 Wales (w. H. PEAESON, April, 1877). 



C. Macounii Aust., proximo affinis, distat colora viridi; caule tenui 

 crebre ramoso ; foliis subimbricatis sinu plerumque lunulato, lobis apic- 

 ulo' lunguiformi carentibus, cellulis subquadratis ; foliolis nullis. — C.

 ultra J fissis, lobis exunguiculatis, cellulis quadratis reticulatis (nee 

 guttulatis). 



Through the kindness of the discoverer I am enabled to add this new species to 

 my list. It differs essentially from C. divaricata in being still more minute ; in the 

 deeply bifid leaves whose narrow segments end in a claw-like apiculus, the guttulate 

 areolation, and especially in the cladogenous inflorescence (which brings it ne^r C. 

 Macounii). — A plant gathered lately by Messrs. Pearson and Stanley, in similar sites 

 near Beddgelert, seems distinct by the greener colour ; the leaves cloven only to the 

 middle, with broader segments wanting the apiculus, the frequently denticulate 

 margins and the reticulate cells; and it is possibly distinct also from C. divaricata.
