140 THE BOTANISTS OF PHILADELPHIA: 



A similar honor was conferred on Dr. Darlington in 1825, 

 by Professor De Candolle, of Geneva, for his eminent 

 services to botany. The genus dedicated to him by De 

 Candolle did not, however, prove to be sufficiently distinct 

 to maintain its place as an independent genus, and his 

 friend, Professor Torrey, of New York, dedicated to him a 

 new and splendid genus {Darlingtonia) of California plants, 

 of the natural order Sarraceniacese, which, from its rarity 

 and beauty, constitutes a worthy and fitting compliment to 

 an industrious laborer in the agreeable fields of botanical 

 science. In 1826 Dr. Darlington published a small book, 

 called by him " Florula Cestrica," and later, in the year 

 1837, published his " Flora Cestrica," * a description of 

 the flowering plants of Chester County, which was a new 

 edition of his former work, much enlarged and greatly 

 improved. The work is regarded as one of the most com- 

 plete local Floras extant, and is a model for all works of a 

 similar character. The first addition of the work was 

 arranged according to the Linnsean System of classification, 

 but the Natural System was adopted for the later editions. 

 Conceiving the idea of assisting the farmers of our 

 country by a work expressly devoted to an account of those 

 plants which it more especially concerns them to know, he 

 prepared and published in 1847 his " Agricultural Botany," f 

 in which he described in plain and familiar terms not only 

 the useful cultivated plants, but all those which a careful
