identical with TcmcBcmm and Colea ; whilst Periblema, DeCand., on account of its bilocnlar 

 ovary and definite number of oviiles, is altogether excluded from the order.

Tripinna iripinnata, Lom\ {= Tripinnaria CocUinchinensis, Pers.), has always been 

 numbered among the doubtful genera; and unfortunately there are no specimens of it 

 among Lom^eiro's plants preserved at Paris and London. But I do tliink 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 tliat, like all other Coleas with terminal flowers, the leaves are 

 opposite. Having thus united the genera Colea and Tripinna, the necessity of adopting
