E. QvalifoUnm var. anaeriimm (Greene Pitt. 4 320.) 



This is a Western Nevada form with simple or compound 

 umbels having a sessile involucre in the center of the main umbel 

 and the secondary ones when present, the latter bearing only two 

 rays. The twisted petioles of which so much is made in the de- 

 scription are simply accidents to the type and are not found in 

 other specimens. This grows in the Middle Temperate life zone 

 along the Eastern side of the Sierras from Reno, Nevada north- 

 ward. The writer has duplicate type specimens. 



E. ochrocephalum var. angustum 



This connects the type with E. brevicaule var. pumiluin and 

 is close to E. spathulatum and E. pauciflorum, but cannot be a 

 hvbrid as the other species do not grow with it. It has the flowers, 

 peduncles and heads of E. ochrocephalum with an occasionally un- 

 equallv rayed umbel and the leaves of E. brevicaule. Deep Cr. 

 Mts., to the Oquirrh Mts., Utah, and .\ntelope Is., in Great Salt 

 Lake, in the Middle Temperate life zone, on rocks. Very variable. 



E. pauciflorum var. Fanguicense, 



Leaves short and very blunt, oblong-spatulate. little revolute. 

 not over 2 inches long; pedimcles filiform, 6-12 inches long; in- 

 volucres closely sessile, few. Panguitch, Utah. June 24. 1890. 

 Probably too close to the type. 



E. acaule var. longilobum (Jones Cont. 7 20.) 



Much resembling the type, but less densely matted; 

 leaves broadly-oblanccolate, on a petiole nearly as long as the 

 blade, margin inclined to be revolute, (obtuse; peduncles 1-2 inches 

 long, with 3-5 sessile involucres in a dense head : involucres parted 

 nearly to the base, the lobes 2 lines long, and with green tips; se- 

 pals obovate-oblong. rounded, yellow, with darker or green midrib, 

 often tinged with red. barely i Vi lines long. N'avajo Basin. 

 Lower Temperate life zone, in similar places; also intermediate 

 forms on the Great .Salt Lake Desert. This is probably the type of
