PERIPLOCA. [Periplocce sp. Linn. 



Char. Corolla rotata. Squamis 5, faucis laciniis

 Filamenta distincta. Antherce cohaerentes, dor-

Mass a pollinis apice dilatato corpusculi stigma-

 bus. 



Stigma submuticum. 



Folliculi cylindracei, divaricatissimi, laeves. Se- 

 mina comosa. 

 Habitus. Frutices saepius volubiles, glabri. Fo-

 terpetiolares. 

 Patria. Europa australis. Syria. Africa septen- 

 trionalis, et aequinoctialis.

 I have seen a fourth and very remarkable spe-
