244 THE PLANT WOKLD. 



The writer longed to see the tops of other peaks three or four 

 thousand feet higher, but doubts very much whether there would 

 have followed any great additions to the excellent array of alpine 

 lichens that was spread at his feet at the lower level. 



One well acquainted with lichen species can collect them 

 very rapidly, but the second day on St. Piran In-ought to light 

 nearlv as much of interest as the first day on the somewhat 

 higher Mount Fairview. Both days revealed many lichens not 

 seen at the lower elevations reached at Glacier and not previously 

 known to the writer in the growing condition, and there is no 

 thought that the species were nearly all collected. Among those 

 of special interest, all found at the higher altitudes, are: Par- 

 melia stygia, in much more characteristic and more closely crus- 

 tose form than the specimens commonly seen from the White 

 Momitains ; Gryopliora cylindvicn and Ci/i'oplioni prohoscidea 

 alpicola; Buellia papiUata and the fruticose Lecidea pringlei, a 

 very rare Xortli American lichen; Parmelia lanata, which looks 

 enough like Epliehe pnhescens to cause the two to be sometimes 

 confused; Parmelia encausta alpicola and Lecidea airohrioiea; 

 the rare Tliamnolia veiinicularis ; Rhizocarpon alpicolum, occur- 

 ring with the common Bliizocarpon gcogvaphicum, and with its 

 beautiful greenish-yellow thallus, distinguishable from the lat- 

 ter only with the greatest difficulty; Cetraria nivalis and Cctra- 

 ria cucidlata, growing together and not easily distinguishable 

 when one sees them in the field for the first time; the two remark- 

 able and rare lichens, Cetraria arctica and Cetraria madrepon- 

 formis; and finally the scarcely less rare Cetraria aculeata al- 

 pina. 



The Canadian botanist, John Macoun, has, in A. O. Wheel- 

 er's remarkable book, ''The Selkirk Range," given a good view 

 of the natural history of the Selkirk country, and I am under 

 obligations to Mr. Macoun and the Canadian Government for a 

 copy of ]\rr. Wheeler's extremely interesting and instructive 

 book, for the privilege of rej^roducing one of the cuts used there- 

 in, and for a series of most excellent views and maps.
