well-known name. It succeeds well almost anywhere, and, 

 though usually seen as a wall plant, is perfectly hardy, 

 and forms a neat shrub for the open border. There is a 

 form in which the leaves are variegated, and known under 

 the name of K. japonica variegata. 



Koelreuteria (Sapindaceae). 



KCELREUTERIA PANicuLATA. Northern China, 1763. 

 Whether for its foliage or flowers, this small-growing 

 tree is worthy of a place. Though of rather irregular 

 growth, the beautiful foliage and large panicles of yellowish 

 flowers, which stand well above the leaves, make the shrub

 it grows and flowers freely. 



Laburnum (Leguminosae), 



LABURNUM ADAMI (syn Cytisus Adami). A graft hybrid 

 form between the common Laburnum and Cytisus pur- 

 pureus, the result being flowers of the Laburnum, the true 

 Cytisus purpureus, and the graft hybrid between the two. 

 It was raised by Jean Louis Adam in 1825. It is a 

 curious and distinct tree, worthy of culture if only for the 

 production of three distinct kinds of flowers on the same 

 plant. 



L. ALPINUM (syn Cytisus alpinus). Scotch Laburnum. 

 Europe, 1596. This very closely resembles the common 

 Laburnum, but it is of larger growth, and flowers later in 

 the season. The flowers, too, though in longer racemes, 

 are usually less plentifully produced and with a shorter 

 fruit pod. It grows 30 feet high. There is a weeping 

 form, L. alpinum pendulum, and another with fragrant 

 flowers, named L. alpinum fragrans, as also a third,
