25. We will try, presently, what is to be found out of useful, or pretty,
concerning all these twelve violets; but must first find out how we are to
know which are violets indeed, and which, pansies.

Yesterday, after finishing my list, I went out again to examine Viola
Cornuta a little closer, and pulled up a full grip of it by the roots, and
put it in water in a wash-hand basin, which it filled like a truss of green
hay.

Pulling out two or three separate plants, I find each to consist mainly of
a jointed stalk of a kind I have not yet described,--roughly, some two feet
long altogether; (accurately, one 1 ft. 10½ in.; another, 1 ft. 10 in.;
another, 1 ft. 9 in.--but all these measures taken without straightening,
and therefore about an inch short of the truth), and divided into seven or
eight lengths by clumsy joints where the mangled leafage is knotted on it;
but broken a little out of the way at each joint, like a rheumatic elbow
that won't come straight, or bend farther; and--which is the most curious
point of all in it--it is thickest in the middle, like a viper, and gets
quite thin to the root and thin towards the flower; also the lengths
between the joints are longest in the middle: here I give them in inches,
from the root upwards, in a stalk taken at random.
