But different as these a ies are among them- 
selves they have a character in in common, which 
distinguishes them from all our Apaocionn 
Grape seeds; their beak is narrower and usu- 
ally longer, and their large chalaza (the area 
on the back of the seed) occupies the upper 
pide and not the centre of the seed; in the 
can species the beak is shorter and more

following cuts are not plain enough. 
The size and weight of the seeds varies 
greatly in the different species, thus Labrusca 
and Candicans have the largest, Cinereaand Ri- 
paria the smallest seeds, but even in the wild 
state we find variation, e. g., in phaptouiniges still 
more in Cordifolia, aud mos in FRiparia. In
