9. C. mauritiana, Planch. in Ann. Sci. Nat. 3me sér. x. 307. 
Youngest parts of branchlets minutely puberulous, soon becoming 
glabrous. Leaves shortly petioled, elliptic-oblong to ovate, apex 
acuminate, mucronulate, base obtuse to roundish, generally equal, 
margin entire, 2-34 in. long, 1-13 in. wide, stiffly chartaceous when 
dry, glabrous, upper surface minutely punctulate, 3-nerved, nerves 
prominent beneath, cross-veins prominulous ; petiole 3-4 lin. long. 
Stipules ovate-acuminate, produced below the point of attach- 
ment, barely 2 lin. long, sparsely puberulous. Inflorescences axillary, 
much shorter than the leaves; fertile flowers stalked, few among 
the sessile male flowers in the upper cymes; sepals concave, broadly 
. obovate-elliptic with ciliolate margin, 1 lin. long. Ovary glabrate, 
with a ring of whitish hairs round the base. Stigmas broadly dilated 
at the apex. Drupe ovoid-acuminate, obscurely strigillose at the 
apex, otherwise glabrous, obscurely keeled, dark brown when dry, 
about 4 lin. long ; pedicels 3-5 lin. long.—Planch. in DC. Prodr. xvii.

ellipsoid, narrowing at the apex, about 7 lin. long, ribbed and 
teticulately wrinkled when dry and pale brown.—C. sp., Planch. in
