FLOWERING PLANTS AND FERNS OF ARIZONA 1035 



Gila, Cochise, and Pima Counties; C. flavus, Gila, Cochise, and Pima 

 Counties; C. mutisii, Graham, Santa Cruz, and Pima Counties. 



Scirpus californicus (C. A. Mey.) Steud., Nov. ed. 2, 2: 538. 1841. 



As this species occurs in California and New Mexico, it is to be 

 looked for in Arizona. It somewhat resembles S. validus and *S'. 

 acutus (see p. 162), but the stem is triangular, at least toward the 

 apex, and the perianth bristles are plumose. 



Salix geyeriana Anderss., Amer. Acad. Arts and Sci. Proc. 4: 63. 1858. 

 This willow occurs in Apache, Navajo, Coconino, and Yavapai 

 Counties. It has distinctly petioled leaves with narrowly lanceolate 

 or oblanceolate, entire or nearly entire blades, these sparsely short- 

 pilose above and glaucous beneath. The pistillate catkins are short 

 and broad, and the capsules are pubescent. It is readily distinguished 

 from S. bebbiana Sarg. (see p. 219) by its much narrower leaf blades. 



Paronychia jamesii Torr. and Gray, Fl. N. Amer. 1: 171. 1838. 



E. L. Core (The North American species of Paronychia. Amer. 

 Midland Nat. 26: 393.^ 1941) refers the Eastwood and Howell collec- 

 tion (see p. 312) to P. jamesii and cites also a collection by Lemmon in 

 the Chiricahua Mountains. P. depressa Nutt. should therefore be 

 excluded from the flora of Arizona. 



Draba spectabilis Greene, Pittonia 4: 19. 1899. 



This has been collected in the Lukachukai Mountains, northern 

 Apache County (Peebles 14388). The collection in question belongs 

 to var. typica C. L. Hitchc. This species has the pods flat or nearly so 

 and mostly shorter than the pedicels, whereas in the other perennial, 

 leafy -stemmed, yellow-flowered species of Arizona, D. aurea, D. pe- 

 trophila, D. helleriana (see pp. 361, 362), the pods are usually more or 

 less twisted and longer than the pedicels. 



Prosopis (see p. 420). Benson 23 refers the Arizona specimens 

 which the writers regarded as belonging to Prosopis juliflora var. 

 glandulosa (Torr.) Cockerell to a new variety, var. torreyana Benson, 

 and restricts the area of var. glandulosa to Kansas, Louisiana, Texas, 

 and eastern New Mexico. He also considers the name Prosopis 

 pubescens Benth. to be the proper designation of the Fremont screw- 

 bean, rather than P. odorata Torr. and Frem. 



Phaseolus wrightii A. Gray (see p. 505). The var. gray anus com- 

 monly has a very short, relatively stout, persistent style, but in some 

 of the Arizona specimens the style is as long and slender as in the type 

 collection of P. wrighHi A. Gray. 



Strophostyles. An unidentified and perhaps undescribed species of 

 this genus has been collected between Nogales and Ruby, Santa Cruz 

 County (Kearney and Peebles 14901). It has narrowly lanceolate, 

 entire, thickish, prominently reticulate-veined leaflets. The genus 

 differs from Phaseolus (see p. 503) in having the keel petals strongly 

 incurved but not curled or coiled. 



Echinocactus. A species of Echinocactus was discovered in L939 

 in the vicinity of Holbrook, Navajo County. Reference to this dis- 

 covery is omitted from the text (see pp. 599-603) for tin 4 reason thai
