We suspect this very curious plant to be a mule
between plants of two different sections, perhaps P.
graveolens and P. cortuscefolium, or echinatum. We
should have thought it a species, if its stamens had
not been always imperfect. We have never been able
to fertilize it, though set with the pollen of several
kinds; another proof of its hybrid origin. It is a plant
well worth cultivating, being an abundant flowerer;
and having no inclination to seed, the flowers last in
perfection for a considerable time; so that the whole
plant is often covered with flowers. It was thus
when our drawing was taken at the nursery of Messrs.
Colvill last summer. It is a very hardy free-growing
plant, and thrives well in a mixture of sandy loam
and peat, or any light vegetable mould ; and cuttings
root readily if planted under hand-glasses, or in pots
placed in a shady situation.
Although it has the habit of P. graveolens, excepting
the swollen joints, the flowers have the essential
characters of our section Monospatalla, and it must
therefore rank near P. bicolor in systematical arrangement.
