222 ROSACEA. Crat^gus. 



A shrub or small tree 10-20 feet high ; the spines 1-2 inches long, usually a little 

 curved. Leaves about 2 inches long, cut into from 5 to 9 shallow lobes, which again are 

 irregularly serrate, for the most part abruptly narrowed and acute at the base, but often obtuse, 

 truncate or cordate, especially on the sterile branches, smooth, or very sparingly pubescent 

 with short appressed hairs ; the petiole often a little glandular. Flowers white, of a powerful, 

 and, to most persons, disagreeable odor, as they are in several other species of the genus. 

 Segments of the calyx lanceolate, denticulate and usually (as also the bracts) glandular on the 

 margin. Stamens about 20. Fruit nearly half an inch in diameter, red or reddish-purple 

 when ripe, eatable, but the pulp thin. 



Borders of woods, in thickets, and along streams of water. Fl. May. Fr. September. 



4. Crat^gus tomentosa, Linn. Black Thorn.

 almost smooth ; peduncles and calyx villous-tomentose ; segments of the calyx pectinately
