that it grows anywhere but on alkaline slopes where it is dry, and in the 

 juniper belt A. Wetherilli is given as growing on ^'plains and h'illsidea, 

 artemisia belt." It has never been seen but once and that along the 

 banks of the Grand river, east of Grand Junction, in the juniper belt. 

 A. allochroua is given as "plains and hillsides of the Covillea belt, upward 

 te the yellow pine belt." Its actual locus so far as I knov7 is never in 

 the covillea' belt, and never up to the yellow pine belt Then his ranrie is 

 far too great A. Eastwoodae he gives as "Valleyes of the artemisia 

 belt" It grows on sandstone ledges along the Grand river west of Grand 

 Junction, near Moab, in the juniper belt A. lutosus he aho never saw 

 the t>pe. He says it grows in barren scoil of the artemisia belt- It 

 grows only on sandstone ledges in western Colorado and not Utah. A. 

 Tejonesis he gives as growing in southern Nevada, when it is not knonn 

 to exist there. A. cermicus (pictus) he gives as growing on the plains 

 and rocky canons of the artemisia belt. Its real habitat is drifting ^arA 

 oi sandy places. A. triquetfus he gives as growing in canons, when it 

 grows on plains only. A. artipes he gives as growing in th^ yellow pai>e 

 and aspen belt Its real habitat is never in the aspen belt but in tlie 

 juniper belt up to the edge of the oak belt. It should be noted here that 

 the artemisia belt goes from the edge of the covillea to the asjDen. two 

 life zones, and includes the juniper and pinon belts as well, 

 and pinion belts belong to my Lower Temperate and Merrani"s Uprx^r 

 Sonoran. The upper part of the artemisia belt belongs to Merri^xfi 

 Transition, and to this belongs the yellow pine belt A. Whitneyi he 

 gives as from Nevada, but there is no evidence that it ever was found in 

 Nevada. A. Wardi he gives as growing in the aspen and spruce belt, 

 where it does not exist, as it grows in the oak and upper part of the 

 juniper belt A. Plomii he gives as growing in southern Utah, when it

 as canons and dry hillsides of the artemisia belt It grows only on loose 

 sandy ledges near Kanab, Utah, in the juniper belt A. Thompsonae he 

 gives as growing only in Utah on plains and hillsides, when it actually 

 glows in Nevada, and Arizona, in sandy places in the Covillea and 

 juniper belt, as well as southern Utah. A. Carolinianus he gives as 

 doubtfully in Utah. It does not grow there at all. The . only form 

 kjiown is the one he calls A. Mortoni. A. ursinus he gives as growing 

 in valleys of the artemisia belt in Utah, when it actually grows only in 



the Grand Canon, in the Covillea belt. A. calycosus

 Wyoming to New Mexico, Arizona and Utah, when it does not grow in 

 Wyoming, but occurs in south central Utah to northern Arizona and 

 Nevada. A. atratus he gives as a synonym for A. pinoriis Jone^, r\vlnch
