3. Anoda crenatiflora Ortega, Hort. Matr. Dec. 96. 1798. 

 Tumacacori Mission, Santa Cruz County, about 3,000 feet, in 



thickets {Harrison 8146), August and September. Southern Arizona 

 and Mexico. 



4. Anoda reticulata S. Wats., Amer. Acad. Arts and Sci. Proc. 17: 



368. 1882. 

 Santa Catalina Mountains, Pima County (Pringle in 1881, the type 

 collection), Sycamore Canyon near Ruby, Santa Cruz County 

 (Kearney and Peebles 14453). Known only from southern Arizona. 



5. Anoda abutiloides A. Grav, Amer. Acad. Arts and Sci. Proc. 22: 



300. 1887. 



Pima County, Santa Catalina Mountains (Pringle in 1882, the type- 

 collection), Baboquivari Mountains (Peebles et al. 387, etc.), 3,500 to 

 5,000 feet, rich soil in canyons, May to October. Apparently known 

 only from southern Arizona but doubtless also in Sonora. 



This plant bears a marked resemblance to Abutilon sonorae in its 

 large, deeply cordate, long-pointed, velvety-pubescent leaf blades. 

 In structure of the carpels it forms a link with the genus Sida, the 

 lateral walls, although fragile, being more persistent than in any other 

 species of Anoda.

299. 1886. 



Cochise County, at Paradise, Chiricahua Mountains, on limestone,

10. HIBISCUS. Rosemallow 



Plants perennial, often shrubby; leaf blades merely crenate or 

 dentate, or pedately cleft; flowers axillary, solitary, the petals 2 cm. 

 long or longer; involucel usually present; fruit a loculicidal capsule, 

 the carpels 5; seeds several in each carpel, long-hairy. 



Key to the species 



1. Petals lavender; bractlets less than half as long as the calyx, often fugacious; 

 stems densely grayish canescent or tomentose with short, stellate hairs; 



plant suffrutescent or shrubby 1. H. denudatus. 



1. Petals yellow, with a large red basal spot; bractlets nearly equaling to longer 



than the calyx, persistent; stems strigose or hispid with long, simple or 



forked hairs (2). 



2. Stems distinctly woody above the caudex, homogeneously strigose with 



forked hairs; pedicels usually disarticulating at maturity of the fruit; 



seeds completely covered with long hairs 2. H. coulteri. 



2. Stems scarcely woody above the caudex, finely pubescent in 1 or 2 lines, 

 also hispid with long, simple or forked hairs; pedicels not disarticulating; 

 seeds naked or nearly so in the center 3. H. biseptus.
