208 ARISTOLOCHIA ARISTOTELIA 



A. SlPHO, LHeritier. DUTCHMAN'S PIPE. 



(Bot. Mag., t. 534 ; A. macrophylla, Lamarck?) 



A vigorous, deciduous climber, with twining stems, 20 to 30 ft. high ; stems 

 smooth, buds woolly. Leaves kidney-shaped or heart-shaped, pointed or blunt, 

 4 to 10 ins. long, often almost as wide, downy beneath when young, afterwards 

 almost or quite smooth, pale green ; leaf-stalk I to 3 ins. long, smooth, or 

 slightly downy near the blade. Flowers produced in June at the joints, often 

 in pairs, each flower solitary on a flower-stalk 2 to 4 ins. long, clasped by a 

 roundish oval bract on the lower third of its length. Calyx I to i^ ins. long, 

 tubular and inflated, bent like a siphon, and resembling a Dutch pipe ; yellow- 

 green outside ; at the mouth the tube contracts to a small orifice, the three 

 lobes spreading there into a flat, brown-purple border \ to f in. across. 



Native of the eastern United States ; sent to England first in 1783 by John 

 Bartram of Philadelphia. This is the best known of the genus in gardens, and 

 is a handsome-foliaged climber ; its flowers, although not highly coloured, are, 

 like those of the other species, curiously and beautifully constructed. The 

 plant may be used for covering pergolas, arbours, or pillars. Increased by 

 division. The bark and more especially the root have an aromatic odour. 



A. TOMENTOSA, Sims. 

 (Bot. Mag., t. 1369.) 



A vigorous, deciduous climber, 20 to 30 ft. high, with very woolly young 

 stems, leaves, and flowers. Leaves broadly ovate to roundish, heart- shaped 

 at the base, mostly rounded at the apex ; 3 to 8 ins. long, often nearly as wide ; 

 dull pale green, only slightly downy above ; leaf-stalk I to 3 ins. long, woolly. 

 Flowers solitary on a woolly stalk, which is 2 ins. long, gradually thickening 

 upwards. Calyx about ij ins. long, tubular, inflated at the base, bent to 

 resemble a Dutch pipe, f in. wide at the orifice, where it expands into three 

 distinct lobes ; the tubular part of the flower is greenish yellow, the throat dark 

 brown, and the lobes yellowish. Flowers about midsummer. Fruits 2 ins. 

 long, cylindric, angled. 



Native of S.E. United States ; introduced in 1799. Although not so 

 frequently seen in gardens as A. Sipho, this is also a useful climber for similar 

 positions. Its leaves do not run so large, and it is very distinct in its woolly 

 parts, in the more deeply and distinctly three-lobed limb of the calyx, and in 

 the absence of a bract on the flower-stalk. 



ARISTOTELIA. 



A small genus of trees and shrubs, two species of which are in 

 cultivation, one native of Chile, the other of New Zealand. Both are 

 somewhat tender in our average climate, and are only seen at their best 

 in the south-west counties. Given warm enough conditions they will 

 thrive in any soil of moderate quality, and both can be easily propagated 

 by cuttings made of half-ripened wood and put in gentle heat. 



A. MACQUI, LHeritier. 



(Gardeners' Chronicle, 1875, ii., p. 773.) 



An evergreen, spreading shrub, 6 to 10 ft. high, considerably higher in the 

 mildest counties. Leaves opposite and alternate on the same plant, ovate,
