A shrub i-2 m tall, frequently growing in clumps or patches of 

 considerable area. Branches armed with chestnut-brown or gray- 

 spines i.5-4 cm long, the bark gray, tinged with brown, or the 

 growth of the season reddish-brown, marked with small pale lenti- 

 cels : leaves ovate, oval or broadly oval, 2-5. 5 cm long, exclusive 

 of the petiole, i.5-4 cm wide, acutely or bluntly pointed at the 

 apex, rounded or contracted at the base and prolonged into mar- 

 gined, glandular petioles 5 mm -2 cm long, the borders serrate and 

 incised, usually bearing at the base a few stalked glands ; they are 

 glabrous at maturity, but at the time of unfolding display some 

 slight pubescence on the upper surface, especially along the mid- 

 rib and bases of the largest veins, thin to firm in texture, yellow- 

 ish-green, fading with tones of yellow, orange and brown : flowers 

 i5-20 mm wide, expanding early in May and when the leaves are 

 almost or quite developed ; they are borne in simple, 2-5-flowered 

 corymbs which terminate short, leafy branchlets of the present 

 season's growth : pedicels and hypanthium glabrous : sepals 

 triangular lanceolate, 4-6 mm long, serrate and glandular : stamens 

 10, the anthers pale purple or nearly white : -fruit, which ripens 

 in late September, globose or subglobose, 9-1 3 mm in diameter, red 

 when ripe, the flesh firm : nutlets 3-5, 6~7 mm long, the lateral 

 surfaces nearly plane and the back grooved and ridged : hypostyle 

 about 3 mm long. 



Cratcegus communis grows on the limestone formation of the Cumberland 

 Mountains, near Cowan (type locality), Franklin county, Tennessee.
