A shrub or small tree. Leaves crowded at the ends of the branches, narrow ohlan- 

 oeolate, acute ; margins and midrib red. Flowers 1 in. long, pink. Styles 4 in. long, 

 distinct. 



A plant of which I have seen only specimens in fruit, collected by Maingay at Penang, 

 and described below, is probafty the type of a new Temstroemiaceous genus. — Leaves \ 

 alternate, 2-3 by 1-14 ™-t elliptic, acute, coriaceous, with close patent lateral veins ;; 

 petiole 1 in. Flowers from the axils of fallen leaves, forming a terminal panicle; 

 peduncle | in. long, thickened upwards. S^als 5, imbricate. Immature /rait ovoid, 

 apiculate, drupaceous, containing 2 1 -seeded cells. 



Order XXV. DIPTEROCARPE.a:. (By W. T. Thiselton Dyer.) 



Eesinous trees, rarely climbing shrubs. Leaves alternate, simple, quite 

 entire, rarely sinuate-crenate, with parallel lateral nerves ; stipules usually 

 smaU and deciduous, or inconspicuous, sometimes larger and persistent, or 

 fugitive, leaving an annular scar. Flowers usually sweet-scented in few- or 

 many-flowered axillary and terminal racemes or panicles. Bracts usually 

 minute or 0, rarely larger and persistent. Galyx-twbe free and campanulate, 

 or very short and adnate to the base of the ovary. Petals contorted, connate 

 at the base or free. Stamens <x>, 15, 10 or 5, hypogynous or subperigynous, 

 free, connate, or adnate to the petals, filaments short, often dilated at the 

 base ; anthers 2-celled, the outer valves sometimes larger, connective 

 often aristate or with an obtuse appendage. Ovary slightly immersed in the 

 torus, usually 3- rarely 2- or 1-ceJled ; style subulate or fleshy, entire or 

 with 3 minute stigmatic lobes ; ovules anatropous, si in each cell, pendulous 

 or laterally affixed (soUtary and erect in Ancistrodadus). Fruit usually nut- 

 like, sometimes capsular and 3-valved, 1- rarely 2-seeded, accompanied by 

 the variously accrescent calyx of which two or more lobes are usually developed 

 into linear wings. Seed exalbumous (albumen fleshy and ruminated in 

 Ancistrocladvs) ; cotyledons fleshy, equal or unequal, straight or more or less 

 plaited and crumpled ; radicle directed towards the hilum, usually included 

 between the cotyledons.— Disteib, Confined (except 3 Tropical African 

 •species) to Tropical Eastern Asia ; genera about 13, species about 170.
