1870.] EATON — HERBARIA OF LINNE AND MICHAUX. 25 



The Lunaria of the Sp. PI. p. 1519 is unquestionably the species 

 we now call by that name. It is, however, not a little singular 

 that Linnd should have had both the American and European 

 forms of the 0. ternatum of Thunberg without recognizing them 

 as distinct from his Lunaria. — W.] 



" OsMUNDA VIRGINIANA " — is the true Botrychium virginia- 

 num, one frond from Kalm (being marked " K ") and one from 

 Clayton (?) marked " Lunaria matricariae-folio Clayt. n. 706." 



OsMUNDA REGALis — One unnamed frond from Kalm is put 

 next to another that is marked 0. regalis. 



" OsMUNDA Claytoniana " — two fronds of this species in 

 which the fructification is 7iot terminal, but the upper sterile 

 pinnae are unexpanded, as noted by Dr. Gray long ago, and 

 recently by Dr. Milde. 



*' OsMUNDA ciNNAMOMEA " — one fertile and one sterile frond 

 from Kalm ; very good. 



" AcROSTiCHUM POLYPODioiDES " — is the PoJypodium in- 

 canum of Swartz. 



" AcROSTiCHUM AUREUM " — vcry good. 

 AcROSTiCHUM AREOLATUM — Sp. PL p. 1526, not found; 

 the Woodwardia angustifolia of Smith is the plant described. 



ACROSTICHUM PLATYNEURON — p. 1529, not found ; the 

 plant described is Asplenium eheneum. 



'' ACROSTICHUM ILVENSE " — is our North American Woodsia 

 obtusa. 



[Here Linne appears to have confounded our particularly 

 distinct Woodsia ohtusa with his Ilvense, and to have missed 

 describing another good North American species. There is no 

 doubt that the Ilvense of his writings is that of modern 

 botanists. — W.] 



" ACROSTICHUM EBENEUM " — is Gymnogramme calomelanos 

 small form, or possibly G. tartarea ; a West Indian fern. 



" Pteris aquilina " — very good. 



" Pteris caudata " — one frond, very delicate, is good cau- 

 data ; one with very broad segments is a caudate but not uncom- 

 mon form of aquilina. 



"Pteris atropurpurea " — one frond from Kalm of our 

 Pellcea atropurpurea. 



-'■ Asplenium rhizophyllum " — is Camptosorus from Kalm ; 

 three fronds from one root, and one frond with auricles 1^-2^ 

 inches long.
