two. The fruit produced by D. dependens consists of small, dry, blackish 

 purple berries. The species appear highly desirable to all who have a con- 

 servative wall, if it were only to excite an interest in plants in the minds of 

 children, by exhibiting to them the curious action of the leaves.

 Spec. Char., Sfc. Leaves mostly, especially upon the flower. 



bearing branches, obovate, and very obtuse, or even emar- 



ginate, with scarcely any denticulations. Racemes scarcely 



exceeding the leaves in length. Stamens mostly 10. Flowers 



smaller than those of D ovata. {Lindley, in Bot. Reg., 



t. 1573.) A tree, a native of Chili, where it is called 



Huinghan. {Dec. Prod., ii. 'p. 74.) Introduced in 1790. 



There is an old plant of it in the Botanic Garden at Kew, 



against a wall with a west aspect, which has attained a 



considerable size, with very little protection. There is 



also a tree in the Chelsea Botanic Garden, which is 12 ft. 



high, with a trunk 7 in. in circumference, after having 



been 5 years planted. The plant in the London Horticul- 

 tural Society's Garden has passed seven winters against a 



wall with a southern exposure. The winter of 183j-6 hav- 

 ing been unusually severe, has withered the leaves and the 



smaller shoots of this and of some other species of Duvaua 



in this garden ; but, on examining the trees, April 20. 1836, 



we find the stronger shoots, and the trunk and branches, uninjured, and buds and leaves rapidly 



developing themselves.

Spec. Char., S(C. Leaves ovate, toothed, in most acute at the tip, in some obtuse. Racemes a little 

 longer than the leaves. Stamens mostly 8. {Lindley, in Bot. Reg., t. 1568.) Nearly related to D. 

 dependens ; " but the plants are so different when growing side by side, that we cannot think it 

 right to combine them." {Lindley.) About 6 ft. high. Branches spinescent. Introduced about 

 1825 or 1826. The plant in the Horticultural Society's Garden was planted in 1831. To us it 

 appears only a variety of the preceding species.

Spec. Char., §c. Leaves oblong, acute, coarsely toothed, so 

 waved as to seem in some measure plicate. Racemes 

 dense, the length of the leaves. Stamens 8. {Lindley 

 in Bot. Reg., t. 1580.) " Whatever maybe thought" of 

 the distinctness, as species, " of D. ovata and D. depen- 

 dens, there can be no doubt that this is a totally distinct 

 species ; for not only are the leaves, in their outline, sur- 

 face, and colour, and the whole plant in its habit, very 

 different, but we find it maintain all its peculiarities un- 

 changed when raised from seeds." {Id.) This species is 

 very common in Chili, and is called there Huing han, 

 as well as D. dependens. It was introduced into Britain 

 in 1829, or before. The plant in the Horticultural So- 

 ciety's Garden was placed against the wall where it now 

 stands in 1829. This species, judging from the above-men- 

 tioned plant, as examined by us April 20th, 1836, appears 

 to be somewhat more tender than D. dependens ; but this 

 may be owing to its larger leaves presenting a greater sur- 

 face to the action of the weather. We have already more 

 than once remarked, that, when the majority of a species of 

 a genus are hardy, the probability is that those species of 

 that genus which are found to be rather tender may, uy 

 cultivation through several generations, or even peihaps 

 by extension, become hardy. The first, Sir Joseph Banks 

 alleges, has been the case with Zizania aquatica ; and the second, according to Dr. Walker, with 

 Passiflbra cteriilea.
