This list is merely intended as a rough guide and not a complete list of the things which have been or are being cultivated in the territory covered by this work. It contains the plants that the writer has tried sufficiently to form some idea as to what they may be expected to do here; those that have come under his notice in the grounds of others, and most of those that have been cultivated in the state of which he has authentic information. A considerable number of species have been grown here of which the writer has had only hearsay information and these, for the most part, have not been discussed. In a few cases I have mentioned plants that, so far as I know, have not been introduced; things of considerable importance which ought to be tried here.

I have not attempted to follow the nomenclature adopted by any one. No two authors agree in the names they use for any set of plants; in fact, no author that I know of agrees with himself if he publishes the same list more than once. I have made no attempt to use the latest applied names; in order to do this it would be necessary to have access to extensive libraries, and the latest names only hold good until someone publishes again.

The descriptions in many of the botanies and plant encyclopedias are lamentably brief and unsatisfactory and in numerous instances where keys are given they do not lead the student to the plant he is trying to identify. I have not attempted to describe the species here listed as, in order to do so, it would be necessary to extend the work beyond reasonable limits, but I have pointed out in. many cases the most obvious characters of the plants discussed. The arrangement followed here is essentially the same as that used in my Plants of Dade County.
