122 Dr. Jack'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 ; Jilaments 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 overlapping each other. Radicle superior, 

 oblong. 

 Obs. This singular plant belongs without doubt to the family of 

 the ApocynecB, 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.
