1. P. Cantonensis. (Tab. XLIII.) 
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 Phit. 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 M’ith 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. FI. 
Ind. V. 2. p. 9. appear identical. In the native specimens the peduncles. rarely bear more than two or three 
fiowers. (S', divaricatus of Wallich is probably a different species. 
1. Tabernsemontana Lour. Cochin, v. 1. p. 145.^ 
The leaves are of a thinner texture than in T. persicariafolia, Jacq., to w’hich the only specimen in the 
Collection seems allied: the peduncles have only about three flowers. 
2. T. mottis; 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 Tabernamontana, 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.
