SOME EARLY PHILADELPHIA BOTANISTS; SCHWEINITZ, NUTTALL, RAF- 



IKESQUE AN^D DARLINGTON. — W. E. Leonard. 



SCHWEINITZ. 



The Rev. Lewis David von Schweinitz, whose name is identi- 

 fied with some 200 species of plants, and 1,200 s})ecies of fungi, 

 was practically a Philadelphian, although a resident of Beth- 

 lehem, Pa. 



He was born at the latter place, February 13th, 1780, and died 

 in the same, February 8th, 1834, lagkiiig but five days of com- 

 pleting his fiftyfourth year. 



At 18 years of age he went to Germany for his education, and 

 returned when 34 years old (in 1812) as a Moravian minister to 

 Salem, N. C, and nine years later to his native town of Bethle- 

 hem. 



Of his life I am not able to learn many particulars,but the re- 

 sults of his in<^iessant labor are left for us to contemplate. 



As mentioned above he added 1,400 entirely new species to 

 Botany, 1,200 being North American fungi. His printed works 

 are as follows: — Conspectus Fungorum Lusatiae — Leipsic, 1805 

 Synopsis Fungorum Carolinae Superioris — Leipsic, 1818, edited 

 by Dr. Schwargricken — Specimen Florae Araericae Septan tionalis,.
