I cannot agree with the authors who unite these two plants. 
If intermediate states are to be considered as a sufficient ground 
for uniting what have hitherto been considered distinct species, 
then must a great many more of the Cladonie be united than is 
now done, for between the greater part of the different species in. 
this genus there are so many intermediate states, that it is ex- 
tremely difficult to know to what species to refer many speci- 
mens. Manufacturers have noticed that the tinctoria is very 
superior as a dye to the fuciformis, and my friend Mr. Lukis has 
_ pointed out to me a distinction between these two plants which 
I was not before aware of, but which the examination of a great 
number of specimens enabled me to confirm ; viz. that the sap of 
tinctoria is of a deep yellow, staining the fingers when gathered, 
whereas that of the fuciformis is not so. It is perhaps to be re- 
gretted that chemical tests have not been resorted to in endea- 
thew e eee Lares gee as ge eas
