the length of the calyx, slightly flattened on each side, and 
thickly clothed with spreading hairs. Petals 5, the 2 upper 
ones slightly retuse, narrowly cuneate, of an orangy scar- 
let, white at the base, and marked from there to the middle 
with a few short branched dark purple lines : lower petals 
about half the width of the upper ones, of rather a lighter 
colour, and white from below the middle Filaments 10, 
united at the base, 7 bearing anthers. Style short, purple, 
thickly clothed with short hairs. Stigmas 5, purple, re- 
flexed. 
A very pretty hybrid plant, raised in 1823 at the Nur- 
sery of Mr. Colvill, from the seed of a mule from Dima- 
eria pinnata, that had been fertilized by the pollen of 
P. ardens ; the leaves and the colour of the flowers are 
very similar to its former parent, but its habit, loose growth, 
and form of the flowers, is more like the latter : it is a very 
free growing sort, and an abundant bloomer, beginning to 
floM^er the latter part of February or the beginning of March, 
and our plant was very fine in flower the beginning of No- 
vember: like its nearest relatives, it succeeds best in a 
light sandy soil, and requires very little water after it has 
done flowering : an equal mixture of light turfy loam, peat, 
and sand, is a very proper soil for it ; and the pots must 
be well drained with potsherds broken small, that the mois- 
ture may pass readily ofi^ : the best method of increasing it 
is by the little tubers of its roots ; the most proper time 
for taking those ofi^, is when the plants are in a dormant 
state, as they can then be kept quite dry till the wound is 
dried up ; they would otherwise be liable to rot: the roots 
must be planted with their tops above the surface of the 
mould, to prevent their rotting ; and as soon as the cut is 
dried up, they may be regularly watered, and they will 
soon make nice young plants, and will flower the first 
Summer.
