Distinct. Char., c'j-c. The whole plant, including the young wood, is covered 

 with pubescence. The flowers are large, showy, continuing a long time 

 expanding, and numerous, though they are but sparingly succeeded by fruit. 

 When the plant is raised from seed, it is remarkable for its thick, fleshy, 

 carrot-like roots, which, in free soil, penetrate perpendicularly to the depth 

 of 8 ft. or 10 ft., as has been found to be the case in the Hammersmith 

 Nursery. This sort was introduced from North America (where it is found 

 principally in the western territory of Georgia), in 1812, by Mr. Lyon. 

 Unless when grafted on yE. Hippocastanum, it is seldom seen above 4 ft. 

 or .5 ft. in height; but it is a very free flowerer, and, considered as a shrub, one 

 of the most ornamental in May that can be planted. The plant in the garden 

 of the London Hort. Soc. was, in 18.34, 4 ft. high, after having been 3 years 

 planted. There are varieties of it in the nurseries under different names ; 

 one of these, raised by Messrs. Rivers at Sawbridgeworth, bears the name 

 of P. carnea pubescens. There is a handsome specimen of this bush in the 

 Hanmiersmith Nursery ; it is about 5 ft. high, and 6 ft. or 8 ft. in diameter, 

 and is profusely covered with bloom every year. A large tree of the com- 

 mon horsechestnut, covered with grafts of this species, as recommended in 

 the case of P. hurailis, would form a noble object. Scions taken from flower- 

 ing trees, and grafted on P. humilis, would form beautiful miniature trees 

 for pots. Scions from flowering trees, grafted on stocks of this species, 

 flower the second year, and form the most beautiful flowering shrubs for 

 small gardens that can well be recommended. The same may truly be said 

 of P. humilis, and P. macrostachya, and yet none of these species are 

 ever to be met with in the suburban gardens of the metropolis. Plants, 

 in the Loudon nurseries, cost 2s. Gd. each.

Dustinct. Char., Sfc. Leaves clothed beneath with velvety pubescence, petioles 

 smooth; flowers variegated with yellow, white, and purple. The tree in 

 the London Horticultural Society's (iarden wa.s, in 18.34, 6 ft. high, after 

 having been 5 years planted. The leaves and flowers bear some resem- 

 blance to those of P. di.scolor ; but the flowers of P. hybrida are more 

 sparingly produced. This sort is not in general cultivation ; though, like 

 every other kind of Pavia and ^"sculus, it well deserves to be so.

Disthict. Char., Sfc. Leaves with rufous down on the veins on the upper 

 side, .smooth beneath; rather plicate. Flowers pale yellow, veined with 

 red. This is a tree resembling the preceding sort, and, like it, is apparently 

 a hybrid between P. rubra and P. discolor. It was purchased by the 

 London Horticultural Society from M. Catros of Bordeaux, under the name 

 of A'l. ohiocnsis. In the Botanical licgisfcr, it is said to be most nearly 

 related to .E. (Pavw) flava, but to differ from it in the flowers appearing 10 

 days earlier, and in the leaflets being more glabrous, with rufous (lown on 

 the veins on the upper side, and with hairs in the axils of the veins on the 

 under surface. There is a tree of this sort in the garden of the London 

 Horticultural Society, which, in 1834, was 12 ft. high, after having been 

 8 years planted ; but it has scarcely yet found its way into the nurseries.
