frequently fumifhed with a green longitudinal ftreak running through them.— 

 The form of thefe fpots is in general almoft elliptical, but fometimes tends to glo- 

 bular; and, as above mentioned, they take in their latter ftage a fingular ftellated 

 appearance : the fpace alfo that they occupy in the joints is far from certain, for 

 fometimes they fdl nearly the whole, and at others only a fmall portion of them. 



Fig. D. reprefents what I fuppofe to be a variety of C. bipundtata, though it 

 may poffibly hereafter prove to be a diftinit fpecies ; I found it abundant on 

 Finchley Common, in March, 1802, in company with my friend J. Woods, jun. 

 and both from its brown colour and the fingular formation of its fpots, it differed 

 remarkably from the general appearance of the plant.
