178 Mr. J. Miers on several genera hitherto placed in Solanacer. i 
to which will be subjoined a review of the several new genera 
that have presented themselves in the course of this inquiry. To 
these details will be added the description of such of the genera 
of the Atropacee as have not yet been described by me, and the 
whole will offer a large accumulation of novel facts, that probably 
may serve to facilitate the labours of the able botanist now en- 
gaged in a monograph of this large family, which has hitherto 
been so little studied. 
In these investigations I have been carried far beyond the line 
originally intended, having been tempted to proceed by the 
abundant materials that have presented themselves to my notice, 
principally derived from the rich herbarium of Sir Wm. Hooker, 
to whose kind liberality I am mainly indebted for the opportu- 
nity of bringing to light so large an accumulation of new facts. 
The following synopsis will be sufficient to exhibit the proposed 
arrangement without farther explanations.
