CLASS V. ORDM I.] CONVOLVULUS. 263 



calyx, leafy, quite smooth. Calyx of five orate segments, about half 

 as long as the bractea. Corolla bell-shaped, folded with five plaits, 

 and indistinctly lobed. Stamens arising from the base of the corolla, 

 equal in length, not half as long as the corolla. The filaments dilated 

 downwards, downy. Anthers oblong, arrow-shaped. Style smooth, 

 longer than the stamens, slender. Stigma of two spreading ovate 

 downy lobes. Capsules of one or four imperfectly formed cells. Seeds 

 ovate, few. The capsules are seldom perfected ; the plant increasing 

 by its underground, stems. 



Habitat. Woods, hedges, and thickets, especially in a moist soil j 

 frequent. 



Perennial ; flowering from June to August. 



This beautiful species of Convolvulus is much larger than the last, 

 and highly ornamental to our rural lanes and sequestered dells, throw- 

 ing ils slender arms around perhaps the fragrant woodbine, and 

 mingling with its sweets its gay and more conspicuous attire, adorning 

 the sylvan bower in rich festoons of varied hues; or climbing some 

 tree hard by, it hangs pendent from its outstretched boughs its length- 

 ened folds of living drapery. It is readily distinguished from C. 

 arvensis, by its large bracteas beneath the calyx. The flowers are 

 mostly much larger, and the stigmas two obtusely ovate lobes. 



3. C. soldanel'la. Linn. (Fig. 345). Sea-side Bindweed. Stem 

 prostrate; leaves kidney-shaped, fleshy; peduncles single flowered, 

 four sided, somewhat winged ; bracteas large, ovate, close beneath the 

 calyx.

Root with numerous long creeping branched underground stems. 

 The whole plant smooth and succulent. Stem branched, spreading on 

 the surface of the sands, angular, from six to twelve inches long, or 

 longer. Leaves alternate, sometimes opposite, roundish, heart or 

 kidney-shaped, pointed, lobed, and obtusely toothed, with a mid-rib 

 and several radiating veins, on a rather long broadish channelled 

 footstalk. Flowers solitary from the axis of the leaves, large, very 

 handsome, a delicate rose colour, with a palish yellow ray, nearly two 

 inches across the mouth, and almost as long, on a long square stalk, 

 dilated upwards, the angles more or less distinctly winged, and some- 

 what pinkish, having two large ovate leafy bractea immediately be- 

 neath the calyx, with a mid-rib, and finely reticulated with veins. 

 Calyx of five ovate segments, longer than the bractea, with a minute 

 point and pinkish raid-rib. Corolla bell-shaped, with five broad plaits, 

 and five somewhat pointed lobes. Stamens arising from the base of the 

 corolla, and about half as long, nearly equal ; the filaments dilated
