 in. broad, with very prominent midrib and lateral veins (•§— 1 in. apart) below; 

 petiole i in. Branches terminating in long, leafless, subflagelliform extre-

 alternate, prominent nodes, minute sessile fascicles of abortive (leaf or

9. ? G. ? Smeathmanni, Oliv. Branches terete. Leaves coriaceous, 

 petiolate, broadly ovate-oblong, shortly cuspidate, rather obtuse at the base, 

 penniveined and reticulate, about 6-8 in. long, 3 in. broad ; petiole \ in. 

 Flowers small, pedicellate, in crowded fascicles from thickened multibracteo- 

 late axillary pulvini; pedicels filiform, about equalling the petioles.?—

The authors of this species suggest the possibility that it may be identical with Xantho- 

 chjmus guineensis of Don. 



5. XANTHOCHYMUS, lloxb. ; Benth. et Hook. f. Gen. PI. i. 175. 



Flowers polygamous or dioecious. Sepals 5, imbricate. Petals 5. Malefl.: 

 Stamens in 5 narrow oligandrous phalanges, inserted into or between the 

 lobes of a fleshy disk. Female or hermaphrodite fl. : " Staminodia in 5 pha- 

 langes, alternating with as many glands. Ovary 3-5-celled, with a subsessile, 

 discoid, entire or radiately 3-5-lobed stigma ; ovules solitary. Fruit baccate. 

 Embryo thick, fleshy, with inconspicuous cotyledons." — Trees, resembling 

 the preceding genus. Flowers axillary or terminal, fascicled or racemose. 



A small genus, closely allied to Garcinia, and scarcely differing, except in its pentamerons 

 symmetry, confined also to the tropics of the Old World. The following species is a doubt- 

 ful member of the genus, as I have seen only male flowers : — X. guineensis., Don, Gen. ojs . 

 i. 621, of Sierra Leone, it is impossible to identify from the brief indication given. 



1. X.? quadrifarius, Oliv. A small tree. Leaves submembranous 

 or thinly coriaceous, oblong-elliptical, rather obtusely apiculate, more or less 

 rounded to the petiole, with distant, obscure, lateral veins; 3£-5 in. long, 

 H-2 in. broad ; petioles |-| in. Male flowers numerous, in terminal um- 

 bellate racemes, l|-2 in. diam., the common peduncle lengthening out t 

 1 in. or more, tetragonous, closely pitted on each face with the sockets o 

 the articulated fallen pedicels of |-f in. Sepals subequal, ovate, obtuse. 

 Petals elliptical or obovate, much exceeding the sepals. Stamens in narrow- 

 linear phalanges, each of 8-10 stamens, equalling or exceeding the petals, 

 from between the lobes of a papillose cavernous disk ; filaments shortly in* 5 

 above ; anthers minute, didymous.

A remarkable plant, for the female flowers of which it is very desirable that search siio 

 be made.
