13. Memecylon amplexioaule, Roxb. Fl. Ind. II, 260. A shrub, 

 8-12 feet high ; branches rather slender, terete between, bat 4-angled 

 and sometimes 4- winged below the nodes. Leaves (tinged with greenish- 

 yellow when dry) sessile or nearly so, often semi-amplexicaule, ovate- 

 oblong or ovate-lanceolate, sub- acute or shortly and bluntly acuminate, 

 broadest a little above the cordate base, penni-nerved ; the main nerves 

 9-12 pairs, not prominent, interaching inside the margin ; length 3*5-6 

 in. ; breadth 1-25 in. Flowers 2 in. long, crowded in dense, axillary 

 glomeruli 1 in. or less in diameter ; their pedicels very short 

 (lengthened to '25 in. in fruit) and with minute bracteoles. Calyx 

 campanulate, truncate, much narrowed to the base. Petals sub-rotund, 

 *2 in. in diam. Fruit globose, '3 in. in diam. Wight Ic. 279. Naud.

 M. cordatum, Wall. Cat. 4100 (in part). M. coerulum, Triana in Linn. 

 Trans. XXVIII, 158 (in part). 



In all the Provinces except the Andaman and Nicobar Islands ; 

 common. 



The petals of this are white tinged with pink. The plant described by Rox- 

 burgh under the name M. amplexicaule is a Malayan one, as he distantly states. 

 The species from the South of India which has, in most of the synonyms above 

 quoted, been treated as identical with this is, in my opinion, quite distinct. It 

 has smaller and proportionately broader leaves, and the flowers, which are smaller 

 and more numerous, are in fascicles from the axils of fallen leaves. This is allied 

 to M. costatum, and like it, this has the stems often 4-winged below the node3 ; 

 the leaves are also sessile or nearly so, but they differ from those of M. costatum in 

 invariably being cordate at the base. 



14. Memecylon microstomum, Clarke in Hook. fil. Fl. Br. Ind. II, 

 557. A tree, 40-70 feet high ; branches terete, rather slender, dark 

 greyish-brown when dry. Leaves very coriaceous, sessile and almost 

 amplexicaul, oblong or narrowly elliptic, sub-acute or obtuse, the base 

 rounded and slightly cordate, very opaque, the nerves very indistinct ; 

 length 3'25-4'5 in. ; breadth 13-2 in. Flowers numerous, small, less 

 than '1 in long (excluding the exserted stamens), crowded in dense 

 axillary glomeruli, pedicels filiform. Calyx-tube infundibuliform, 

 constricted in its lower third, the mouth wide truncate. Petals pale 

 yellowish-green. Fruit large (*6 in. in diam.), globular, the persistent 

 calyx-limb small. Cogn. in DC. Mon. Phan. VII, 1147.
