in Clova from R . involuta, by its running less at the roots,
as well as by the less crowded prickles. Plants sent by him
to our gardens throw up fewer suckers than our Sussex
R . Doniana, and have longer and more urceolate fruit,
and altogether recede less from R . Sabini. Their flowers
are almost of a pure white ; those of the Sussex plant are
more deeply tinged with pink.
Perhaps Mr. Winch had not seen the true R . involuta
growing, when he proposed, in his Geographical Distribution
o f Plants, to unite R . Sabini and R . Doniana with that
species. To this we cannot assent. Still less can we, with
Seringe, (Decand. Prodr. v. 2. 609,) arrange R. involuta as a
variety of R . spinosissima, (his R. pimpinellifolia,) although
it approaches it by its humble growth and its crowded
prickles. Its fruit, which has not been described, is smaller
than that of R . Doniana, varies from globose to urceolate,
and is dark red when ripe. To supply former deficiencies,
we add a representation of it, from a plant from the Cambridge
garden, at fig. 2; as also of the fruit of R . rubella,
t. 2521, received from Mr. Winch, at fig. 3.—W. B.
