COMPOSITE 



Brickellia calif ornica Gray. Frequent in dry sunny ground throughout the Tran- 

 sition Zone. Reaching 8000 ft. alt. (Nos. 1536, 1642.) 



Brickellia ynicrophylla Gray. Frequent in gravelly ground in San Antonio Canon 

 and in North Fork Lytle Creek.. A Lower Transition plant which occa- 

 sionally descends into the Upper Chaparral Belt as at Camp Baldy, alt. 4500 

 ft. The maximum altitude noted was 6500 ft. Det. B. L. Robinson. (No. 

 1643.) 



Chrysopsis villosa (Pursh) Nutt. var. fastigiata (Greene) Hall. Common in dry 

 ground in the Lower Transition Zone. (No. 1701.) 



Solidago confinis Gray. Wet ground at the Native Son Mine, alt. 5000 ft. Lower 

 Transition Zone. (No. 1674.) 



Solidago californica Nutt. Common under the pines in slightly moist places. 

 Transition and Upper Sonoran Zones. (Nos. 1697, 1710.) 



Ericameria cuneata (Gray) McClatchie var. spathulata (Gray) Hall. Seen in the 

 pine belt at three stations. At 6500 ft. alt. at San Antonio Cafion Falls, at 

 6750 ft. alt. in Middle Fork Lytle Creek and at 7000 ft. alt. on the west end 

 of Ontario Peak. Very common on rock ledges in the Upper Chaparral Belt.

Chrysothamnus nauseosus (Pall.) Britt. vars. This genus is in the process of 

 revision and so no attempts will be made to give varietal determinations. 

 The common form of this species is abundant in dry sunny ground in the 

 Transition Zone on the north side of the mountain. On the south side 

 shrubs of this species are infrequent and are usually found in the washes at 

 the lower edge of the pine belt. Another form of nauseosus represented by 

 my No. 1652 was found growing with the last form on a dry sunny ridge-crest 

 in the Transition Zone, alt. 8000 ft., on Pine Mt. Ridge. It is distinguished 

 from the last form by its long, slender erect stems that are abundantly to- 

 mentose and by the very loose inflorescence. (Nos. 1652, 1653, 1706.) 



Chrysothamnus vicidiflorus (Hook.) Nutt. var. tortifolius (Gray) Hall. "Mt. San 

 Antonio" ace. Abrams (Fl. Los. Ang. 366, 1917). 



Corethrogyne filaginijolia (H. & A.) Nutt var. pinetorum Johnston. Frequent in 

 dry ground under the pines in the Lower Transition Zone. Frequent on open 

 slopes in the Upper Chaparral Belt especially in the region of Sunset Peak. 

 (No. 16-14.)
