BOTANICAL INFORMATION. 295 



American Botany, should be recorded in the pages of our 

 Journal. At the head of them, justly stands Mr Nuttall, to 

 whom the authors are indebted (independently of the im- 

 mense mass of information derived from his valuable publi- 

 cations, which are known wherever Botany is studied), for 

 a nearly complete series of the plants collected during Jiis 

 recent journey aci-oss the Rocky Mountains to Oregon and 

 California, accompanied with manuscript descriptions of his 

 new genera and species, and also for many plants obtained 

 during his travels in Arkansas in the year 1819. The Aca- 

 demy of Natural Sciences at Philadelphia, afforded the 

 opportunity of examining the chief collections of Mr Nuttall, 

 those of Mr Von Schweinitz of Mechlenberg, and Professor 

 Benjamin Smith Barton. The daughter of the lamented 

 Elliott sent whatever was needful for examination of her 

 father's Herbarium; and Dr Bachman, and Professor Gib-

 that fertile territory. Professor Bigelow, B. D. Greene, 

 Esq.) Mr E. Tuckerman, Mr Oakes, Dr Jacob Porter, Mr 

 T. A. Greene; Professors Hitchcock, Emmons, and Dewey, 

 sent the productions of Massachusetts, of Maine, and New 

 Hampshire; Dr Barratt of Middleton, Connecticut, distin- 

 guished by his knowledge of North American iVilloics, com- 

 municated specimens from that neighbourhood, and from the 

 White Mountains of New Hampshire, and Professor Tully 

 from the vicinity of Yale College. Plants of the state of New 

 York, most of which must have been already familiar to the 

 authors themselves, have further been supplied by Dr Steven- 

 son, Dr Bradley, Dr H. P. Sartwell, Mr David Thomas, Dr 

 Crawe, Dr Aikin, Professor Lewis, C. Beck, Mr K. J. Down- 

 ing, Professor Bailey, Mr William Cooper, Mr Halsey, Pro- 

 fessor Eaton, Mr R. J. Brown, and Mr John Carey. Of the 

 plants of Pennsylvania and New Jersey, the chief contribu- 

 tors have been Dr Pickering, Mr Durand, and Dr Darling- 

 ton. Of those of Virginia, the Rev. Professor RufFner. For 

 plants of North Carolina, ihey are chiefly obliged to the 

 Uev. Mr M. O. Curtis, the late Mr Von Schweinitz, and to
