The specimens, with unexpanded flower-buds, exactly accord with 

 the description and figure above-cited, only the leaves are mostly

This, which is also Pohl's No. 1083, has the branchlets glabrous 

 (not ferrugineous) , and the leaves are mostly broader, and obtuser 

 (or rounded, instead of tapering) at the base, than in the plant of 

 Martius, of which it appears to be only a marked variety. The 

 peduncle and the branches of the trichotomous cyme are compressed. 

 The flower-buds are unexpanded.

The species here associated have been variously referred, some of 

 them to Eugenia, others to Myrtus: but they evidently belong to 

 neither, as the full details of Plate 66, elaborated with extreme care 

 and ability by Mr. Sprague, will abundantly show. From Myrtus,
