ing anthers which are always sterile. Germen villous. 
Style pale blush, hairy below, and smooth on the upper 
part. Stigmas 5, pale red, reflexed or revolute. 
We suspect this very curious plant to be a mule 
between plants of two different sections, perhaps P. 
graveolens and P. cortusasfoUum, or echinafum. 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, except- 
ing the swollen joints, the flowers have the essential 
characters of our section Monospatalla, and it must 
therefore rank near P. bicolor in systematical ar- 
rangement.
