INDEX OF NAMES OF PLANTS.

[In the following Index the names of the orders that are incidentally
mentioned are printed in small capitals, those of the genera and species
in ordinary type. The names are inserted as found in the several
records, &c., without in general any attempt having been made to
determine their accuracy. For this reason the authority for the specific
name is rarely given, such citations being here unnecessary if not
impracticable. It may, however, be assumed that the names made use of
are those generally adopted by naturalists.

This index will be found useful for statistical purposes. It will show
at a glance, at least approximately, how often certain genera and
species are affected with malformation, as contrasted with others. The
nature of the malformation may of course be ascertained by referring to
the particular page indicated by the number. The proportion of wild to
cultivated plants may also be approximately ascertained, and the effects
of cultivation estimated. The disproportionate frequency with which some
species are affected, e.g., _Trifolium repens_, &c., as contrasted with
other closely allied, and perhaps equally common species, under
apparently identical conditions, is also made manifest.]
