second day to a yellowish green. Filaments 10, straight, 
united at the base, seven bearing anthers ; one of those 
is a spatula-shaped one, with a smaller anther. Style 
short, hairy at the base. Stigmas 5, reflexed. 
This curious plant is a hybrid production, and was 
raised at the nursery of Mr. Colvill, in 1822, from a seed 
of P. gibbosum that had been fertilized by the pollen of 
P. particeps, and it is as near as possible intermediate 
between the two : the flowers, when first expanded, are 
of a light purple colour, but they soon change to a 
yellowish green, and are fragrant in the evening. Se- 
veral other curious mules from plants belonging to this 
section we expect to see flower this season : some be- 
tween P. gibbosum and P. multiradiatum; others be- 
tween the latter and P. ardens we are in hopes of see- 
ing bloom before long ; and also several very curious 
ones from P. sanguineum, some of which are shrubby, 
and others stemless; some with divided leaves, and 
others entire. 
The present plant thrives well, and grows very 
strong in an equal mixture of rich turfy loam, peat, 
and sand. Cuttings of it strike root readily, if planted 
in pots and placed in the greenhouse: it may also be 
increased by the tubers of its roots. Drawn at the 
nursery of Mr. Colvill, in October last.
