This is one of the prevailing species on the hillsides north of 

 Albany. The flowers have a strong potash odor. It is closely re- 

 lated to C. acutiloba Sarg. with which it was formerly 

 united, but its flowers are smaller and its nutlets more numerous, 



COCCINEAE

Crataegus gravesii Sarg. 

 Graves thorn 

 Rhodora, 5 : 159 



Shrub or small tree with widely spreading or ascending 

 branches ; leaves ovate, obovate, elliptic or subrotund, thin, acute 

 or rounded at the apex, rounded or cuneate at the entire base, une- 

 qually serrate with rather broad blunt teeth, with 3-4 short, broad, 

 acute or rather blunt lobes each side, at flowering time 

 pale green, glabrous or with a few scattered hairs above, when 

 mature firm, glabrous, dark green and shining above, paler below, 

 1-2 inches long and nearly or quite as broad, petioles slender, 4-12 

 lines long, slightly margined at the apex, sometimes slightly 

 villose and glandular when young; flowers 5-12 in a cluster, on 

 slender, short, glabrous or slightly hairy peduncles, calyx glabrous,, 

 its lobes narrow, elongated, minutely glandular, stamens 4-8, 

 occasionally 10, anthers pale yellow or whitish ; fruit globose or 

 depressed globose, erect, pale red or orange red when ripe, 

 crowned by the short erect or spreading calyx lobes, nutlets 2-3. 



Clayey soil. Albany, North Greenbush and Westport. Flow- 

 ers late in May or early in June, fruit ripens late in September. 

 Closely related to C. coccinea rotundifolia, from 

 which it may be separated by its thinner leaves, mostly fewer 

 stamens, paler fruit and fewer nutlets. Our examples are shrubs 

 more glabrous than the type. The young unfolding leaves are 

 sometimes tinged with brownish red.
