ARBORETUM ET FRUTICETUM BRITANNICUM. 



neated at the base, and obtuse at the apex, smooth. Racemes terminal, stalked, 

 pyramidal, straight; pedicels 

 hoary and villous. Calyxes 

 campanulate, 3-lobed ; lobes 

 tomentosely ciliated.Corolla 

 glabrous, but the carina is 

 clothed with silky villi. Le- 

 gume glabrous, mucronate 

 by the style. (Don's Mill.) 

 An erect woody shrub, re- 

 sembling a laburnum. Dal- 

 matia, in woods on moun- 

 tains. Height 2 ft. to 3 ft. ; 

 6 ft. to 8 ft. in gardens. In- 

 troduced in 1837. Flowers 

 yellow, fragrant ; June and 

 July. Legumes brown ; ripe 

 in October. 



The racemes are erect, and 

 do not droop even when in 

 fruit. The seeds are still more 

 poisonous than those of the 

 common laburnum, and the 

 scent of the flowers causes 

 headach. The milk of the 

 goats which feed upon the flowers, Baron Welden observes, produces the same 

 effect, only more severely, upon those who drink it.

Spec. Char., $c. Branches round, twiggy. Leaves 

 stalked, and clothed with closely pressed down 

 beneath, as well as the branches, calyxes, and 

 pods; leaflets elliptic. Racemes elongated, ter- 

 minal, erect. Calyxes without bracteas. (Dec. 

 Prod.) A handsome deciduous shrub. Piedmont, 

 Vallais, and Bohemia. On hills and along way- 

 sides. Height 3 ft. to 6ft. Introduced in 1730. 

 Flowers yellow ; June and July. Legume black ;

It ripens seed in abundance ; and it may also be 

 propagated by grafting on C. .Laburnum, thus form- 

 ing a handsome standard.
