 stem suffruticose, flexuous, scandent ; branches filiform ; leaves 

 ovate, acute, veiny, roughish on the nerves beneath ; stipulas 

 subulate, very short ; peduncles axillary, longer than the leaves, 

 many-flowered. T? . ^. S. Native of the south of Jamaica, on 

 the higher mountains. Spreng. syst. 1. p. 413. exclusive of the

 the calyx is said to be 4-lobed and the fruit baccate and 4- 

 celled, and is therefore the Petesia Lygistum, Lin. spec. 160. 

 the Lygistum axillare, Lam. ill. 1. p. 286. t. 67. f. 2., in which 

 the calyx is also delineated with 4 lobes, and therefore also the 

 Coccocypsilum biflorum, Willd. spec. 1. p. 618.; the Fernelia 

 biflora, Rcem. et Schultes, syst. 3. p. 187. Perhaps 2 species 

 are here confused, one with a 4-lobed calyx and the other with 

 an 8-lobed calyx : having 4 of the lobes lanceolate, and 4 of 

 them tooth -formed and smaller.
