Mr. Brown, in his Prodromus of the Plants of New Hol- 
land, has remarked thatthe genuine species of Exacum are 
sessile, pedunculatum, and perhaps punctatum, with others 
unpublished, natiyes of the, East Indies ;.we have therefore 
thought it advisable to follow the example of ' the Hortus 
Kewensis in retaining our plant in the genus GenrrAna ; from 
which it must, however, undoubtedly be hereafter separated. 
In many respects it approaches to the character of CuIRoNIA, 
but has not the twisted anthers of that genus. 
Native of the Canaries. A biennial, requiring the protec- 
tion of the greenhouse... Flowers in June and July. Propa- 
gated by seeds. Communicated by Mr. Braxs, from the 
collection of James Verz, Esq. of Kensington Gore.
