a favorite fuel of local residents. Standley 3 states that the Gosiute Indians, 

 of Utah, employed the wood of this plant in making their bows. The mature 

 leaves of curlleaf mountain-mahogany are hairless and shiny on the upper 

 surface and are covered with a dense felt of hairs on the lower surface. They 

 vary in length from about one-half to 1% inches, and in width from three- 

 sixteenths to seven-sixteenths of an inch, but are usually small (one-sixteenth 

 of an inch wide and one-half of an inch long) in scrub specimens. The upper 

 surface appears to be grooved along the middle because of the thick midrib, 

 which stands out prominently on the lower surface. The nearly triangular 

 bracts (stipules) at the base of the leafstalks are very small and soon fall off 

 (deciduous). The flowering period is from May to July. 



Arizona mountain-mahogany (C. arizo'nicus) , a spiny-twigged shrub which 

 occurs in canyons and on mountain sides of the sagebrush and pifion belts from 

 central Utah and Nevada to Arizona, is closely related to curlleaf mountain- 

 mahogany. It does not attain tree size, has ashy-colored bark, and the leaves, 

 which are about half as long as those of C. ledifolius, are so strongly rolled 

 under at the margins as to appear narrowly linear. Although this species is, 

 on the whole, considered inferior from the forage standpoint, it ranks relatively 

 high in some localities as winter feed for game. Littleleaf mountain-mahogany 

 (C. intrica'tus), a similar species, extends into southern California but other- 

 wise has a like range and economic status.
