EASTERN PENINSULA; Malacca, Griffith; Sincapore, Wallich ; Penang, Jack. 

 DISTRIB. Borneo. 



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

 ceolate, 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 probably the type of a new Tein-tiiemiaceous genus. l.ivtx 

 alternate, 2-3 by 1-1 in., elliptic, acute, coriaceous, with close patent lateral veins ; 

 petiole 1 in. Flowers from the axils of fallen leaves, t'orminir a terminal panicle ; 

 peduncle in. long, thickened upwards. Sepals 5, imbricate. Immature fruit ovoid, 

 apiculate, drupaceous, containing 2 1 -seeded cells. 



ORDER XXV. DIPTEROCARPE-flE. (By W. T. Thiselton Dyer.) 



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

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

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

 fugitive, leaving an annular sear, /-'/mctr* usually s\\eet-seente<t in lew- or 

 many-flowered axillary and terminal racemes or panicles. Jlnirt* usually 

 minute or 0, rarely larger and persistent. Clnx-ttiln- live and campanulate, 

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

 at the base or free, Stamens QO, 15, 10 or 5, hypogynous or subperigynona, 

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

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

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

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

 with 3 minute stigrnatic lobes; ovules anatropous, ^ in each cell, pendulous 

 or laterally 'affixed (solitary and erect in A/n-i*(/-n<-/<ii/m<). Fruit usually nut- 

 like, sometimes capsular and 3-valved, 1- rarely 2-seecled, 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 

 A ncistrodadus); cotyledons fleshy, equal or unequal, straight or more or less 

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

 between the cotyledons. DISTRIB. Confined (except 3 Tropical African 

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



* Calyx much enlarged in fruit, segments erect. 

 Calyx in fruit with a distinct tube.
