SENT from Clapham, Bedfordshire, by the Rev. Dr. Abbot.
It is a native of dry gravelly and chalky soils among bushes,
flowering in June and July, and is in no respect worthy of
attention as an object of culture.
The root we believe to be perennial, and it branches at the
top so as to bear several stems, each of which is erect, straight,
12 or 18 inches high, but little branched, round and hairy.
Leaves remote; the uppermost only opposite. Stipulas large,
combined, clasping the stem, sharp-pointed, downy, ribbed
with simple nerves. Lower foot-stalks long, bearing broad,
inversely heart-shaped, entire, hairy, leaflets; the upper leaflets
are longer and narrower. Head of flowers terminal, solitary,
stalked, erect, hemisphserical, dense. Calyx slender, furrowed,
\ hairy, with taper teeth, of which the lowermost is
about thrice as long as the rest. Petals joined at the base,
narrow, of a peculiar pale buff or faint sulphur-colour, by
which the species is known at once from all others of British
growth.
