Dr. Jacx’s Account of the Lansium 
acute, broad at the base. Calyx erect, four-parted, seg- 
ments rather obtuse, margins membranaceous. Corolla, 
tube long, gibbous at the base, narrowing upwards; lobes 
of the limb ovate. Stamens four, inserted on the middle of 
the tube, incluse ; filaments very short ; anthers long, linear, 
subsagittate at the base. Style reaching to the insertion of 
the stamens. Stigma conical, with a prominent ring. Berry 
superior, ovate, somewhat flattened at the base, smooth, 
marked near the point with four prominent lines, containing 
from one to three seeds, the fourth generally abortive ; 
when cut it exudes a great deal of milky juice. Seed ellip- 
tic-oblong, exalbuminous. Embryo inverse, conform to the 
seed. Cotyledons plano-convex, the plane sides having a 
reciprocal concavity and convexity, and being a little crisped 
towards the edges; they are deeply cordate above, the au- 
riculate lobes ee each other. Radicle superior, 
oblong. 
Oss. This singular S belongs without doubt to the family of 
the Apocynee, with which its general appearance and habit 
entirely correspond. It agrees with Cerbera in having ex- 
albuminous seeds; but its ovary is simple like that of Ca- 
rissa; it will therefore hold an intermediate place between 
these two genera.
