 very short, clothed at the back with a bright red (glandular?) 

 membrane, articulated with the branch ; female flowers terminal and 

 in the upper axils, subsessile, 1 to 4 together, herbaceous-green ; calyx

5. Garcinia? (sp.). 



A glabrous scandent shrub, hard and rigid in all its parts, 

 elegant, 5 to 8 ft. high ; sap watery ; branches terete ; branchlets 

 erect-patent, cylindrical, at the insertion of the leaves piano - 

 compressed ; leaves oval-oblong, abruptly and obtusely acumi-
