28 BOTANICAL GEOGRAPHY, 



many peculiar plants grow only there. In the 

 Alleghanies they partake of the Canadian jflo- 

 ra, and in the White mountains of the Boreal 

 flora. 



4 The Prairie Regions of the West, with 

 few trees, but a profusion of fine plants, Dode- 

 catheons, Tradescantias, Helichroas, Gentians, 

 Radiate flowers, &c., some peculiar shrubs 

 and hardly any Acolyle plant. There the flo- 

 ral season begins in March or sooner as you go 

 South. 



5. The Limestone Region of Florida, with a 

 profusion of fine plants, Ludwigias, Rhexias, 

 &c. and many peculiar shrubs. 



6. The Limestone Region of the Ohio, form- 

 ing a bassin in Ohio, Indiana and Kentucky ; 

 it has a very scanty flora, few shrubs in the 

 woods, no Kalmias nor Vacciniums, but among 

 trees many Asiminas and Pavias, with abund- 

 ance of social grasses or congregated plants. 



7. The Apalachianand Wasioto Region, or 

 of the hills and mountains from Kentucky to 

 Georgia : this has a distinct flora from the Al- 

 leghanies and Florida shores, many Rhodo-

 fine plants; many yet new in the Unaka or Iron 

 mountains, the northern nucleus of it, as well 

 as in the peninsula of Florida, Alabama, &c. 



Besides these great localities I will add se- 

 veral smaller localities of great botanical inte- 

 rest by the numerous new plants which they 

 have afforded me. Every botanist knows some 

 similar place ; but those which I may boast to 

 have discovered or first well explored deserve 

 to be commemorated. They are 



1. The neighborhood of Quaker Bridge and Cedar Bridge in the centre 

 of the Pinelands of New Jersey— 2. The neighborhood of Mullica Hill in 

 4N'ew Jersey— 3. The sea Islands of New Jersey— 4. The source of the river
