The habitat of this species is thickets. The mature thorns are straight, rarely or slightly curved. The stem is tall, prickly, nearly straight. The leaflets are egg-shaped, elliptic, with numerous glands, hairy. The sepals are persistent till the fruit is ripe, glandular, egg-shaped, lance-shaped, sub-erect in fruit, the flower-stalk short, variable in length, with large bracts. The plant is 3-6 ft. high, flowering in June and July, and is a deciduous shrub.
Rosa agrestis, Savi. = R. septum, Thuill. - The habitat of this plant is thickets, chalk downs, etc. The stem is sub-erect, with long, loose branches. The prickles are unequal, hooked, with a few aciculi and glandular hairs. The leaflets are small, narrowed both ends, very glandular below, hairless or hairy on the veins below, doubly-toothed. The flowers are 1-3, pink. The sepals are nearly persistent, closely pinnate. The flower-stalk is naked. The styles are hairy, downy. The early fruit is egg-shaped or nearly rounded, naked. The disk is moderate. The plant is 3-6 ft. high, flowering in June and July, and is a deciduous shrub.
This rose is commonly found in plantations and is an escape from cultivation. The plant is evergreen, shining, the branches are long, prostrate, the leaflets on the flowering branches are only 5. The sepals are shining, glandular on the back. The column of the styles is hairy. The plant is 3-4 ft. high, flowering in June and July, and is an evergreen shrub.
The habitat of this plant is copses and borders of forests, hilly woods. This and other species were formerly considered subspecies of Pyrus Aria (see Volume III, Section V). The habit is the tree habit, as in the latter. The leaves of the flowering shoots are elliptical, with 5-9 lateral veins on each side, less prominent below, egg-shaped, acute or oblong, lobed, the lobes often acute, triangular, deepest near the middle, toothed, with a long narrow point. The under side of the leaves is grey-felted, and floccu-lent with tufts of wool. The white flowers are in a corymb. The fruit is red or darkish-brown. The plant is considered a hybrid between P. Aria and P. torminalis. It is a tall tree, flowering in May and June, and is deciduous.
The habitat of this plant is woods. The plant has the tree habit, and the leaves are oblong, doubly-toothed near the tip, deeply divided nearly to the base below, the lobes oblong, lance-shaped, toothed, the lobes more united toward the extremity of the leaf, which is only deeply doubly-toothed, hence the name intermedia. The under side is white and downy. The white flowers are in a corymb. The anthers are pink, the stamens long-. The fruit is scarlet. The plant is tall, flowering- in May and June, and is a deciduous tree.
Pyrus scandica, E. & H., non Aschers. - This species is only found in two vice-counties. Mr. Druce in his Oxford list unites P. scandica, Aschers, with P. intermedia, Ehrh. The late Rev. A. Ley regards the Arran plant with broader leaves and larger fruit, from the west of England, as distinct from the Arran plant (P. scandica, Syme, Sorbus scandica, Fries) and P. scandica, Aschers. This name is retained in the last 10th edition (1908) of the London Catalogue. The P. scandica, E. & H., Mr. Druce places as a variety of P. intermedia, Ehrh. It differs from the latter as defined by Mr. Druce in the leaves being less narrowed, almost rounded at the base, deeply lobed, with numerous sharp teeth, and 6-8 pairs of leaves. The fruit is large.
