and some other Genera of Malayan Plants. 119 
sometimes five-parted; segments narrow. Stamens four, 
sometimes five, alternate with the segments of the perianth, 
short ; anthers roundish, two-lobed. Ovary small, three-, 
sometimes four-celled ; each cell containing two ovula at- 
tached to the inner angle. Style scarce any. Stigmas three, 
sometimes four, fleshy, villous. Fruit about the size of a 
China orange, with a thick rough rind, three-valved, three- 
celled; cells generally two-seeded, partitions opposite to 
the valves. Seeds enveloped in a white juicy aril, as in the 
Lansium, &c. Embryo contained in an ample albumen in- 
verse. Cotyledons flat, foliaceous, cordate, subrotund. Ra- 
dicle superior, short, clavate. 
Oss. This is a fruit which ranks in point of taste and flavour 
along with the Lanséh, &c., but is by no means so fre- 
quently met with. The genus is most nearly allied to Pie- 
rardia of Roxburgh, with which it agrees in general habit, 
in foliage, in the mode of inflorescence, and in the structure 
of the seeds, but differs in having a valvular fruit and in the 
number of the stamens. The following description of the 
Choopa, another highly esteemed Malayan fruit, which be- 
longs to Pierardia, will illustrate the affinity between these 
two genera.
