(A moderate sized tree, with smooth grey branches, hoary when young. 
Leaves alternate, crowded about the extremities, stalked, oblong, acute, 
serrated, lobed towards the base, often deeply pinnatifid ; smooth above, 
white (or rather greyish, E.) and finely cottony beneath. Stipulas 
smooth, awl-shaped, attached to the foot-stalks, but deciduous. Flowers 
cymose, cream-coloured. Styles three or four; cells of the fruit soft and 
pliant like those of P. aucuparia, agreeing with them in number. It is 
regularly propagated by seed. Sm. E.) 
Linnaeus considered it as a mule plant, produced between P. Aria and 
P. aucuparia, having the flowers and pistils of the latter, with the foliage 
of the former, the leaves being rather winged at the base, but confluent 
upwards. 
(It would appear that P. hyhrida seems to vary from P. Aria, and to obtain 
the wing-cleft or pinnatifid character by growth in gardens and shrub¬ 
beries; vid. Note, p. 171. Bot. Guide. E.)

(A small tree, conspicuous for the white mealiness or close tomentose ap¬ 
pearance of the under surface of the leaves, likewise investing the flower- 
stalks and calyx. Parallel ribs prominent on both sides of the leaves. 
Flowers white, in large bunches. Styles often three or four. Fruit with 
as many cells, globular, scarlet, dotted, mealy, acid, astringent. Seeds 
two in each cell. E.)

(3. Linn. Sorhus hyhrida . Huds. With, to Ed. 7. Leaves with five 
to seven marginal lobes on each side, slightly pinnatifid, but not so 
more to the gaiety of picturesque scenery, when the glowing vermillion fruit decorates the 
boughs so superbly by its pendent pomes; for botanical language will scarcely allow us to 
say berries, because the seeds are disposed like those of the apple in a fleshy pulp, and 
divided into cells.” Phillips. A variety with yellow-striped leaves is sometimes admitted 
into shrubberies. JEcidiurrt cornutum, Grev. Scot. Crypt. 180: “ Peridia very long, curved, 
pale-brown, bursting from an orange-coloured thickened spot; sporidia sub-globose 
on the inferior surface of the leaves in summer and autumn very frequent: and on both 
sides of the leaves may be occasionally observed Erineum Sorhi , Grev. Scot. Crypt. 23. 
“ Distinct, or somewhat effused, superficial, lax, at first reddish, at length brown ferrugi¬ 
nous ; peridia cylindrical, obtuse, ami somewhat incurved at the summits.” The new 
vegetable acid, named Sorbic Acid, is found most abundantly to pervade the Mountain Ash. 
It differs materially from the Malic acid, but its peculiar properties are not yet thoroughly 
ascertained. New Month. Mag. 1819. The rare insect sJpioit (Attelahus) Sorhi is said to 
haunt this tree. E.)
