Leguminosae are well represented, and in fact the members of 
this family predominate among the herbaceous plants. Chap- 
mania Floridana, Aeschynomene hispidula, Morongia angustata, 
Rhynchostia cinerea, Crotalaria Purshii, Cracca ambigua and C. chry- 
Sophylla are the ones met with everywhere. Among the more 
frequent of the Compositae are Berlandiera subacaulis, Pterocaulon 
undulatum, Cuicus spinosissinus Elliottii, Lygodesmia aphylla, Ver-" 
nonia angustifolia, Hieracium megacephalon, Helianthella grandi- 
Jlora and Liatris secunda. Among other plants characteristic of 
this region are: Tvadescantia rosea, Asclepias amplexicaulis, 
Asimina pygmaca, Commelina angustifolia, Polanisia tenuifolia, 
Breweria angustifolia, Stilingia sylvatica, Croton argyranthemus, 
Jatropha stimulosa, Eriogonum longifolium and E. tomentosum, Por- 
tulaca pilosa, Ceanothus microphyllus and Pirigueta Caroliniana. The 
grasses are represented by few species, but these occur in great 
numbers. Aristida stricta, Sporobolus juncea, Andropogon argy- 
vaeus and A. longiberbis are the commonest. There is only one 
member of the Cyperaceae that occurs in any quantity and that is 
Stenophyllus Waret. 
The high pine land is subject to annual fires. The cattle 
growers burn off the old grass, so that the roots will start up and 
give a crop of young, succulent shoots. It is wonderful what a 
variety of features protect the plants against these destructive 
fires. Pinus palustris has a very thick bark at the base of the 
trunk, and the thickening is very noticeable in the shape of a sud- 
den swelling just above the ground. All the herbaceous plants 
have large underground parts, tubers or thick roots, which 
store up nutriment and protect them. Commelina angustifolia 
has an immense fascicle of fleshy horizontally spreading roots, 
which anchor the plant deep in the ground and keep its 
soft, tender parts out of harm’s way. Tradescantia rosea has a 
similar arrangement. The provision for the preservation of Hfe/t- 
anthella grandiflora from extinction is even more noticeable. 
Buried in the ground, 6 or 8 inches deep, is an oblong tuber; 
the stem arising from this, instead of pushing abruptly upwards, 
continues horizontally, sometimes for a distance of 12 or 18 inches, 
and then rises obliquely to the surface; no matter how much the 
fire may damage the aerial portions, the plant has a supply of nu-
