MONTANA BOTANY NOTES 



MARCUS E. JONES 



After some four or five seasons spent in various parts of Montana, the 

 last two being in the vicinity of Flathead LaVce and the Sperry Glacier 

 region, in connection with the Biological Station work of the State Uni- 

 versity, it seems advisable to publish at this time the new species and vari- 

 eties discovered, and such changes of names as the critical field work has 

 proved are needed. To this list is added such plants as are found for the 

 first time within the Flathead drainage. 



Polypodium vulgare L. P. hesperium Maxon. This is found sparingly 

 from McDonald lake in the Mission mountains, to MacDougal peak, both in 

 the alpine and Middle Temperate life-zones, and also in the Sperry glacier 

 region. The high altitude forms are diminutive, but the plants growing 

 around Bigfork are the normal ones and show all sorts of intergrades. 



Phegopteris alpestris (Hoppe) Mett. This abounds in the alpine basins 

 of the Bitter Root mountains at Como peak and in the Sperry Glacier re- 

 gion. It has doubtless been overlooked from its resemblance to Asplenium 

 Filix foemina, and from its similar habit. 



Phegopteris polypodioides Fee. This grows at Gunsight pass in the alpine 

 basin of the lake, just south of Sperry Glacier. 



Cheilanthes Feei, Moore. A form of this, with slightly larger final divi- 

 sions grows sparingly at Mission Creek, and the Sperry Glacier; also found 

 on Silloway peak by MacDougal, and at Sperry Glacier by Williams. This 

 is wrongly referred by Rydberg to C. gracillima. 



Cryptogramme Stelleri (Gmei.) Prantl. This has been found at Camass 

 Lake by "Williams, at Lake McDonald by Umbach, and by myself at Mission 

 Creek. It grows in crevices of wet rocks, subalpine. 



Pellaea densa Brack is locally abundant at McDonald lake and on Mis- 

 sion Creek in the Mission mountains, Middle Temperate life zone. 



Asplenium viride Hudson. This is frequent on Mission Creek and at 

 Gunsight Pass, growing in crevices of rocks, subalpine. This is what Ryd- 

 berg wrongly refers to as A. Trichomanes. There are occasional stipes that 

 are nearly black. 



Polystichum Lonchitis van. scopulinum (Eaton Ferns. N. A. 2. 125 as acule- 

 atum var.). The most marked forms of this seem surely to belong to P. 

 aculeatum, but so far as I can find it is never found with that species, but 

 always either with P. Lonchitis or where that naturally grows, it passes 

 directly into that species both in Utah and Lambert Valley in the Mission 

 mountain.^, iwhere it is alpine. 



Cystopteris. Underwood in the sixth edition of his fern book takes up 



Filix to supersede Cystopteris because Adanson in 1763 published Filix, but 



the genus was improperly published, as no species were named. In addition 



Ludwig published a genus called Filix in 1757, but also did it improperly, as 



there were no species named. The name Filix was taken up by Gilib in 



1792 and F. bipinnata was published which is Athyrium or Asplenium Filix- 



foemina. Therefore the genus Filix has no standing and cannot supersede 



Cystopteris. 



' — Polystichum munitum (Kaulf.) Presl. MacDougal seems to have gotten 



Zllhis at the foot of MacDougal peak, though it is far out of range. 



— ' Botrychium ternatun var. Coulteri (Underwood Torr. Bull. 25 537 (1898) 



^ as species). Darby and Swan Lake. Tweedy was right in placing this as a 



variety of B. ternatum, as it intergrades freely.
