and furnished with five very short teeth: the stamens and pis- 
tillum are all alike in structure, and I perceive no difference in 
the fruit or seed. Chanesthes, therefore, as a genus, must verge 
into that of Jochroma, a name that ill accords with a scarlet 
corolla, but one that must remain on the score of priority. I 
suggest, however, the propriety of dividing the genus mto two 
sections, one Jochroma proper, with a purple or greenish corolla, 
the other Chenesthes, with red and orange flowers. To both these 
sections [ will here add several new species, proposing, hereafter, 
to illustrate by appropriate figures, the structure of each section 
respectively. The three plants first alluded to, I propose to sepa- 
rate from Jochroma, under the name of Cleochroma, for the reasons 
stated under that head (p. 147.) Dr. Walpers (Repert. vol vi. 
p- 629) refers Jochroma to the tribe Cestrinez, and in a note 
(2bid, 620) says it hardly differs, as a genus, from Cestrum. This 
statement I cannot in any degree confirm ; on the contrary, after 
a careful analysis, on which the following generic character is 
founded, it will be seen that Jochroma most unquestionably 
belongs to the tribe Solanea.
