 It is perhaps a species of Ccesalpinia. 

 Climbing Genista; Shrub cl. 



is usually cultivated for ornament, 

 colour, and will polish very well; it approaches near to green 

 ebony, and is called by the French ebony of the Alps, and is there 

 used for many kinds of furniture ; but in England there are tew 

 of the trees which have been suffered to stand long enough to 

 arrive at any considerable size. Haller observes that Laburntm 

 is very bitter, that the seeds are violently purgative and emetic 

 He also remarks that the Latin name Laburnum was eviuenUy 

 formed from the Alpine name UAuhours. In German it ^ 

 called Bohnenbaumy and in French Cytise des Alpes, Juboun 



Cult. All the species of this genus are very elegant when in and Faux Ebenier. The seed of Laburnum is frequently sowniB 



flower. The hardy species are well fitted for the front of shrub- plantations infested with hares and rabbits, who will touch no 



other tree as long as a twig of Laburnum remains. llio"o 

 eaten to the ground every season, it rises again in the spring) 

 thus affording a constant supply for these animals, so as to sa 



cuttings of them root readily if planted in a pot of sand, with a the other trees till of a size to resist their attacks. The tree 



bell-glass placed over them, but the glasses must be taken off* 



and wiped occasionally, otherwise the cuttings are apt to damp offl 



beries, as they are generally of low growth ; they are usually in- 

 creased by seeds or layers. The greenhouse and frame kinds 

 thrive well in a mixture of loam, peat, and sand, and young
