Robinia 1509 



It is probably a hybrid between R. hispida and R. Pseudacacia, resembling the latter 

 in the slightly pubescent and usually non-glandular ^ branchlets, and in the small size of 

 the leaflets, which are seven to eleven in number, ^ to i|- in. long, glabrous, lanceolate, 

 and tipped with a conspicuous mucro. The flowers are similar to those of R. hispida, 

 but smaller ; and are pink in colour, few (about five to eight) in the raceme, — with the 

 peduncle, axis, pedicels, and calyx more or less covered with stalked glands, all the 

 calyx-lobes being subulately pointed. Fruit reddish, i|- to 2 in. long, densely 

 covered with glandular hairs ; seeds three to four. Stipular spines are present on 

 the branchlets, but are feebly developed. 



This was introduced into commerce about 1901, and shrubs planted at Kew in 

 1903 have flowered and produced fruit.^ It is not so rank in growth as R. hispida, 

 and is less liable on this account to be injured by the wind. According to Mr. Bean, 

 it can be readily propagated by grafting on the roots of R. Pseudacacia. 



R. hispida, commonly known as the rose acacia, occurs in the mountains of 

 Virginia, Kentucky, Tennessee, North and South Carolina, Alabama and Georgia. 



It was introduced^ into cultivation in England by Sir John Colliton at 

 Exmouth, in 1741. It is a handsome shrub with beautiful flowers, produced in June 

 and July. It is usually grafted on the common Robinia ; but Nicholson says that 

 as it is readily propagated by root-cuttings, this mode of reproduction is preferable.

* The branchlets bear occasionally one or two stalked glands.

 Horticultural Society on June 7, 1 9 10.
