So great a fimilarity prevails between what are called C. dioica 
and capitata, that no author has as yet flruck out a conftant 
fatisfaétory difference of character. Mr: Hudfon's introduction of 
Linneus's C. capitata into the catalogue of Britifh plants, has ex- 
cited an enquiry into the reality of that fpecies, and in particular 
with refpe& to its being a native of Britain. Indeed the difference 
between them at moft feems very trifling. In C. capitata the fpike : 
is round, and fomewhat (owing to the male flowers at the 
top) conic: in the female C. disica, it is ovato-oblong. The 
capíules feem broader in capiiata. In dioica the ‘capfules are 
moft minutely ferrated towards the point; in capitata they are 
entire. In diea the capfules are ftriated with nerves, which 
can fcarcely be faid to appear in the very few fpecimens of capitata 
which I have feen. 1 have rer ae the male diosa with a female 
flower
