The habitat of this plant is wet woods, copses, thickets, and hedges. The habit is the tree or shrub habit. The branches are square when young, slender. The buds are scaly. The leaves are delicate, smooth above, downy below, protected by the lower leaves in bud, which are leathery and folded up in bud, so that they are lobed, with linear glandular stipules at the base. The leaf-stalks bear honey-secreting hollows, attractive to wasps, which prevent the leaves being eaten by larvae. The plant has a peculiar odour in the evening. The leaves are 3-5 lobed, with a long narrow point, the lobes toothed, unequal. The flowers are white in a large rounded cyme with linear bracts, the inner small, fertile, the outer larger neuter, forming a ray. The corolla is wheel-shaped, i.e. the outer flowers, inner bell-shaped, creamy white. The berries are scarlet, rarely (Leicestershire, Derbyshire) orange. The seeds are keeled, flattened. The plant is 6-8 ft. in height, flowering in June and July, and is a deciduous tree or shrub.
The habitat of the plant is woods, copses, borders of woods, hedges in woods, lanes, and in open fields. The habit is climbing or twining, The upper leaves are oblong, united below round the stem, forming a cup in which water collects, serving to prevent insects from climbing up. They are bluish-green below, the lower are stalked, smooth both sides, and distinct, broadly egg-shaped, oblong. The bracts are leafy, large, connected; the flower-heads terminal, stalkless, with a gaping corolla, the tube long. The flowers are white or purple, whorled. The calyx-limb is short, and persists. The style is smooth. The berries are round and scarlet. The pericarp and placenta are fleshy. The plant is a climber, flowering in May and June, and is a deciduous shrub.
The habitat of the plant is copses. The habit is climbing. The plant is downy. The stem is erect, or nearly so. The leaves are stalked, egg-shaped or inversely so, downy. The flowers are axillary, in pairs, short, pale yellow, on 2 flower-stalks, which are downy, as long as the flowers, shorter than the leaves. The limb of the calyx falls at length. There are 2 linear, downy bracts, and minute bracteoles. The ovaries are connected at the base. The anther-stalks are downy. The berries are small, scarlet or crimson. The plant is a climber, flowering in May and June, and is a deciduous shrub.
The habitat of this plant is fir forests and plantations, and heathy woods. The habit is trailing or creeping. The plant is without hairs, except the inflorescence, which is glandular. The stems are slender, threadlike. The leaves are opposite, in distant pairs, broadly egg-shaped, blunt, scalloped, stalked, dark-green above, paler below, leathery. The flowers are pink, sweet-scented, on erect, threadlike, 2-flowered flower-stalks, with 2 bracts above, and are drooping, purple within. The flower-stalks arise from short lateral branches, with 2-4 leaves. The fruit, which is rare, is small, black when ripe. The plant is a trailer, 3-8 in. long, flowering in July, and is an evergreen shrub.
