described by Mr. Don, as:a native of Nepal; and now 
a third species, the subject of the present plate, has been 
detected: in: the’ Organ mountains, near Rio Janeiro, by 
Wituiiam Harrison, Esq., and by him introduced to the col- 
lection of his sister, Mrs: Arnorp Harrison, of Aigburgh, 
near Liverpool, where it flowered in November, 1827, and 
by whom it was kindly communicated to me. The habit 
of the plant is, indeed, considerably different from that of 
the species already figured in this work, but in the struc- 
ture of the flower, and in the essential. generic characters, 
they are the same. —
