IV PREFACE. 



ining the vegetable productions of the inter- 

 esting regions through which he passed. His 

 earlier botanical papers are inserted in the 

 American Journal of Science. In 1833, in 

 connexion with Dr. Loomis, he published the 

 first edition of this catalogue. The present 

 greatly improved edition was prepared by 

 Mr. C. alone. His principal herborizations 

 were conducted in the vicinity of Newbern ; 

 and in Middle Florida, particularly in the 

 vicinity of Tallahassee, and along the Appala- 

 chicola river. We are indebted to him for 

 many important contributions to the Flora of 

 North America ; but his disinterestedness and 

 modesty prevented him from publishing the 

 greater number of his own discoveries. Most 

 of his new and rare plants, together with his 

 valuable observations on them, w T ere kindly 

 presented to me, with permission to use them 

 for the benefit of science. It is my purpose 

 to describe some of these in a separate paper. 

 He has, however, given us a valuable mono- 

 graph of the genus Sarracenia, which will 

 appear in the forthcoming volume of the An- 

 nals of the New- York Lyceum.
