sentation of this plant, and the specimen in Sir Wm. Hooker's 

 herbarium agrees very well with it, except that the leaves are 

 generally more rounded at the summit, and deeply emargijiated ; 

 but it agrees in all its other characters. The leaves are 3^ inches 

 long, 2^ inches broad, on a petiole scarcely 2 lines in length ; the 

 internodes are 1 inch distant, and the raceme is 2 inches in 

 length, on the elongated termination of the branch. 



2. Icacina Mauritiana, n. sp. ; — arbor 7-orgyalis, ramulis glabris 

 foliis oblongis, utrinque acutis, apice acuminatis, glaberrimis, 

 subtus ferrugineis, margine revolutis,petiolo subtenui; panicula 

 terminali folio longiore, pluriflora, ferrugineo-pubescente, flo- 

 ribus albis, odoratissimis. — Mauritius ; v, s. in herb. Hook, 



This is a tree 40 feet in height, growing near Colville Bridge ; 

 its leaves are 2^ inches long, 1^ inch broad, on a somewhat slen- 

 der petiole half an inch in length ; its terminal panicles are about 

 2 inches long. It appears to me referable here, rather than to 

 ApodyteSy because of the induplicated apex of its filaments, and 

 the form of its anthers, which are shorter, more ovate, and less 

 bifid than in that genus. 



3. Icacina grandifolia; — foliis cuneato-oblongis, apice obtusis, 

 infra medium attenuatis, utrinque glaberrimis, concoloribus, 

 multinerviis, margine undulatis, petiolo brevi crasso canali- 

 culato; panicula terminali laxe ramosa, ramis longe nudiusculis, 

 apice floriferis, multiflora, folio longiore. — Madagascar ; v. s. in 

 herb. Hook. (Lyall). 



This is a veiy distinct species, remarkable for the large size of 

 its leaves, which are 6 inches long, 2- inches broad, on a petiole 

 only ^ of an inch in length ; the terminal panicle is 8 inches 

 long, with its virgate branchlets 4 to 5 inches in length, which 

 are ramified towards their extremity and bear numerous small 

 pubescent flowers*.
