sometimes. dichotomously 5-flowered, having a flower in the 
bifurcation. Calyx semi-inferior, surrounding the ovary, ovate ; 
limb 8-parted, spreading; Jacinie linear, acute, thick, rather 
incurved at their points. Corolla white, 8-petaled: petals 
nearly erect, alternate with the lacinie of the calyx, condu- 
plicate, inclosing the stamens by pairs, bifid, furnished with 
a few threads or filaments at the point, ciliated on the margin. 
Stamens double the number of the petals, inserted on the 
calyx in a double series, the inner ones shorter, erect, not so 
long as the petals, enfolded by them until the period of com- 
plete expansion, when they burst from their recesses with 
elastic force, and disperse their pollen. Anthers linear, acute, 
2-celled. Ovary contained within the calyx, 2-celled, tetra- 
sporous: ovules subrotund, affixed near the top of the cells. 
Style filiform, as long as the stamens. Stigma bifid with 
acute laciniz. Fruit contained in the persistent calyx, l- 
seeded, the other 3 ovules proving abortive. Seed at first 
ovate or roundish, with conform albumen: the embryo inverse, ~ 
in the upper part of the seed. As the fruit advances, the 
radicle is elongated, and becomes at length nearly cylindrical, 
obsoletely angled and rather acute at the point. I have 
generally found 3 cotyledons, rarely 4. 
Oss. Rumphius figure is by no means a good represen- 
tation of the plant, but his description of it is correct. It 
comes nearest to the R. cylindrica, (Kari Kandel, Rheed. 
Mal. v. 6. p. 59. t. 33,) which differs from this in having the 
radicle very obtuse, and more exactly cylindrical, and the 
peduncles generally l or 2-flowered. According to Rumph 
this species is rather rare, and is called Mangi Mangi Chenke, 
or Clove Mangrove, whence his appellation caryophylloides, 
which I have thought proper to retain, as the resemblance 
holds good in some particulars.
