Hab. Canton; Mr. Millett. 



We have named this genus in honour of Mr. Potts, who sent to Europe many interesting plants from 

 Canton and its vicinity. Both it and the preceding belong to the same subdivision with Isonema, Vallaris, 

 Parsonsia, and Lyonsia ; from the two last both differ by the very short filaments, from Isonema by the 

 presence of hypogynous scales or an annular disk, and from Vallaris by the filaments being simple at the 

 apex. The insertion of the stamens and many other characters readily distinguish them from each other.

1. Strophanthus divaricatus ; frutex, erectus, ramis oppositis patentissimis, foliis oppositis 

 lanceolato-oblongis nitidis, pedunculis terminalibus dichotomis, segmentis calycinis brac- 

 teisque erectis subulatis, antheris aristatis. — S. divergens. Graham in Ed. New Phil. Journ.

We have restored the old specific name of divaricatus, Loureiro's description leaving no doubt about this 

 being the plant he had in view. We agree with Dr. Graham in thinking it a very distinct species from S. 

 dichotomus, a plant with which Nerium scandens, Lour. Cochin, v. 1. p. 143, and N. caudatum, Roxb. Fl. 

 Ind. v. 2. p. 9. appear identical. In the native specimens the peduncles rarely bear more than two or three 

 nowers. <S. divaricatus of Wallich is probably a different species. 



1. Tabernsemontana bovina. Lour. Cochin, v. 1. p. 145 ? 



The leaves are of a thinner texture than in T. persicaritefolia, Jacq., to which the only specimen in the 

 Collection seems allied: the peduncles have only about three flowers. 



2. T. mollis ; ramulis glabris apice tantum foliiferis, foliis oblongo-ovatis basi apice vix 

 acutis (junioribus) utrinque molliter pubescentibus, corymbis sessilibus terminalibus pauci- 

 floris calycibusque pubescentibus, bracteis minutis oblongis. 



This is a true Tabernmmontana, but certainly not among those described by Loureiro, nor, indeed, have 

 we been able to find it under any other genus in his work. We possess T. coronaria, Willd. from Mr. Millett.

Loureiro's plant was observed only on the eastern coast of Africa, and he states that he had never seen it 

 in India or China; his description, however, seems to accord.
