ROBINIA

informs me in a letter that it was "discovered in our nursery apparently 

 growing spontaneously. We thought at first it was a cross between R. hispida 

 and R. Pseudacacia, but now we think it is a true species that has crept into 

 the collections from the southern Allegheny Mountains." It was introduced 

 to Kew in 1903, and is certainly one of the most beautiful shrubs added to 

 gardens in recent years. The flowers appear in great profusion in June, 

 and they are followed by handsome red pods. Its affinity with R. hispida, 

 especially the smooth-branched form, is apparent, but it is abundantly distinct. 

 Judging by its behaviour at Kew it can be made into a small tree, but it is 

 very brittle. Increase is easily effected by grafting on roots of R. Pseud- 

 acacia in spring. Should R. Boyntonii, As/ie, prove to be the same, that name, 

 as the older one, will have to be adopted, but I have seen no material.

Native of Colorado, New Mexico, Arizona, and S. Utah, in places at 

 7000 ft. above sea-level. First discovered by Dr Thurber in 1851; introduced 

 to Kew in 1887, where the original tree is now nearly 3Oift. high, with a trunk
