GENTIAN FAMILY 



91 



white inside and greenish-dotted, sometimes pale blue or purple, 1 to 1^4 inches 

 long, commonly twice as long as the calyx, its lobes erect, ovate, acute, very short, 

 with a longitudinal slate-brown band outside; sinus-appendages broad, with 1 or 

 2 teeth. 



Alpine or subalpine meadows, 6600 to 12,000 feet : Sierra Nevada from Mt. 

 "Whitney to Lassen Peak; White Mts.; Siskiyou Co. North to southern Oregon. 

 July-Sept. 



Geog. note. — While it may occur as scattered individuals on the short-grass plateaus at high 

 altitudes, Gentiana newberryi often forms mat-like colonies 1 to 3 or 4 feet in diameter on dry 

 flats. There is some variation in corolla color, but it has not the significance implied in the 

 literature. Generally, perhaps always, the corolla has broad greenish or slate-brown bands out- 

 side. In the southern Sierra Nevada and commonly elsewhere the corolla is white ; in the northern 

 Sierra Nevada it is sometimes light blue ; on Mt. Eddy in the Salmon Mts. it may be purple. 



Concerning distribution of Gentiana newberryi in the north it is important to note that it 

 inhabits Lassen Peak {Brewer) and has been found twice on Mt. Eddy at the junction of the 

 Salmon Mts. and Trinity Mts. in the high North Coast Eanges. It thus falls into a special dis- 

 tributional category. That is to say, it belongs in the list of species which are found on the high 

 peaks of the northernmost Sierra Nevada and on the high Coast Eange peaks west of Mt. Shasta, 

 but not on Mt. Shasta itself.
