with short stiff hairs, more than five times longer than 
the calyx. Petals 5, the two uppermost roundly ovate, 
of a yellowish green, inclining to brown, unequally 
marked with black in the centre, lower petals oblong, 
obtuse, of the same colour, but more marked, the spot 
generally 2 or 3-forked at the apex. Filaments 10, 
united at the base, 7 bearing anthers ; one of these is a 
flat spatulate one, as in all the plants of this section. 
Germen and aristae villous. Style short, green, and 
smooth. Stigmas 5, spreading. 
This plant is without doubt as distinct a species as 
any of the tribe ; it differs more from P. triste than that 
does from V.Jiavum; it is of much stronger growth, 
producing a great many umbels of flowers on its glau- 
cous stem ; the leaves are also much less hairy than in 
P. triste, and the segments of quite a different shape ; 
the flowers are very sweet-scented in the evening as in 
several other species of this section, but they are with- 
out scent during the day. 
Our drawing was taken from a strong plant in the 
collection of Robert H. Jerikinson, Esq, in August last. 
It thrives best in an equal mixture of turfy loam, peat, 
and sand ; the readiest way of propagating it is by the 
little tubers of the root, planted in the same kind of 
soil, with their tops just above the surface of the earth ; 
these may be set on a shelf in the greenhouse, but will 
require very little water till they begin to grow, when 
they may be watered regularly.
