120 PLANT LIFE OF ALABAMA. 
Most frequent on the low swells: 
Sieglingia chapmani. Andropogon virginicus glaucus. 
Chrysopogon nutans linnaeanus. Andropogon virginicus dealbatus. 
Andropogon elliott. Muhlenbergia trichopodes. 
Andropogon tener. Panicum longipedunculatum. 
After the ground has been once turned by the plow the glumaceous 
plants which formed the original sod disappear forever, the ground 
being taken possession of by carpet grass (Paspalum compressum), a 
West Indian species most probably introduced, and the creeping finger- 
grass (Syntherisma (Panicum) serotinum). Nearly all of the sundews, 
sarracenias, gentians, and other species already mentioned among the 
associations which inhabit the sphagnous bogs of the pine hills also 
enter into the associations of this semi-paludial Rynchsopora formation. 
During the latter part of January the Cuban pine unfolds its 
flowers, with Bartonia verna and Houstonia patens, and these are 
succeeded by the following: 
Chaptalia semifloscularis. Euphorbia inundata. 
Pinguicula lutea. Helenium vernum. 
Pinguicula pumila. Helenium helenium. 
Lupinus villosus. Helenium integrifolium. 
Helianthemum carolinianum. Polygala lutea.* 
Drosera capillaris. Polygala polygama.} 
Drosera brevifolia. Limodorum multiflorum. 
Drosera filiformis.+ 
The Pinguiculas mentioned are insectivorous plants common in the 
pine flats from North Carolina to Florida and Mississippi. Zuphorbia 
zcnundata is known only from the coast of western Florida and as far 
west as the eastern shore of the Mobile Bay near Point Clear. 
Remarkable is the occurrence of Zimodorum multifiorum in Mobile 
County (Fowl River Station). This beautiful orchid is otherwise 
known only from a few localities of peninsular and western Florida. 
It was first described by Chapman from the southern part of Florida 
and has been observed by the writer in the savannas near the upper 
waters of the St. Johns River. During the summer months bloom 
Linum floridunum, Polygala chapmani, Polygala hookeri, the latter 
two extending from western Florida to eastern Mississippi, and Zyga- 
denus glaberrimus, ranging from the pine flats of North Carolina to 
Louisiana, together with the following: 
Habenaria niveau. Centella. stricta. 
Cracca hispidula. Sabbatia gentianoides. 
Polygala cruciata} Pterocaulon undulatum (P. pycnostachyum 
Ludwigia hirtella.t Ell.). 
Ludwigia linearis. Dasystoma pedicularia.? 
Eryngium aquaticum. Gerardia paupercula. 
Eryngium synchaetum. Ascyrum stans. 
Eryngium ovalifolium. Ascyrum hypericoides. 
Hydrocotyle verticillata. Hypericum spp.
