GEOGRAPHY AND VEGETATION OF NORTHERN FLORIDA. 405 



0,1 Acer Floridanum (Chapm.) Pax. Sugar-maple. 



Rich calcareous woods, mostly in regions i and 3. 

 o Acer Negundo L. Box-elder. 



Along Apalachicola River, and in hammocks in central Florida. (As these 



two habitats are quite different, and also pretty widely separated, there may 



be two species involved, but botanists have not yet distinguished them.) 

 Sapindus marginatus Willd. 



Phosphatic (?) hammocks around Alachua Sink. 

 Tilia Floridana Small. (Lin, or basswood.) 



Rich woods and bluffs near Apalachicola River, Jackson and Gadsden Cos. 

 0.1 Tilia pubescens Ait. 



Mostly in low or phosphatic hammocks, in regions 10, 13, etc. 

 0.2 Gordonia Lasianthus (L.) Ellis. (Red, tan, or loblolly bay.) 



Bays and non-alluvial swamps; rare west of Suwannee River, common east 



of Trail Ridge. 

 o.i. Persea Borbonia (L.) Sarg. (Red bay.) 



Hammocks ; commonest eastward. 

 Persea pubescens (Pursh) Sarg. (Red bay.) 



Non-alluvial swamps, etc. ; widely distributed but rather scarce. 

 ? Persea humilis Nash. 



Scrub in the peninsular lake region. 

 0.1 Sassafras variifolium (Sal.) Kuntze. Sassafras^ ' 



Arborescent in the Wakulla hammock country. Elsewhere usually a shrub 



in old fields. Rare in East and West Florida. 

 Nyssa sylvatica Marsh. Black gum. 



Clayey uplands, mostly northward. 

 2.0 Nyssa biflora Walt. Black gum. 



Non-alluvial and estuarine swamps and shallow ponds. 

 0.2 Nyssa uniflora Wang. (A'', aquatica L. ?) Tupelo gum. 



Swamps and sloughs, from Choctawhatchce River to Wakulla Co. 

 0.2 Nyssa Ogeche Marsh. Tupelo gum. (Ogeechee Lime.) 



Swamps and sloughs, especially of lower Apalachicola River. 

 0.9 Cornus florida L. Dogwood. 



On loamy uplands, in shade of other trees. 

 ? Cholisma (originally misspelled Xolisma) ferruginea (Walt.) Heller. 



Sandy hammocks and scrub, Middle and East Florida; usually no more than 



a shrub. 

 0.1, Oxydendrum arboreum (L.) DC. Sourwood. 



Loamy uplands, north of lat. 30° and west of Suwannee River. 

 ? Batodendron arboreum (Marsh.) Nutt. Sparkleberry. 



Sandy hammocks and other dry places protected from fire. 

 ? Diospyros Virginiana L. Persimmon. 



Old fields, etc. ; common, but perhaps not native, and often little more than 



a shrub. In the vicinity of Tallahassee its fruit begins to ripen about the 



last week in August, notwithstanding the old tradition about persimmons 



and frost (which probably originated in Virginia, and may be true there), 

 o Bumelia lycioides (L.) Gaert. 



Calcareous bluffs of Apalachicola River. Gadsden Co. 

 ? Bumelia lanuginosa (Mx.) Pers. 



Sandy hammocks mostly.
