ROSACE. 243 
Leaves roundish, oval, oblong-oblanceolate or oblong, white- 
felted or grey flocculent-felted beneath even when old, rounded or 
wedge-shaped at the base, rather obtuse at the apex, more or less 
deeply lobed and serrated at the margins; lobes blunt or sub-acute 
at the apex; veins 6 to 12 on each side. Flowers in compound 
corymbs, with the pedicels and calyx-tube felted. Styles generally 
2, woolly at the base. Fruit sub-globular or ovoid, scarlet when 
ripe.

Leaves roundish- or broadly-oval, ovate, or elliptical, flocculent 
above until after the flowers expand, pure white-felted beneath, 
rounded or abrupt at the base, with numerous small lobes from 
below the middle to the apex, incisions between the lobes deepest 
about one-fourth from the apex; lobes broader than long, pointing 
towards the apex of the leaf, blunt or sub-acute, unequally ser- 
rated; veins 10 to 12 on each side, very prominent beneath.* 
Calyx-segments reflexed in flower, erect in fruit. 
In woods, copses, on chalky banks and limestone rocks. 
Common in the southern halfof England. I have it from Somerset, 
Hants, Wilts, Gloucester, Kent, Surrey, Berks, and Monmouthshire, 
and it probably occurs in the neighbouring counties. One speci- 
men has been sent from Ronald Kirk, Teesdale, by Mr. J. G. 
Baker, but marked as a possible alien. In Scotland it is only to 
be seen in ornamental plantations. 
England, [Scotland], Ireland? Tree. Early Summer. 
A small tree, 10 to 20 feet high, or more rarely merely a large 
bush, with dark brownish bark. Leaves fascicled on the spurs or 
flowering branches, remote on the woolly barren shoots, those of 
the spurs 8 to 6 inches long, flocculent above when young, but at 
length glabrous; beneath pure white, from the abundance of felted 
woolly hairs; leaves on the barren shoots generally narrower than 
the others, more acute and more deeply lobed. Flowers inch 
across, in a much-branched lax corymb, with the pedicels and 
calyces densely woolly. Petals roundish, concave, white. Fruit $ 
* The leaves of the young shoots are exceedingly variable in form ; the descriptions 
are therefore taken from those on the spurs, or short flowering-branches.
