NEW Oli NOTEWORTHY SPECIES. 10 



by melting snows about Crater Lake on Mt. Kainier ; 20 

 August, 1889, in leaf and fruit only. The plant is so common 

 and plentiful on the northward slope of the mountain above 

 named, that I can hardly think it does not occur on other 

 snowy mountains of AYashingtou and Oregon, and that others 

 may have collected it. I have even a suspicion that some of 

 the ''P. pahnafa'' from the farther northwestern stations 

 will be of the present very different species. TJie real P. 

 palmcda is a woodland plant, the stems of which grow singly, 

 or very few together. P. nivalis belongs exclusively to sub- 

 alpine heights, where, along the margins of snow-banks and 

 icy rivulets it forms a border of vegetation which, although 

 low, is so compact that the traveler avoids it. P. pahvafa is 

 very common in the woods that skirt the remoter bases of 

 ilainier ; and a long interval of distance as well as of altitude 

 separates between it and the habitat of this which I am com- 

 pelled to regard as hitlierto undescribed. There is no species 

 of either the New World or the Old to which is attributed a 

 foliage so much divided and subdivided as that here described. 

 The flowers are, of course, unknowTi. The station is probably 

 inaccessible to travelers until after its flowering time is past 

 In August the fruit had evidently long since matured ; only 

 the dead stalks wath their vacant involucres were remaining. 

 After the low sedges and grasses, the most common associates 

 of this Pefasitcs were Spiroea pedinaia, Leptarrliena puro- 

 Icefolia ami Scorzonella horealis} 



"^ Senecio Franciscanijs. Perennial, low, more or less crespi- 

 tose from running rootstocks : flowering stem 2 or 3 inches 

 high, very leafy at base ; lower leaves rounded and toothed, 

 the upper lyrate-pinnatifid, all coriaceousj none more than an 

 inch long, including the petiole : heads 1 to 5, large, sub- 

 sessile, with few short but broad rays.

 no room for doubt that it belongs to Nuttall's genus Scorzonella
