slender 
spreading many-flowered branches, corolla-tube glabrous throat villous. 4. DC.

Philippine Islds. 
Leaves thinly coriaceous, 21-3 in. broad, shining above, rather paler beneath ; 
nerves spreading, about 3 in. apart; base narrowed into a stout petiole 3-2 in. long. 
Cymes copious, lax, pubescent; bracts 0; flowers small. Calyx campanulate, 
lobes short obtuse. Corolla-tube } in., mouth contracted; lobes rounded, pubescent, 
thick. Disce annular. Ovary ovoid, acute, glabrous. follicles very numerous, 
slender, pendulous, 12-18 by i in., terete, membranous. Seeds slender, 4 in. long. 
6. A. angustifolia, Wall. Cat. 1650; leaves glabrous obovate or ob- 
lanceolate obtusely acuminate or obtuse, nerves 10-15 pairs, cymes numerous 
branched densely pubescent many-flowered, peduncle and branches stout, calyx 
urceolate lobes very short, corolla-tube densely pubescent throat villous. A.

SiNGAPORE; Wallich. T. Anderson. Maracca and Penance; Griffith, Maingay 
(Kew Distrib. 1066, 1067, 1070, 1070/1, 1070/2). 
A tall tree (Maingay), leaves much smaller and more coriaceous than A. macrophylla, 
always quite glabrous, with fewer nerves and longer petioles (2—1 in.) and with denser 
more pubescent cymes and flowers. Penang specimens have very broad leaves, 6-7 
by 3 in. ;

7. A. Kurz, Hook. f. ; a tree 80-100 ft., quite glabrous; leaves whorled, 4-7 in. 
long, oblong to obovate-oblong, tip retuse or rounded, base aeute or obtuse, coriaceous, 
glaucous beneath; nerves parallel, numerous, slender; flowers small, white, densely 
cymulose; pedicels short and stout; cymelets shortly peduncled, whorled, forming a 
long peduncled, glabrous axillary panicle; follicles linear. A. spectabilis, Kurz For. 
Fl, ii. 183, not of Brown.—Forests of the Andaman Islds., Kurz. 
This is obviously not Brown's A. spectabilis, which is probably closely allied to A. 
macrophylla. In Journ. As. Soc. 1877, ii. 254, Kurz says of this, “hardly specifically 
distinguishable from A. scholaris." 
8. A. GRANDIFOLIA, Miquel Fl. Ind. Bat. Suppl. 555; leaves 5-7 in a whorl, 
unequal, 12-16 by 4-5 in., narrowly obovate or oblanceolate, obtusely apiculate, 
glaucous beneath, midrib stout, nerves 20 pairs strong; petiole very stout, 2 in.— 
Singapore, 7. Anderson.— Of this I have seen only two leaves, which precisely agree 
with Miquel's from Sumatra.
