CI. 14.] RHAMNI. 183 



Austr. 22. The Aestivation of their Calyx is imbri- 

 cated. Seeds tunicated. 



Sect. 3. Stam. opposite to the Petals. Fruit dru- 

 paceous. Mayepea Aubl., Samara, Rhamnus, fig. 266, 

 Ziziphus, and Pa liar as. 



Sect. 4. Stam. the same. Fruit 3-lobed. Colletia 

 Commers. Lam. Illustr. t. 129, Ceanothus, Hovenia 

 Thunb., and Phylica. 



These 2 last Sections chiefly contain Mr. Brown's 

 true Rhamnea, the Aestivation of whose Calyx is val- 

 vular, and it's tube coheres more or less with the Ger- 

 men. He admits here Rhamnus, Ziziphus, Paliurus, 

 Ceanothus, (from which last, as he justly says, Poma- 

 derris is hardly distinct,) Colletia, Cryptandra Sm., 

 Phylica, Gouania, Ventilago Gaertn., and probably 

 Hovenia. 



Another Order of Mr. Brown's, named Buttne- 

 riacece, Bot. of Terra Austr. 8, is allied on one hand 

 to Rhamnece, on the other to Malvacecc, To this be- 

 long Abroma, Commersonia, Lasiopetalum, fig. 267, 

 and several unpublished genera. 



Sect. 5. Akin to Rhamni, generally with a superior 

 Germen. Brunia, and Thunberg's Bumalda. 



Sect. 6. Akin to Rhamni, but differing in their in- 

 ferior Germen. Gouania, see Sect. 4, Plectronia, 

 CarpodetusForst, Ancuba Thunb., Glossoma Schveh. 

 792 (Votomita Aubl.).
