NOTES ON SOME OF THE PLANTS IN THE 

 HERBARIA OF LINNE AND MICHAUX. 



By Daniel C. Eaton, M.A., Professor of Botany in Tale College. 



Prof. Eaton, of New Haven, U. S., the eminent American 

 Pteridologist, when in Europe on a visit in 1866, examined 

 many of the standard herbaria, and made notes on the American 

 plants contained in them. He has most liberally placed a series 

 of these notes on the North American Filices in my hands for 

 perusal, has allowed me to take copies of them, and to print such 

 selections from them as I might deem of sufficient interest : those 

 relating to the collections of Linne, now in London, and of 

 Michaux, in Paris, are here given. The herbarium name of 

 each plant is placed within quotation marks, as is also such notes 

 (of habitat, etc.) as were deemed of sufficient interest to be 

 copied from the sheets to which the respective specimens were 

 attached. Mr. Eaton's observations follow. I have not printed 

 these verbatim, as, not being intended for publication, they were, 

 more or less, made up of indications and signs which I have 

 attempted to write out with exactness. One or two observations 

 of my own are placed within brackets, and bear my initial. For 

 convenience of reference I have arranged the species in the order 

 of their occurrence in the Species Plantarum, and in the Flora 

 Boreali-Americana. D. A. Watt. 



THE LmN^AN" FILICES. 



Notes made in the hall of the Linnean Society, London, 

 August 7, 1866:— 



*'Onoclea sensibilis " — one sterile frond and one fertile 

 frond of the true plant. 



" OsMUNDA Pensylv." — a short sterile leaf of perhaps Stru- 

 thiopteris or probably of Osmunda Claytoniana ; veinlets once 

 and twice forked, segments broad and round, the lowesi) pinnae 

 lono- as any. (It cannot be Struthiopteris, and perhaps is not 

 Osmunda, but some Aspidium. D.C.E., anno 1870.) 



" Osmunda Lunaria " — consists of two fronds of oar Botry. 

 lunarioides and one frond B. rutcefolium (A. Braun)— the latter 

 very much like the former, and (by its ticket) from Petropolis. 

 There is no true Lunaria in the herbarium. / 



ITt must be borne in mind that the ancients were very 

 careless about their plants, and very careful about their books.
