corded station for it — ,with the original discovery of AspkJium Ore- 

 qpteris in Unalaska by L. M. Turner; of Aspidium Mohrioides in 

 California by J. G. Leminon; of Cystopteris Montana, Aspidium 

 Lonchitis and Botryehium Lunar/a in Colorado by T. S. Brandegee; 

 of Notholosna Grayi in Arizona by W. M. Courtis; of Noiholcena 

 Lemmoni and N. nivea in the same territory by Lenimon; Cheilan- 

 thes Parishii in California by the Parish Bros.; the re-discovery of 

 Pellcm aspera in Texas by Dr. Edward Palmer, with many other 

 interesting discoveries which have been recorded from time to time, 

 marked this period, while recent collectors have so changed the sta- 

 tus of the southern and southwestern ferns that our previous lists 

 may now be reduced to the following, which will be interesting for 

 comparisons five or ten years hence : 



1. Notholaena ferruginea. 18. Bradleyi. 



2. tenera. 19. septentrionale. 



3. Cheilanthes leuoopoda. 20. cicutarium. 



4. microphylla. 21. Phegoptens alpestris. 



5. myriophylla. ? (As an- 22. Aspidium Lonchitis. 

 derstood by the writer) 23. fragraus. 



6. argentea. (Its actual 24. juglandifoliutn. 

 presence yet to be verified). 25. Cystopteris montana. 



7. Pelloea Breweri. 26. Woodsia hyperborea. 



8. Bridgesii. 27. glabella. 



9. aspera. 28. Trichomanes Petersii. 



10. pulchella. 29. Schizcea pusilla. 



11. ternifolia. 30. Aneitnia Mexicana. 



12. flexuosa. 31. adiantifolia. 



13. Pteris serrulata. 32. Botryehium boreale. 



14. longifolia. 33. Ophioglossuin nudicaule. 



15. Adiantumlricliolepis. 34. crotalophoroides 



16. Asplenium ebenoides, 35. palmatum. 



17. dentatum. 



Here we have a reduction of more than one half from the list 

 as given before, but to these may be added the more recent discov- 

 eries of 



36. Polypodium Swartzii. 



37. Notholama nivea. 



38. Grayi — plentiful enough in Arizona, but not fairly in distribution . 



39. Lemmoni— " " " " " " 



40. Cheilanthes Parishii. 



41. Asplenium serratum. 



42. . Tamitis lanceolata. 



43. AspkHum trifoliatum. 



44. Oreopteris. 

 45 conterminum. 



46. Woodsia Mexicana. 



47. Ceratopteris thalictroides. 



making a total number of 4.7 species which may be regarded as 

 rare ferns or which are not easily obtained at the present time. 

 The experience already recorded, however, justifies the belief that 

 many of these will be found plentiful enough when the regions 

 where they grow are more thoroughly explored, while the increas- 

 ing railroad facilities and communications are opening to the botan-
