Tur figure which accompanies this. paper is of a new Caltha, 
which I had some time ago from Scotland by the kindness of my 
friend Mr. J ames Dickson, who, when he gave it to me, was of 
opinion that it would prove a new Species, which I am now 
well convinced it is, having cultivated it for several years. Tt 
differs from the Cc ; alustris in having a creeping stalk, 
shooting forth roots at the joints ; leaves triangular, very sharply 
crenated ; and the petals smaller, narrower, wedge-shaped and 
pate t cannot be the Caltha natans of Gmelin and Willde- 
now, which has a white flower, procumbent stalk, and floats on 
the -— nor Caltha minor of Miller's Dict. ( palustris @ Willde- 
which does not appear to differ from C. palustris in any re- 
spect but size. In Dr. uen MSS. in Sir Joseph Banks’s 
cribed and named, and in the 
"C „imens of three others from the North- 
west coast of Am where they were found by Mr. A. Men- 
zies, who I hope. x us descriptions of them. The 
following may sen for the specific differences of the Calthe al-
