FLOWERING PLANTS AND FERNS OF ARIZONA 715 



9. Phlox woodhousei Torr. in A. Gray, Amer. Acad. Arts and Sci. 



Proc. 8: 256. 1870 (as P. woodhousii) . 



Phlox speciosa subsp. eu-speciosa var. woodhousei Brand. 



Pflanzenreich IV. 250: 73. ^ 1907. 

 Phlox woodhousei oculata A. Nels., Amer. Jour. Bot. IS: 433. 



1931. 



White Mountains (southern Apache and Navajo Counties to the 

 San Francisco Peaks (Coconino County), Prescott (Yavapai County . 

 Pinal Mountains (Gila County), and southwestern Cochise County. 

 3.500 to 7.500 feet, open woods on rocky slopes, flowering in spring 

 and autumn, type from near the present Fairview, Coconino County 

 Woodhouse in 1851). Almost endemic in Arizona, extending but a 

 short distance into Xew Mexico. 



This dwarf shrub is easily recognized by its thick oblong acutish or 

 obtusish leaves, and bright pink flowers with deeply notched corolla 

 lobes and short styles. 



10. Phlox nana Nutt., Acad. Xat. Sci. Phila. Jour, ser 2, 1: 153. 1848. 

 Rucker Valley. Cochise County, about 5.500 feet (Lemmon 415 . 



Western Texas, New Mexico, southeastern Arizona, and Chihuahua. 

 The species is represented in Arizona by subsp. glabella (A. Gray 

 Brand (P. triomdaia Thurb.), distinguished by eglandular pubescence. 

 The Lemmon collection was named by Brand P. nelsonii, but his 

 diagnostic character — lobes of the calyx 1 % times as long as the tube 

 —is too inconstant and trivial for nomenclatorial recognition. P. nana 

 is a herbaceous perennial, varying in habit from one season to another, 

 with purple to white corollas larger than in any other Phlox of Arizona. 



11. Phlox stansburyi (Torr.) Heller, Torrev Bot. Club Bui. 24: 47b. 



1S97. 



Phlox speciosa var. (?) stansburyi Torr.. U. S. and Mex. Bound. 

 Bot. 145. 1859. 



Northern Xavajo County to eastern Mohave County. 4.000 to 

 6.000 feet, dry soil, often with sagebrush, spring. Utah. Xevada, 

 Xew Mexico, northern Arizona, and eastern California. 



This species name has been applied to all sorts of dissimilar phloxes, 

 but the type material is characterized by having the corolla tube 20 

 to 25 mm. long, and there seems to be no reason for expanding the 

 definition of the species to cover the shorter-tubed P. cluten.a. P. 

 longifolidj P. amabilis, etc. 



12. Phlox longifolia Nutt., Acad. Xat. Sci. Phila. Jour. 7: 41. 1834. 

 Coconino, Mohave, and northern Yavapai Counties, 4.000 to 6,800 



feet, dry sandy or rocky slopes, spring. Wyoming to British Colum- 

 bia, south to Xew Mexico, Arizona, and California. 



Key to the subspecies 



1. Herbage eglandular; leave- short subsp. bumiljs. 



1. Herbage glandular in the inflorescence (2). 



2. Leaves (the larger ones) 50 to 70 ram. long, rather narrow 



and thin subsp. loxgipes. 



2. Leaves (none of them) more than 45 mm. long subsp. compacta. 



The sub-p. humilis (Dougl.) Wherry (P. humilis Dougl.) has been 



collected at Black Rock Spring, northern Mohave County ./■ 

 5098j). The subsp. longipes (Jones; Wherry (P. linearifolia var.
