FLOWERING PLANTS AND FERNS OF ARIZONA 71 



2. Ephedra torreyana S. Wats., Amer. Acad. Arts and Sci. Proc. 14: 



299. 1S79. 

 Apache County to Mohave County, mostly 4,000 to 6,000 feet. 

 Southwestern Colorado to Nevada, south to western Texas, Arizona, 

 and Chihuahua. 



3. Ephedra viridis Coville, Contrib. U. S. Natl. Herbarium 4: 220. 



1893. 

 Navajo, Coconino, Mohave, and Yavapai Counties, 3,000 to 7,000 

 feet. Southwestern Colorado, Utah, Nevada, Arizona, and Cali- 

 fornia. 



4. Ephedra cutleri Peebles, Wash. Acad. Sci. Jour. 30: 473. 1940. 



Ephedra coryi Reed var. viscida Cutler, Mo. Bot. Gard. Ann. 

 26: 413. 1939. 



Apache, Navajo, Coconino, and Yavapai Counties, mostly 5,000 to 

 6,000 feet, type from west of Rock Point, Apache County {Cutler 2209) . 

 Southwestern Colorado, southeastern Utah, northeastern New 

 Mexico, and northwestern Arizona. 



Similar in many respects to E. viridis, but distinguished by 

 the well-developed peduncles and often viscid stems. This Ephedra 

 is very common on the Navajo Indian Reservation, often growing 

 so thickly on sandy plains as to resemble a luxuriant growth of grass. 

 Ephedra arenieola Cutler is the name for a presumable hybrid between 

 E. torreyana and E. cutleri found near Dinnehotso, Apache Countv 

 (Cutler 2217 and 2221). 



5. Ephedra nevadensis S. Wats., Amer. Acad. Arts and Sci. Proc. 14: 



298. 1879. 

 Kingman, Mohave County (Eastwood 18007). Oregon, Utah, 

 Arizona, and California. 



6. Ephedra fasciculata A. Nels., Amer. Jour. Bot. 21: 573. 1934. 

 Mohave, Graham, Gila, Pinal, Maricopa, and Yuma Counties, 



desert regions, up to about 4,000 feet, type from Phoenix (Maricopa 

 County). Arizona and California. 



Although E. fasciculata was described originally from sterile 

 branches, Cutler describes the seeds as 8 to 13 mm. long. E. clokeyi 

 Cutler, with seeds only 5 to 8 mm. long, is very similar. This, a 

 more common form in Arizona than typical E. fasciculata, ranges 

 into Utah, Nevada, and California. 



E. calif ornica S. Wats, and E. aspera Engelm. are also stated by Cutler to occur 

 in Arizona, but examination of the Arizona specimens cited by him indicates 

 that they do not belong to the species in question. 



3. TYPHACEAE. Cattail family 



1. TYPHA. Cattail 



Semiaquatic perennial herbs; flowering stems from creeping root- 

 stocks, tall, terete, not jointed; leaves long, flat, equitant; flowers 

 monoecious, very numerous in a dense eylindrie spike, the st animate 

 ones above; perianth reduced to bristles; ovary stipitate, 1- or 2-celled.
