Berberis umbellata. Wallich {alias B. angulosa and gracilis of Gardens). A 

 handsome hardy evergreen bush, with pale yellow flowers, appearing in May. Native of 

 the Himalayan mountains. (Fig. 179.) 



Dr. "Wallich's collectors appear to have first discovered this plant in Kamaon and Gossain Than. For its intro- 

 duction to our gardens we are indebted to the East India Company. It is a hardy bush, about 4 feet high, with 

 a spreading manner of growth, pale brown, angular branches, slender three-parted spines, and very narrow, bluish-green 

 leaves, strikingly glaucous beneath ; on an 

 average they are If inch long by f wide ; 

 sometimes they are perfectly entire, in which 

 state they are represented in the Botanical 

 Register; but they are more commonly fur- 

 nished with a strong, marginal, spiny tooth 

 or two, and sometimes with many. (Can this 

 state be the B. ceratophylla of G. Don ?) 

 The flowers are pale yellow, in drooping, 

 narrow racemes, and are succeeded by an 

 abundance of oblong, purplish fruits. The 

 species is very pretty, in consequence of its 

 graceful manner of growth. It is best suited 

 for growing among rough places, such as heaps 

 of rockwork, where its spreading way of 

 branching can best be seen. It is not, how- 

 ever, a good evergreen, the leaves being too 

 thin and pallid. — Journ. of Mort. Soc, vol. v. 



Populus Bolleana. The advent 

 of a handsome tree, hardy iu our 

 climate, is always an event worth 

 notice. This Poplar has been intro- 

 duced by Messrs. Paul and Son, of 

 Cheshunt, who obtained it, we 

 understand, from the Continent, 

 where ifc has been in existence some 

 years. It is a native of Turkestan. 

 In habit it is somewhat erect ; it 

 resembles the well-known white Poplar, P. alba, but is sufficiently distinct from that 

 favourite kind to deserve a place of its own. The merits of these quick-growing trees
