T h i s species of Pimpinella has, in. Britain at least, been
found only on the limestone rocks below Bristol, and according
to Hudson, near Uphill, Somersetshire. Our specimens
were gathered by Mr. Sowerby in the first-mentioned place,
where the plant was remarked in Ray’s time. It is perennial,
flowering in May and June, and is remarkable among the
umbelliferous tribe for having male flowers on one root and
female on another.
The whole herb is smooth, and of a glaucous hue. Root
tap-shaped, Male plant generally most humble in size, and
less spreading. Stem in both sexes angular, branched,
purplish, leafy. Leaves doubly pinnate, the leaflets nearly linear,
uniform, entire, channelled, Umbels numerous, upright,
simple or compound, Flowers pale flesh-coloured, or pale
buff; the males generally, but not always, without any signs
of a germen; but the females are furnished with stamina,
though imperfect ones. Fruit ovate, furrowed. Stigmas globular,
the invariable generic character, though not sufficiently
expressed in our t. 407 and 408,
