 with chestnut-brown or gray spines i.5-3 cm long : leaves cuneate, 

 2-4 cm long exclusive of the petioles, i-2 cm wide, or broader on 

 leading shoots, blunt or abruptly pointed, or sometimes shallowly 

 lobed at the apex, wedge-shaped at the base, the borders glandu- 

 lar and dentate near the apex ; they are pubescent or glabrate at 

 maturity, and when young are more or less pubescent on both 

 surfaces, especially along the midrib and prominent veins and in 

 their axils, bright green, firm to subcoriaceous in texture, fading

Cratcegus insidiosa was found in dry sandy upland woods at Ozark, Ala- 

 bama (type locality), and at other stations in the same general region of the same
