ginate ; peduncles axillary, longer than the petioles, racemosely- 

 corymbose. Jj . S. Native of Jamaica. Sarcomphalus, P. 

 Brown, Jam. 179. Rhamnus sarcomplmlus, Lin. amcen. 5. p. 

 395. Kuntli, nov. gen. amer. 7. p. 57. in a note. Ceanothus 

 sarcomphalus, D. C. prod. 2. p. 30. This differs from the other 

 species in the petals being helmet-shaped, stamens turned out- 

 wards, and in the disk being thicker, as well as in the leaves 

 being alternate, not approximating by pairs. This tree rises 

 generally to a considerable height ; the trunk is generally about 

 3 feet in diameter. The wood is hard, of a dark colour, and 

 close grain ; it is looked upon as one of the best timber woods 

 in the island of Jamaica. The name is derived from o-apj, crap- 

 KOC, sarx, sarcos, flesh, and ofuj>a\oc, omphalos, a navel ; resem- 

 blance in the ovary, surrounded by the disk. 

 Sarcomphalus Scutia. Tree 30 feet.
