Tribe Vitice^e. 



This group is readily distinguished from the two preceding ones 

 by the cymose inflorescence. The ovarium is that of Durantete, and 

 in some genera there is the same tendency of the calyx to augment 

 after the flowering. The habit is often arborescent, and compound 

 leaves are not uncommon ; but no accurate circumscription of the 

 tribe can be attempted until the numerous heterogeneous plants col- 

 lected under Clerodendron, Premna and Callicarpa, and many little 

 known Asiatic genera, shall have been more carefully examined.

I have received from Sir W. J. Hooker specimens gathered in 

 Trinidad by Mr. Lockhart, answering precisely to Vahl's description 

 and figure. M. Schomburgk's specimens agree with them in every- 

 thing but the points noted above. 



79. Vitex umbrosa. Sw. Fl. Ind. Occ. ii. p. 1076. — On the Essequibo. 

 Schomburgk. 



A single specimen answering perfectly to Swartz's description, 

 except that the panicle is rather shorter than the leaves.

 burgk, n. 772. 



Near JE. data, Swartz ; but it does not appear to be a climber, 

 the leaves are narrower at the base, the panicle is more glabrous, 

 looser and fewer flowered, and the colour is, according to Schom- 

 burgk, white, not yellow.
