side acute on the other; nerves 12-15 pairs, cross-nervules few, raised ; petiole | in., 

 stout. Flowers |~i in. diam. Sepals orbicular. 



13. C. Helferi, Hook.f. ; quite glabrous except the inflorescence, 

 leaves coriaceous elliptic-lanceolate acuminate or caudate entire or repand 

 serrate base equal acute or rounded, male fl. few sessile on a short stout 

 axillary peduncle, fruit unripe long-peduncled obovoid ' finely pubescent, 

 stigmas very large dilated. 



TENASSERIM or ANDAMAN ISL4NDS, Heifer (Kew Distrib. 214). 



Branches rather slender. Leaves 3-5 by 1^-2 in., pale brown when dry, shining 

 above, nerves many pair, very slender, hardly distinguishable above from the prominent 

 lax reticulations; petiole -J in. Flowers very immature, peduncle in., stout, 

 pubescent. Sepals 4, orbicular. Stamens many ; anthers extrorse. Fruit (young) 

 % in. long. The large stigma at once distinguishes this from C. subsessilis and 

 assamicus. Male flowers not seen.

 acuminate very shortly peticled base acute, midrib and nerves prominent 

 above, nerves 8-10 pair very prominent beneath, cross-nervules finely reti-

 glabrous fringed with coarse hairs, young fruit glabrous pericarp thin, 

 stigmas 2 small hemispheric.

A small tree, branches slender, bark nearly white. Leaves 6-10 by 1^-2 in., 

 thinly coriaceous dark green when dry on both surfaces, nerves arched, lower ascend- 

 ing ; petiole -Jjj in., stout. Young fruit ^ in. diam., 2-celled; cells 2-ovuled; 

 pedicel -^ j n>) bracteate at the base. 



IMPERFECTLY KNOWN SPECIES. 



15. C. leiocarpus. Kurz in Trimen Journ. Sot. N. S. iv. (1875) 330 ; 

 a tree 30-40 ft., leaves 4-6 in. subsessile glabrous chartaceous elliptic or 

 linear-oblong subacute or obtusely acuminate, base subequal, dark green 

 when dry, nerves 6-10 pairs hardly distinguishable from the reticulations, 

 petiole T ] oin., fruit axillary solitary ellipsoid or subglobose f in. diam. gla- 

 brous obscurely 2-3-lobed 2-celled 2-seeded top rounded, stigmas minute. 



NICOBAB ISLANDS ; Kamorta, Kurz. 



16. C. calocarpus, Hook. f. ; glabrous, leaves oblong-lanceolate 

 acuminate base usually very unequal-sided, fruit from the old wood large 

 globose hoary, stigmas 2 cuneate. Aporosa calocarpa, Kurz mss. 



SOUTH ANDAMAN ISLANDS, Kurz. 



Branches (in fruiting specimen) very stout, woody. Leaves 6-9 by 2-4 in., 

 coriaceous, dull green above when dry, paler beneath, base on one side rounded, on 

 the other very acute ; nerves 6-8 pair, very slender; petiole stout, - in. Eeceived 

 from the Calcutta Gardens in 1867 under the above name of Aporosa caloaarpa, but 

 not described in Kurz's Forest Flora published in 1877. I have seen no flowers; the 

 fruits are inserted on tubercles of the very stout branches far below the leaves. 



18. CHORXOPHYXiXiUBX, Benth. 



A glabrous tree. Leaves opposite, coriaceous, quite entire. Flowers 

 small, axillary, dioecious, apetalous ; males in racemose cymes ; fern, few, 

 in sessile spikes ; disk 0. MALE FL. Sepals 4-6 membranous, broadly oblong, 

 imbricate. Stamens 4, opposite the sepals, inserted round a conical disk on
