Nearly the whole of these Willows, (except S. arenaria, 
from Scotland), are from Riehmond, Yorkshire, and chiefly 
gathered by Mr. Ward, * who has observed them for many 
years in their places of growth, and very few persons have 
bestowed more patient study upon this tribe of plants, or 
attained to greater skill in discriminating them." 
The editor has been surprised, in the course of his investi- 
gations, to observe the number of monstrosities, or rather of 
more or less perfect changes of sex, in the specimens collected, 
and this subject he thinks highly worthy of careful attention. 
* According to Fries, the female sex is only found as you ap- 
proach the northern or cold, and the male towards the southern 
or warm, limits of the different species; and that author is 
disposed to consider the circumstance as the result of climate, 
a singular instance of which he quotes from the FI. Ratisb. 
1829, p. 422. From a female tree of S. Babylonica, a male 
branch was produced, after the very hot summer of 1826, and 
from this a male tree has grown."

Of this work we have already noticed the scope and 
object, to the conclusion of the second volume. It follows 
the arrangement of De Candolle, and, excluding the Sup- 
plement, terminates with the 130th Order, Monotropeæ. 
Thus far the work may be considered supplementary to the | 
Prodromus of De Candolle. It now assumes a different
