The following trees which are more or less common in other regions in the 

 same latitude are rare or absent in the northern part of the lake region : — 

 Finns echinata (short-leaf pine), P. glabra (spruce pine), Taxodium (cypresses), 

 Chainaecyparis (juniper"), Juiiiperus (cedar), Hicoria (hickories), Salix (wil- 

 lows), Ostrya. Betiila (birch), Fagns (beech), several species of Quercns (oaks). 

 Morns (mulberry), Ulmtis (elms), Celfis, (hackberry). Mains (crab-apple), 

 Crataegus (haws), Frunus (plums), Cercis (redbud), Ilex opaca (holly), Tilia 

 (lin, basswood), Nyssa (black and tupelo gums), Cornus florida (dogwood), 

 Oxydendrnm (sourwood), and Halesia. Most of these seem to be partial to 

 clayey, calcareous pbosphatic or alluvial soils, and their absence is thus easily 

 explained. Weeds are likewise scarce, on account of the small amount of 

 cleared land. 



Fersea humilis, Carberia, and several herbs too rare to appear in the above 

 list are almost confined to the lake region, and their usual habitat is the scrub. 

 Chapviania, a characteristic though not verv common plant of the high pine 

 land, is confined to Florida, but grows in the lime-sink region as well. Finns 

 clausa is almost confined to Florida, but grows along the coasts, like several other 

 scrub plants. (Farther south in the lake region there are many plants peculiar 

 to it.)
