NEW SPECIES or GIUMMIA, 
terminations qf the leaves, gives an appearance to the plant 
that belongs not to any other, particularly when viewed 
covering a large surface of rock. 
This species had for some time been mistaken for G. 
ovata^ and, without examination, I sent a quantity of it, 
under that name, to Mr Hobson of Manchester*, who re- 
turned me an answer, denying that it was G. ovata, and sus- 
pecting it to be pulvinafa ; an attentive examination pro- 
duced the above result. It has not yet been detected in 
any other place, which is the more extraordinary, on ac- 
count of its great abundance in the King''s Park.
