F r e q u e n t on rather moist and shady banks near rivulets,
bearing capsules in April or May, sometimes much later in
the summer. We have gathered it at the Hermitage near
Edinburgh in August.;
This has the habit of P. subrotundum and nanum, t. 1624,
1625, but the stem is rather taller, though still always perfectly
simple. Leaves more rigid and somewhat broader, strongly
serrated at the edge, and even towards the top of the keel,
concerning which last the description in FI. Brit, requires
some correction. Fruitstalk an inch or more in height, red,
almost straight. Capsule scarcely drooping, but a little oblique,
cylindrical, its mouth slightly dilated. Fringe of 32 teeth.
Lid convex, with a small curved beak.
We have represented at A, A, a male flower, with the
stamens, accompanied by some abortive filaments, all more
or less magnified.
