FONTINALIS. 83 



as when dry almost to appear setaceous. They are plane, or 

 very slightly concave, not carinated, and are imbricated on 

 all sides of the stem. The fruit, though smaller, agrees in 

 every other particular with that of F. antipyretica. 



Notwithstanding that so many botanists have taken up 

 this species without even expressing a doubt as to its title 

 to rank as such, we cannot help offering it as our opinion 

 that more perfect individuals than we have had the good 

 fortune to see, will prove to have some carinated and con* 

 duplicate leaves, and thus bring them to the common alpine 

 state of F. antipyretica. Of this we are certain, that all 

 our specimens of F. sqitamosa (as we had fondly hoped 

 them to be), which we had gathered with so much eager- 

 ness in the alpine rills of the most elevated mountains of 

 England and Scotland, have turned out upon a more accu- 

 rate investigation to be the common species.

With this species we are likewise but little acquainted, 

 having only seen it in Mr. Turner's rich Herbarium, and, like 

 the last described, received from our great cryptogamist 

 Mr. Dickson. In the specimens there preserved the stems 

 are from two to three inches long, but evidently broken, so 

 that they can give no just idea of the length, which Dille- 

 nius represents as a span or more, branched. The leaves 

 are subsecund, especially towards the extremity of the 

 branches, of a brownish green colour, long-subulate, con- 

 cave or a little carinate, furnished with a strong nerve. Pe- 

 richaetiurn half an inch in length, lateral, arising from the 

 lower part of the stem or branches ; its leaves very long and 

 sheathing. No fructification in a more advanced state has 

 been found on Mr. Dickson's Scotch specimens : but Dil- 

 lenius, whose Pennsylvanian specimens, above referred to, 

 are considered to be the same, thus describes the perichsetia 

 and capsules : " e foliorum alis, prsesertim qua rami egre- 

 diuntur, calyces enascuntur longi, styli instar porrecti, ab
