of long duration, it should never be placed where it is intended to act as a 

 screen. Like all objects the chief beauty of which consists in their singularity, 

 it produces the most striking effect when standing alone on a lawn. If trained 

 to a single stem, either of the forms of this species may be made an interest- 

 ing small tree, but not one of many years' durability. Price, in the London 

 nurseries, 1*. a plant, and seeds 1*. an ounce ; at Bollwyller, 50 cents a plant ;

Sprc. Char., #r. Leaf of 8 10 pairs of leaflets, and the odd one, that are 

 lanceolate-oblong, serrate, pubescent beneath. Petiole and branches

 Flowers green, in upright racemes. Probably a variety of R. glabra. (Ibid.) 

 The plant of R. viridiflora in the garden of the London Horticultural 

 Society was, in 1834, 10ft. high, after having been 10 years planted.

 (Dec. Prod., ii. p. 67.) A native of North America. Fruit covered with 

 silky hairs, red. De Candolle has distinguished three forms of this spe- 

 cies ; namely : 



st R. g. 1 hermaphrod\ta, with hermaphrodite sexes, and greenish flowers ; 



the R. glabra Wttld. Spec., i. p. 1478., and figured in Dill. Elth., t. 243. 



a R. g. 2 dioica, with dioecious sexes, and greenish flowers, figured in 



Lam. Ill.,t. 207. f. 1. 



a R. g. ? 3 coccinea, the R. carolinianum of Mill. Diet., and the R. 

 elegans of Ait., Loddiges's Catalogue, and of nurseries generally, 

 figured in Dend. Brit., t. 16., has dioecious sexes, and red flowers. 

 It is distinguished by a more upright habit of growth, and smoother 

 branches and leaves, than R. glabra. The leaves are glaucous 

 underneath ; and the fruit is of a rich velvety crimson. 

 Description, fyc. The general appearance of the species 

 is similar to that of R. typhina ; but the plant is smaller, 

 the branches more spreading and smooth, and the leaf- 

 lets wider, less serrated, and of a deeper green. There 

 are many varieties of R. typhina in North America; 

 and, to us, it appears highly probable that R. glabra is 

 only one of these. According to Kalm, the species or 

 variety under notice is exceedingly common in woods 

 throughout great part of North America, both in culti- 

 vated and uncultivated districts. In woods, it is found 

 on the margins of open glades; and, in cultivated parts 

 of the country, it less common in low meadows than 

 in corn fields. " It is like a weed in some parts of the 

 country ; and, if a field be left a few years uncultivated, 

 this shrub overruns it, from berries which are brought 

 by birds; and, when the ground comes again into til- 

 lage, the roots stop the plough very much. The fruit 

 remains on the shrub during winter ; but the leaves drop 

 very early in autumn. It seldom grows above 9 ft. high. The wood burns 

 well, without much crackling. On cutting the stem, a yellow juice comes 

 out between the bark and the wood ; one or two of the outer circles of the 

 wood are white, bnt the innermost are of a yellowish green ; it contains a 

 pith frequently half an inch in diameter, or more, of a brown colour, and so 

 loose, that it is easily pushed out by a stick. The branches, boiled with the
