PETREA VOLUBILIS. 
Class, Order, 
DIDYNAMIA ANGIOSPERMIA. 
This genus was named in honour of 
Robert James Lord Petre, who died in 1742, 
atthe early age of thirty-two. This nobleman 
was a munificent encourager of botany, and 
had himself the finest collection of plants in 
this kingdom. 
It is a very beautiful climber; a native 
of Vera-cruz, Caraccas, and Martinique. 
With us it grows to ten or twelve feet in 
height, with proper support, and produces 
its elegant pendulous blossoms in succession 
during the greater part of the year. 
It must be kept always in the stove, as it 
loves heat, and may be increased by cut- 
tings: the soil should be rich loam and 
peat.
