 It is perhaps a species of Ccesalpinia. 



Climbing Genista, Shrub cl, 



Cult. All the species of this genus are very elegant when in 

 flower. The hardy species are well fitted for the front of shrub- 

 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 

 cuttings of them root readily if planted in a pot of sand, with a 

 bell-glass placed over them, but the glasses must be taken oft' 

 and wiped occasionally, otherwise the cuttings are apt to damp off.

 is usually cultivated for ornament. The wood is hard, of a fine 

 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 few 

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

 arrive at any considerable size. Haller observes that Laburnum 

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

 He also remarks that the Latin name Laburnum was evidently 

 formed from the Alpine name L'AubauTt. In German it is 

 called Bohncnbaum, and in French Cijtise des Alpes, Aubours, 

 and Faux Ebcnier. The seed of Laburnum is frequently sown in 

 plantaiions infested with hares and rabbits, who will touch no 

 other tree as long as a twig of Laburnum remains. Though 

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

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

 the other trees till of a size to resist their attacks. The tree 

 grows best in light loam, or sandy soil.

 or Ci/tisus a'pi.ius, is a native of Switzerland and Scotland ; it is 

 cultivated chiefly for ornament, but affords also a valuable tim- 

 ber ; for this purpose the C. alplnus is decidedly preferable to 

 the common kind, as being mote of a tree. The wood of both
