To the botanist this is one of the most interesting regions in 

 Florida. The two representatives of the yew family, Tumion taxi- 

 folium (formerly Torreya taxifolia) and Taxus Floridana, do not 

 grow wild anywhere else in the world, as far as known, not even in 

 the same region in Georgia. A good deal has been written about 

 the former,* but very little, strange to say, about the latter, which 

 according to the percentage figures given above is forty times rarer. 

 One of the shrubs, Clinopodimn dentatum, is likewise endemic. 



Several other species in the list are not known elsewhere in 

 Florida, most of them being commoner much farther north. Among 

 these seem to be Dirca, Xanthorrhiza, Croomia, Syndcsmon, 

 Hypericum aureum, Campanula, Euphorbia commui^ata, Trillium 

 lanceolatum, Alsine pubera, Dentaria, and some rarer species not 

 listed; most of which prefer cool, rich woods with plenty of humus. 

 Platanus, Populiis, Acer saccharinum, Quercus pagodaefolia, 

 Bnmelia lyciodes, Arundinaria macrosperma, Kalinia latifolia, 

 and Selaginella apiis seem to extend into Florida only or chiefly 

 along the Chattahoochee-Apalachicola River. 



There seem to be more species of trees here than in any equal 

 area in northern Florida. About 55% of the forest is ever- 

 green, 7.1% of the shrubs are Ericaceae, and about 2% 

 of the herbs are Leguminosae ; all of which figures are below the 



*Those who have imagined that the Tumion was in danger of extinction 

 will be interested to learn now that it stands seventh in the list of trees, 

 and seems to constitute about 4 per cent of the forest.
