FLOWERING PLANTS AND FERNS OF ARIZONA .).).) 



1. Leaves spatulate or obovate; petals none; fruit ovoid, ellipsoid, or somewhat 

 obovoid, often beaked with the persistent style, at maturity black without 

 bloom, less than 5 mm. in diameter (2). 

 2. Fruits nearly sessile; branchlets stout, very rigid, spiny throughout, rela- 

 tively short; leaf blades oblanceolate or obovate, 4 to 6 mm. wide, with 

 relatively slender and widely spaced, inconspicuous lateral veins. 



2. C. MEXICAN'.*. 

 2. Fruits distinctly pedicelled; branchlets slender, moderately rigid, spiny 

 toward the apex, relatively long; leaf blades spatulate, with broad con- 

 spicuous lateral veins, these occupying much of the surface (3). 

 3. Shrub usually not more than 2 m. high, very dense, the branches ascend- 

 ing, often crooked; leaves very numerous, crowded, 3 to 10 (commonly 

 about 5) mm. long including the petiole, 1 to 2 (rarely 3) mm. wide, 

 with veins occupying nearly the whole of the lower surface; bark of 

 the branchlets commonly dark gray; pedicels commonly shorter than 



the fruit 3. C. spathulata. 



3. Shrub up to 5 m. high, comparatively open, the branches divaricate, 

 nearly straight; leaves relatively few, not crowded, 7 to 12 mm. long, 

 2 to 5 mm. wide, with veins more widely spaced; bark of the branch- 

 lets light gray or brown; pedicels nearly as long as to longer than the 

 fruit 4. C. globosa. 



1. Condalia lycioides (A. Gray) Weberb. in Engler and Prantl, 



Pflanzenfam. 3 5 : 404. 1895. 



Zizy-phus lycioides A. Grav, Boston Jour. Nat. Hist. 6: 168.

Coconino and Mohave Counties to Greenlee, Cochise, Pima, and 

 Yuma Counties, 5,000 feet or lower (usually not above 3,000 feet), 

 common on dry plains, mesas, and slopes, often forming thickets, May 

 to September. Western Texas to southeastern California and northern 

 Mexico. 



Lotebush. The typical form, with glabrous or glabrate leaves, is 

 rare in Arizona, but has been collected near Douglas and San Ber- 

 nardino, Cochise County {Peebles 11694, 11703). The common form, 

 var. canescens (A. Gray) Trelease, has the leaves permanently canes- 

 cent. The plants reach a height of 2.5 m. (8 feet) but are usually 

 smaller. They are not or seldom browsed. Birds relish the insipid, 

 dark-blue fruits and find refuge in the impenetrable growth. The 

 Pima Indians treated sore eyes with a decoction of the roots, which 

 also have been used as a substitute for soap. 



2. Condalia mexicana Schlecht., Linnaea 15: 471. 1841. 



Cochise and Pima Counties, 3.000 to 4,500 feet, dry slopes and 

 canyons, usually with other large shrubs, July to September. South- 

 ern Arizona and Mexico. 



Mexican bluewood. The plants reach a height of 3 m. (10 feet). 



3. Condalia spathulata A. Gray, PL Wright. 1: 32. 1852. 

 Southwestern Gila County and eastern Pinal County to Cochise 



and Pima Counties, 3.500 to 4,500 feet, common on dry mesas and 

 "bajadas," July to September. Western Texas to south-central 

 Arizona and northeastern Mexico. 



Squawbush. Shrub up to 3 m. (10 feet high) but usually 1.5 to 2 

 m. The stones of the black fruits have a soapy taste and are only 

 slightly bitter.

 common on dry sandy plains and along washes, March. South-
