7. A. ebeneum, Aiton, 



Hort. Kew. iii. 462; A. trichomanoides, Michx. 265. 



8. A. marinum, Linn. 1540. 



Attributed to the Lower Provinces by Sir Wm. 

 Hooker, — probably in error. 



9. A. angustifolium, Michx. 265. 



10. A. thelypteroides, Michx. 265. 



Athyrium, Eoth. 

 1. A. Filix-fcemina (Linn. 1551). 



Both, Fl. Germ. iii. 65 ; N. filix-f. and N. asple- 

 nioides, Michx. 268 ; also Aspd. angustum, Willd., 

 Pursh 664. Perhaps an Asplenium. 



Tribe Aspidie^:. 

 Phegopteris, Fee. 



1. P. Dryopteris CLinn. 1555). 



Fee, Gen. Fil. 243. Nephrodium D., Michx. 270. 

 (Mr. Moore refers Michaux's plant to the next 

 species.) 



2. P. Eobertiana (Hoffm.). 



P. calcarea, Fee, 1. c. 243; Polypodium ealca- 

 reum, Smith ; doubtfully distinct* from I'. Dry- 

 opteris. Universally but erroneously attributed to 

 North America. 



3. P. connectile (Michx. 271). 



Polypodium Phegopteris, Linn. 1550; P. con- 

 nectile, Willd. 200, Pursh 659. Michaux's name 

 ought to be restored to this plant; it has priority 

 over those of Fee or Mettenius. 



4. P. hexagonoptera (Michx. 271). 



Fee, Genera Filicum, 243. 



5. P. rhsetica (Linn. 1552). 



P. alpestris, Mettenius ; Polypodium alpestre, 

 Hoppe; Aspidium riueticum, Sw'irU 59. Cascades ; 

 RoC&y Mts. 49 Q N. Lat,, Dr. Lyall. 



[P. montana (Yolger). 



More properly Aspidium montanum ; though it 

 has been placed here by Fee.] 



Aspidium, Swartz. 



Polystichum, Roth. ; Dryopteris, Adanson. 



§ Dryopteris (Schott) A. Gray. 



Lastrea, Presl ; Nephrodium, Richards, 11. 

 Brown, Hooker; Polystichum, D.C., Koch, Le- 

 debour. 



1. D. Thelypteris (Linn. 1528). 



Gray's Manual, Ed. 1st. 630. 



2. D. Nov-Eboracensis (Linn. 1552). 



Gray, 1. c. 630, N. thelypteroides, Michx. 267. 



3. D. montana (Yolger). 



Aspd. Oreopteris (Ebrhart) Swartz 50. Mr. 

 Moore says that Asprdum montanum has been 

 found in Vermont — certainly an error. 



4. D. spinulosa-dilatata. 



Polypodium dilatatum, Hoffman ; Aspd. dila- 

 tatum, Swartz 420 ; and A. dumetorium, Willd. 

 2(13. D. dilatata, Gray, 1. c. 631. Dr. Gray justly 

 considers this fern (which is common in eastern C. 

 E.) to be merely a variety of Aspidium spiiudosum 

 Swartz. 



5. D. spinnlosa-vera. 



Polypodium spinnlosum Betzius; Aspd. s. 

 Swartz 54, 520 ; A. intermedium, Willd. 262. 

 Common west of Quebec. 



6. D. spinnlosa-remota. 



Aspd. remotum, A. Br. ; Nephrodium r. Hook. 

 Br. Ferns, t. 22; Aspd. Boottii, Tuckerman. Dr. 

 Gray refers Dryopteris remota here (as A. spinn- 

 losum var. Boottii)— it may prove to be a distinct 

 species; it is not well known to me. 



7. D. eristata (Linn. 1551). 



Gray, 1. c. 631 ; A. Lancastriense, Sprengel, 

 Swartz 52. 



8. var. majus (Eaton). 



A. filix-mas, Pursh 667 ? 



9. D. Goldiana, Hook. 



Gray, 1. c. 631 ; A. filix-mas, Pursh 662 ? 



10. D. Filix-mas (Linn. 1551). 



Schott, Gen. Fil. t. 9. Bocky Mts. 



11. D. marginale (Linn. 1552). 



Gray, 1. c. 632. 



12. D. arguta (Kaulf. 242). 



N. rigidum var. American um, Hook. Sp. Fil. 60. 



13. L>. rigida (Hoffin.). 



Not of Gray, 1. c. 631. A. rigidum, Swartz 53. 

 Attributed to North America by Mr. Bentham— 

 doubtless in error. 



§ PohjsticliHin, Schott, 



Presl, A. Gray ; Aspidium, Bichards, B. 

 Brown, Ledebour. 



1. P. fragrans (Linn. 1550). 



A. fragrans, Swartz, 51. In technical characters 

 this plant is more properl}- /Jri/opUris jhnjraus, 

 and is so considered by Hooker, Ledebour, ete. I 

 agree with Dr. Gray in considering that its natural 

 affinity places it lure. 



P. aculeatnm (Linn. 1552). 



A. aculeatnm and A. lobatum (Aiton) Swartz 

 53, and A. angulaiv, Willd. 2J7. The typical form 

 (A. aculeatum, Willd. ete.) lias not been found in 

 North America. Mr. Moore's remark—" extends 

 " from the eastern U. S. to Columbia on the north- 

 " west coast"— is certainly an error. "We have, 

 however, two well-marked and constant varieties. 



2. var. Bramiii (Koch). 



A. Braunii, Spenuer; P. Braunii. Fee; which is 

 allied to the European Aspidium aculeatum var. 

 annulare.
