5. Mastixia Clarkeana, King n. sp. A tree 40 to 60 feet high ; 

 young branches slender, striate, glabrous. Leaves opposite, thinly 

 coriaceous, oblong or oblong-lanceolate, narrowed to the rounded or 

 sub-acute base ; the apex rather abruptly and somewhat bluntly acu- 

 minate ; both surfaces glabrous, the upper pale olivaceous-green, the 

 lower dull, pale brownish when dry: main-nerves 5 to 6 or 7 pairs, 

 ascending, slightly curved, impressed on the upper surface, prominent 

 on the lower ; length 3 to 4 in. ; breadth 1 to 1*35 in. ; petiole 3 to '35 

 in. Cymes terminal, nearly as long as (or sometimes longer than) the 

 leaves, pedunculate, with rather numerous many-flowered angular 

 puberulous branches : bracteoles minute, opposite in pairs, lanceolate 

 or ovate, concave. Flowers 'I in. long, sessile. Calyx funnel-shaped, 

 pubescent outside, the month with 4 deep broadly ovate teeth. Corolla 

 depressed-globular in bud. Petals 4, nearly as long as the calyx-teeth, 

 ovate-rotund, concave. Stamens 4 : anthers short, ovate-rotund, fila- 

 ments short. Disc fleshy, 4-lobed. Style short, compressed. Stigma 

 concave. Fruit unknown. 



Perak: Scortechini 98, 625, 869; King's Collector 10861. 



Var. macrophylla, King. Leaves ovate-elliptic, shortly acuminate ; 

 main nerves 7 pairs : flowers as in the typical form. 



Perak : Scortechini 10575. 



There are in Herb. Cal. specimens belonging to four distinct species of Mastixa 

 which are too imperfect to be named, and which I have been unable to match with 

 any already described species. These are as follows : — 



- (a). Two gatherings (ffyray 1234 and King's Collector 2907) of a plant collected 

 a tan elevation of from 3000 to 3400 feet in Perak which is evidently a Mastixia. 

 In their leaves these resemble M. Maingayi, Clarke, var. sub-tomentosa, King; but 

 the under surfaces are more glabrous and the main-nerves are rather more obliqne 

 than in that plant ; the young branches are moreover of a dark colour and almost 

 glabrous, while those of M. Maingayi are pale and rufescently tomentose. These 

 specimens are in fruit, and none of them has a single flower. The fruit is narrowly 

 ellipsoid, attenuate gradually to the apex, smooth, l - 2 in. long, and '4 in. in diam. 

 While the leaves suggest a relationship to M . Maingayi, the remains of the c:ilyx- 

 lobes at the apex of the fruit, which are 4-lobed, suggest perhaps a still closer 

 affinity to the tetramerous species M. Clarkeana, King. 



(b). A specimen from Penang (Herb. Curtis 919) which is in fruit only. 



(c). Specimens of a tetramerous species (in fruit only) from the Andamaus 

 with leaves otherwise like those of M. pentandra, Bl., but obscurely serrate.
