of the same province. It is readily distinguished from the former 

 species by its more lax habit, more divaricate branches, and its 

 different inflorescence. Its leaves are from 2 to 3 inches long, 

 1 to 1^ inch broad, on a petiole of 2 lines. The peduncle of the 

 raceme is from 6 to 9 lines long, sometimes even shorter ; its 

 pedicels 4 to 6 lines in length when in flower, and 9 lines in 

 fruit: the flower expanded is about 8 lines in diameter; the 

 calyx when collapsed in fruit is about 5 lines in diameter, and 

 when its segments are expanded, according to Dr. Sendtner, 12 

 to 15 lines across : the berry when ripe is smooth and black, 

 4 lines in diameter, and contains about sixteen seeds. M. Dunal 

 describes two varieties in the ^ Prodromus,' citii ^ 

 rity, plants observed by him in the British Museum ; but I find 

 there only a single specimen with two separate tickets attached 

 to it, bearing his autograph names of Solanum mehnocarpum and 

 Solanum laxum, from which we may infer that his notes have 

 been taken at difierent times, and after a lapse of many years 

 concluded to be those of two separate plants*.
