FLOWERING PLANTS AND FERNS OF ARIZONA 309 



Catalina Mountains (Pima County), 8,000 to 12,000 feet, commonly 

 in coniferous forests, May to September. New Mexico, Arizona, 

 and northern Mexico. 



The distribution in Arizona, as given above, is that of the typical 

 form, a compact plant with low matted stems seldom more than 10 

 cm. long and small, oblong-lanceolate leaves. Two other forms that 

 occur in Arizona, both of them less compact plants with taller stems 

 and longer narrower leaves, are: (1) Var. dnerascens Robinson, 

 ranging from the Lukachukai Mountains (Apache County) and the 

 Kaibab Plateau (Coconino County), to the mountains of Cochise 

 and Pima Counties, 7,000 to 9,000 feet; (2) var. mearnsii (Woot. 

 and Standi.) Kearney and Peebles (A. mearnsii Woot. and Standi.), 

 in the mountains of Graham, Cochise, Santa Cruz, and Pima Counties, 

 4.000 to 9.000 feet. The stiff er stems, more erect leaves and fine 

 grayish pubescence distinguish var. dnerascens from var. mtarnsii, 

 but there is intergradation among all forms of this species. 



6. Arenaria capillaris Poir. in Lam., Encycl. 6: 380. 1804. 

 Coconino and Yavapai Counties, also Superstition Mountains 



(Pinal County), 5,000 to 8,000 feet, May and June. Alberta and 

 British Columbia to Arizona and California; Asia. 



The American plant is A. formosa Fisch., considered by Rydberg 

 to be specifically distinct from the Asiatic A. capillaris. 



7. Arenaria fendleri A. Grav, Amer. Acad. Arts and Sci. Mem. ser. 



2, 4: 13. 1849. 



Apache County to Mohave County, 4,000 to 12.000 feet. April to 

 September. Wyoming to Xew Mexico and Arizona. 



A common plant of the yellow pine forests, becoming very depau- 

 perate near the summit of the San Francisco Peaks. 



In a recently published paper (Maguire, Bassett. Great Basin plants. III. 

 Caryophyllaceae. Madrono 6: 22-27. 1941), a form of .4. fendleri with rela- 

 tively short leaves and long petals, subsp. brevijolia Maguire, is recorded as 

 occurring in the Kaibab National Forest; and .4. aberrans M. E. Jones, related 

 to ^4. capillaris but having very large, urn-shaped capsules, is reported from 

 Grand Canyon National Park, and from Mount Dellenbaugh, northern Mohave 

 County, where the type is stated to have been collected. 



8. Arenaria eastwoodiaeRydb., Torrey Bot. Club Bui. 31: 406. 1904. 

 Apache County to Coconino Cotmty, 5,000 to 7.000 feet, sandy soil 



on plains and mesas, tending to make small hummocks, June to 

 September. Colorado, Utah, Xew Mexico, and northern Arizona. 

 The typical glabrous form is less common in Arizona than the 

 glandular-puberulent var. adenophora Kearney and Peebles. The 

 Hopi Indians are reported to use the plant as an emetic. 



9. Arenaria aculeata S. Wats, in King, Geol. Expl. 40th Par. 5: 40. 



1871. 

 Navajo County to Mohave and Yavapai Comities, 4,000 to 9,000 

 feet, May to September. Idaho and Oregon to Xew Mexico, Arizona, 

 and California. 



10. Arenaria macradenia S. Wats., Amer. Acad. Arts and Sci. Proc. 



17: 367. 1882. 



San Francisco Peaks (Lemmon in 1884), Beaver Dam Creek. 

 Mohave County [Goodding 771). Utah and Arizona to California. 



These Arizona specimens are referred somewhat doubtfully to .1. 

 macradenia.
