GEOGRAPHY OF CENTRAL FLORIDA 79

 To save space and avoid boring readers not interested in botanical matters the plant lists are made rather short, omitting the rarer species that one would not be likely to encounter every day, though in a few cases the lists have been extended just far enough to take in certain species that are especially characteristic. The trees listed in each case are probably only about half the number of species represented in any region, but they make up at least nine-tenths of the bulk of the forest. The shrubs and herbs are listed less completely, partly because they are less important, and partly because some of them cannot be identified any day in the year as the trees can, and the writer has not yet explored this area in the fall months, where, many herbs bloom that would hardly be noticed in the spring.
 For each plant there is given its technical name, its common name (if any), and its usual habitat expressed in a word or two. The technical names of evergreens are printed in bold-face type, and in the case of semi-%vergreens only the specific name (second word) is thus printed. There is some uncertainty as to just which herbs should be classed as evergreens, partly because some of them have not been sufficiently observed in winter, and partly because it is impossible to draw a sharp line between evergreens and non-evergreens. Some herbs whose leaves die down completely in winter farther north are partly evergreen in the area treated and entirely so farther south ; and many that are not ordinarily thought of as evergreen have rosettes of leaves close to the ground that live through the greater part of the winter.
 The technical names of weeds and other plants that seem to grow only in places that have been more or less disturbed by civilization are enclosed in parentheses. Good examples of plants which are ordinarily regarded as indigenous but behave rather suspiciously are the two tall doz-fennels, Enpatoriuni conipositifoliuni and E. capillifoliun. The former is sometimes seen in apparently tindisturbed high pine land, but it is ibore characteristic of roadsides or even dirn trails made by log-carts, and abundant in old fields. The latter is common in lake basin prairies. etc., but may not have been there in prehistoric times, when such places were not closely pastured as they are now.* Amon- the trees the persimmon, a sunposed native: is far more frequent in 'tultivate(l or abandoned fields than it is in swamps, which may be its natural habitat.
