identical with Tanceciwni and Colea ; whilst Periblema, DeCand., on account of its bilocular 
ovary and definite number of ovules, is altogether excluded from the order.

Tripinna tripinnata, Lour. (= Tripinnaria Cochinchinensis, Pers.), has always been 
numbered among the doubtful genera ; and unfortunately there are no specimens of it 
among Loureiro's plants preserved at Paris and London. But I do think that in all 
essential points it agrees with Colea, and may appropriately take its place near Colea 
TelfairicB, Boj., with which it corresponds in its arboreous habit, terminal panicles, and 
undulated lobes of the corolla. Loureiro does not state in his description whether his 
plant has opposite leaves ; but if the systematic position now assigned to it be correct, 
there is reason to believe that, like all other Coleas with terminal flowers, the leaves are 
opposite. Having thus united the genera Colea and Tripinna, the necessity of adopting
