NOTE ON THE TABLE OF FLOWERING SEASONS.

The following list of Flowering Seasons has been compiled from 3 years’ observations between 9° and 14° North Latitudes. No account has been taken of out-of-season flowering, which is of casual occurrence and due to various causes. The lengths of the flowering seasons are due chiefly to the wide distribution of the trees and do not necessarily represent the lengths of time individuals will bear flowers. Few species, in fact, bear flowers for longer than one month; many for only a few days, but a journey from north to south will show the effects of varying humidity on the flowering season. Such an influence may be counteracted by the date on which a fire swept through the country, fires exerting a quickening influence on the flowering to a marked degree.

The arrangement of the monthly columns so as to place the New Year in the middle of the page is made for the purpose of grouping the flowering period of those species which start flowering before January, whose periods would otherwise be broken up. Comparatively so few trees flower after June that the breaking of their periods is of little account.

This list will illustrate, also, the effect of fires at various times of the dry season on the different species, which may be more exactly determined by making an allowance for the situation of a forest in terms of degrees latitude. In this connection attention may be drawn to the large number of species whose fruits or seeds persist on the branches until the rainy season of the following year, and which will be destroyed by such fires. Only those species whose fruit forms and falls in the rains of the year in which it flowered will stand a fair chance of germinating.

Any observed extension, before or after the periods given here can be entered by extending the lines to correspond and suit the particular case.
