This fine large shrub has been in cultivation in the Arboretum under the 

 name of B. aristata, of which I give a short account below. It was raised 

 in 1895 from seeds collected from no. 67 which is B. heteropoda according 

 to the material preserved in the herbarium. B. notabilis therefore un- 

 doubtedly represents a hybrid of B. heteropoda, and this origin is clearly 

 shown by the characters of the leaves and by the distinctly stipitate 

 ovules. The species which is to be regarded as the second parent I am 

 not yet quite sure of. Some features point to B. aristata to which our 

 plant is similar when flowering but B. aristata has leaves of a thicker texture 

 and coarser serration, its racemes are not as large, and the fruits have 

 shorter pedicels and short but distinct styles. The somewhat angular 

 branchlets seem to indicate that a species of the B. vulgaris group may be 

 the other parent. Whatever its origin this hybrid is a noble plant well 

 worth cultivating.
