A native of Brazil, whence it was imported by Messrs. 

 Loddiges. The drawing was made in January 1834. 



It is a stove herbaceous plant, growing readily in sandy 

 peat, flowering in its season, and then dying down for the 

 remainder of the year. 



Little is as yet known about the species of this genus ; the 

 following certainly belong to it, besides P. plantaginca.

 that the public should not be as well acquainted as his personal friends.
