1918] Blake,— On some Species of Viburnum 11 
ON THE NAMES OF SOME SPECIES OF VIBURNUM. 
S$. F. BuaKke. 
For many years a small Viburnum of the V. dentatum group, 
strongly marked among our New England species by its very short- 
petioled leaves and prominent stipules, has been known by the name 
Viburnum pubescens Pursh,! based on V. dentatum B. pubescens Aiton.” 
While working at the British Museum in 1915, I had an opportunity 
to examine not only the type of Aiton, on which the specific name must 
rest, but also the Solander manuscript of the Hortus Kewensis; and 
the study of this material shows that the name V. pubescens can by 
no means be used for the plant which has borne it so long, but must be 
applied to the species which was described by Britton? in 1901 as 
Viburnum venosum. | 
In the Solander MSS. Viburnum dentatum and its varieties are twice 
dealt with, once on pages 761-763 of volume seven, and again on 
pages 765-767 of the same volume. The second of these treatments, 
which is the important one for the determination of the application of 
the name V. dentatum var. pubescens, runs as follows:
