ANDAMAN and NICOBAR ISLANDS ; frequent in forests, Kurz. 



A large shrub. Leaves 6-8 by 2^-3|- in., usually elliptic and narrowed at the 

 ball, rarely rounded ; nerves about 12 pair, slender ; upper pair oblong-ovate, acute, 

 from -3 in. long; petiole - in.; stipules short, broad, .cusp short. Cymes quite 

 glabrous, 3-4 in. by 4-12 broad, the 2-3 pairs of branches being very long and wide- 

 spread, much divided towards the end with slender branchlets and pedicelled lax 

 white flowers; bracts at all the divisions narrowly lanceolate or the upper subulate. 

 Fruit not seen. Introduced into the Calcutta Garden before Roxburgh's time, but 

 its native country unknown till Kurz found it in the Andamans, &c. 



34. I. oblong 1 a, JBr. in Wall. Cat. 6147 A. ; glabrous, branches stout, 

 leaves petioled oblong obtuse at both ends, nerves about 12 pair, upper pair 

 smaller sessile, stipules short, cymes peduncled small short brachiate, branches 

 stout, calyx-teeth very short, corolla-tube | in., lobes oblong obtuse, mouth 

 naked. 



TENASSERIM ; at Amherst, Wallich. DISTRIB. Java, Siam. 



Leaves 3^-5 by 1-1^ in., thinly coriaceous, greenish when dry, similar and rather 

 shining on both surfaces; nerves faint; petiole ^ in.; stipules with short cusps. 

 Cymes 1 in. high by 2-3 broad ; peduncle and two pair of branches stout, the latter 

 divided at the ends; bracts and bracteoles subulate, persistent; flowers white, 

 odorous. The Java, Siam, and Tenasserim specimens are singularly alike in size, 

 colour, and form of leave*, and size and form of cymes, but the specimens are not 

 numerous. 



35. I. lucida, Br. in Wall. Cat. 6135 ; glabrous, shining, black when dry, 

 branches slender, leaves very shortly petioled elliptic-ovate or. -lanceolate 

 long-acuminate base rounded or acute, nerves about 20 pair horizontal, cyme's 

 small peduncled corymbiform few-flowered, branches slender, bracts and l>rac- 

 teoles persistent, calyx-teeth lanceolate equalling the tube, corolla-tube 1 in. 

 very slender, lobes linear acuminate, mouth pubescent, stigma short cleft. O.

PENANG, Wallich. 



Leaves 3-5 by l|-2 in., thin; nerves very slender, raised on both polished sur- 

 faces ; petiole ~_g in. ; stipules very short, cuspidate. Cymes trichotOffiously 

 branched, 1 in. long with very few branches, and rigid persistent subulate I 

 bracteoles also rigid, nearly as long as the cahx. The specimens ; ire very insuffi- 

 cient; the habit and colour are those 'of 7. nigricans, but the cnlyx^teeth, long 

 corolla-tube with pubescent mouth, broader buds, and short stigma with short, 

 recurved arms, are very different. 



36. I. nigricans, Br. in Wall. Cat. C154; glabrous or cymes pubt - 

 black when dry, branches slender, leaves petioled elliptic-oblong or -lanceolate 

 or -obovate obtusely and acutely acuminate, nerves 12-1 5 pair archod, cyiiu^

 with long cusps, calyx-teeth lanceolate or subulate acute, corolla-tube -\ in., 

 lobes slender, mouth naked, stigmas long slender arms. W. $ A, Prodr. 428;
