Cal- On the oppofite fide of that ditch, 
tba " you fee a yellow flower, fomewhat 
larger than this, apparently of the Ra- 
nunculus genus. It is indeed of the 
fame Clafs and Order, viz. Polyandria 
Polygynia, but differs from the Ranunculi 
in having no calyx, no netfarium, and 
in its feeds being inclofed in capfules. 
It refembles the Ranunculi in having 5 
rounded petals j but they are not glaz- 
ed on the upper fide. The flowers 
grow in pairs on feparate/Wwflcw//. The 
leaves are heart-(haped. It is the Cal-

genus hitherto found in any part of 
the world. You will find them in al- 
moft every fwamp, and particularly in 
very great abundance on the morafs at 
the back of Peter-houfe.
