nor parts, to which it is well to attach easily remembered
names. In this section of my index I will not admit the confusion of idea
involved by alphabetical arrangement of these names, but will sacrifice
facility of reference to clearness of explanation, and taking the four
great parts of the plant in {239} succession, I will give the list of the
minor and constituent parts, with their names as determined in Proserpina,
and reference to the pages where the reasons for such determination are
given, endeavouring to supply, at the same time, any deficiencies which I
find in the body of the text.

I. THE ROOT.

PAGE

Origin of the word Root 27

The offices of the root are threefold: namely,
Tenure, Nourishment, and Animation 27-34

The essential parts of a Root are two: the Limbs
and Fibres 33

I. THE LIMB is the gathered mass of fibres, or at
least of fibrous substance, which extends itself
in search of nourishment 32

II. THE FIBRE is the organ by which the nourishment
is received 32

The inessential or accidental parts of roots, which
are attached to the roots of some plants, but
not to those of others, (and are, indeed, for the
most part absent,) are three: namely, Store-Houses,
Refuges, and Ruins 34

III. Store-houses contain the food of the future
plant 34

{240}

IV. REFUGES shelter the future plant itself for a
time 35

V. RUINS form a basis for the growth of the future
plant in its proper order 36

Root-Stocks, the accumulation of such ruins in a vital
order 37

General questions relating to the office and chemical
power of roots 38

The nomenclature of Roots will not be extended, in
Proserpina, beyond the five simple terms here given:
though the ordinary botanical ones--corm, bulb, tuber,
etc.--will be severally explained in connection with the
plants which they specially characterize.
