The 3 lower teeth of the calyx acuminated. Roots 

 creeping. (Dec. Prod., ii. p. 262.) This kind of 

 robinia is a native of South Carolina and Georgia, 

 near rivers. It usually grows to the height of 

 30 ft. or 40 ft., and was introduced in 1797. The 

 flowers are scentless, and are generally of a pale 

 pink, mixed with white ; though there are varie- 

 ties, or, perhaps, only variations arising from dif- 

 ference of soil, with the flowers of a pale purple 

 or violet colour. The bark, particularly that of 

 the young shoots, which is of a dull red, is 

 covered with a clammy substance, which, when 

 touched, sticks to the fingers. In every other 

 respect, this tree strongly resembles the com- 

 mon R. Pseud-Acacia, of which we believe it to 

 be only a variety ; though so distinct, from the clamminess of its bark, and 

 the colour and want of scent in its flowers, that we have kept it apart. The 

 clammy matter exuded from the bark of the young shoots is said to have 

 been examined by Vauquelin, and found to be a new vegetable substance. 

 In England, we have observed that this clamminess differs much in different 

 trees, and in some is almost wanting. 



Properties and Uses, Sfc. This tree, being of less magnitude and duration 

 than the common locust, arrives sooner at perfection, and, consequently comes 

 sooner into bloom. It also flowers a second time in some seasons, both in 

 its native country and in England. As its flowers are large, and conspicuous 

 from their colour, the tree well deserves a place in every ornamental plant- 

 ation. The wood resembles that of the common locust; but the tree, even 

 when full grown, is seldom found with a trunk above 10 in. or 1ft. in di- 

 ameter. In all other respects but those which have been mentioned, the tree 

 is, and may be, treated like the common locust. 



Statistics. In the neighbourhood of London, there are no very large trees ; those in the Horti- 

 cultural Society's Garden, and in the arboretum of the Messrs. Lodiliges, being only about 30 ft. high. 

 The rate of growth, in different situations and circumstances, is nearly the same as that of R. Pseud- 

 ^cacia, for the first 5 or 6 years. In Surrey, at Bagshot Park, 20 years planted, it is 20 ft. high ; at 

 St. Anne's Hill, SO years planted, it is 33ft. high ; in Sussex, at West Dean, 14 years planted, it is 

 31 ft. high ; in Berkshire, at White Knights, 34 years planted, it is 33 ft. high, the diameter of the 

 trunk 9 in., and of the head 24 ft. ; in Cheshire, at Eaton Hall, 12 years planted, it is 18 ft. high ; 

 in Worcestershire, at Croome, 30 years planted, it is 45 ft. high. In Scotland, at Perth, in the Perth 

 Nursery, 35 years planted, it is 30 ft. high, diameter of the trunk 1 1 in., and of the head 22 ft. In Ire- 

 land, in the Glasnevin Garden, 20 years planted, and 24ft. high, diameter of the trunk 8 in., and of 

 the head 14 ft. 



Commercial Statistics. Plants, in London, are from I*, to 1*. 6d., and 

 American seeds are 1*. a« oz. ; at Bollwyller, plants are from 1 franc to I 

 franc 50 cents each ; at New York, 37£ cents a plant. 



% 3. R. du v bia Fouc. The doubtful Robinia, or False Acacia. 



Identification. Fouc. in Desv. Journ. Bot., 4. p. 204., but not of Poir. ; Dec. Prod., 2. p. 261.; Don's 

 Mill., 2. p. 238. 



Synonymes. R. hy'brida Audib. ; R. ambigua Poir. Suppl., 4. p. 690. ; and, perhaps, R. echinata 

 Mill. Diet., No. 2. ; R. intermedia Soulange-Bodin in Ann. d'Hort. de Paris, 2. p. 43. 



Spec. Char., S(c. Spines very short. Branches, petioles, peduncles, and calyxes furnished with a 

 few glands, rarely clammy. Leaflets ovate. Racemes loose and pendulous. Bracteas concave, 

 caducous, ending each in a long bristle. Flowers sweet-scented, pale rose-coloured. The pods, 

 according to Miller, are thickly beset with short prickles. (Don's Mill., ii. p. 238.) This kind is 

 said to be a hybrid between R. Pseud-^cacia and R. visebsa.
