taking root at their joints. According to Woodward, the flowering- 

 stem is upright in the spring, but in autumn the flowers are borne 

 on the shoots of the year, which are trailing: the leaves opposite, on 

 footstalks about one-fourth the length of the leaves, which are quite 

 entire, evergreen, shining, somewhat like those of Privet, not having 

 the fringed edge observable in the second sort: the flowers axillary, 

 alternate, solitary, void of scent, on nearly upright peduncles, almost 

 twice the length of the leaves, round, smooth, and shining, pale blue. 

 It is a native of Germany. 



It varies in the colour of the flowers; with pale blue, with purple 

 and white, and with double flowers; and the foliage is sometimes 

 variegated either with white of yellow stripes. 



The second species is larger in all its parts than the preceding: 

 the stems erect, finally rooting at the end: the leaves broad-ovate, 

 three inches long, and two broad, of a thick consistence, finely 

 fringed with short rigid hairs at the edge, on thick footstalks: the 

 flowers solitary, alternate, on peduncles half the length of the leaves, 

 of a purple-blueish colour. It is a native of France, Spain, &c 

 flowering in May. 



The third has an upright branching stem, three or four feet 

 high, when young, succulent, jointed, purple; but as the plant ad- 

 vances the lower parts become woody: the branches have the joints 

 very close, are covered with a smooth purple bark, and have oblong, 

 ovate, entire leaves, two inches and a half Jong, and an inch and 

 half broad, smooth and succulent, setting pretty close to the 

 branches: the flowers axillary, solitary, on very short peduncles: 

 tube long and slender: brim spreading open, flat, divided into five 

 broad obtuse segments, which are reflexed at their points: the upper 

 surface of the petal is of a bright crimson or peach colour, and their 

 under side pale flesh-colour: there is a succession of flowers, from 

 February to the end of October. It is a native of Madagascar, 

 China, &c.
