ANACARBIACE^. 



58. Mangifera sylvatica, Exb., Fl. Ind. I, 644. — Prof. M i q u e 1 

 has incorrectly identified this species with M. Indica, L., from which 

 it is at once distinguished by the very different white flowers, the 

 disk, and the acuminated fruits. 



59. Mangifera Eorsfieldii, M i q., Fl. Ind. Bat. 1-2, 632, is the 

 same as M. foetida, Lour. 



60. Semecarpus acuminatus, n. sp.—ArboT giabeni- 



ma ; folia cuneato-obovata v. cuneato-oblonga, basi angustata ob- 

 tusa v. acuminata, |--1 ped. longa, petiolis glabris 1-2-pollicaribus 

 acuminata, integra, subchartacea, utrinque glabra, subtus glauca, 

 nervis tenuibus sed acute prominentibus venulisque laxis et con- 

 spicuis reticulata ; flores parvi, pedicellis 1-2 lin. longis gracilibus 

 glabris, racemulosi, paniculam terminalem ramosam gracilem et 

 glaberrimam foliis breviorem formantes ; calycis dentes lati et 

 acuti ; petala linea longiora, oblongo-lanceolata, acuminata ; discus 

 fulvo-v. flavescente-hispidus ; ovarium glaberrimum ; nux oblique 

 oblonga, latior quam alta, podocarpo carnoso ipsius magnitudinis 

 miniato suffulta. — Yery frequent in the Forests of Arracan, on 

 sandstone, up to 1000 ft. elevation ; also in Chittagong. 



61. Swintonia Griffithii, (Sw. sp., Griff, in Duch. Rev. Bot. 

 II, 330 ; Walp. Ann. I, 200 ; Astropetalum sp. 2, Griff. Not. 

 Dicot. 412). This species is very different from Astropetalum 

 sp. 1, Griff., Not. Dicot. 411, t. 565 f. 2, b-d. The leaves 

 are uniformily green and glossy, the pedicels 3 to 5 lin. long, 

 petals about 2 lin. long, while the latter, which is identical 

 with S. Schwenchii, T. et B., (in Cat. Hort. Bog. 230), has the 

 leaves underneath glaucous and opaque, the pedicels only £ to 

 1 lin. long and the petals hardly a line long. 



62. Robergia hirsuta, Exb., Fl. Ind. II, 455, (1832), is the same 

 as Phlebochiton externum, W all., in Trans. Med. Phys. Soc. Calc. 

 (1834) YII-2, 231, now referred to Tapiria hirsuta. 



GONNARAGEM. 



63. Connarus monccarpus, WA., Prod. I, 143, (non Linn.), is 

 not a Connarus, for it has a sessile follicle and glabrous panicles, 

 and may most probably be the same as Rourea mntaloides.
