1923] SARGENT, NOTES ON NORTH AMERICAN TREES 103 



with this distinct and handsome shrub the name of General Rufus Putnam 

 who in 1788 laid out Marietta, the oldest town in Ohio. 



Crataegus illecebrosa (§ Coccineae), n. sp. 



Leaves ovate, acuminate at apex, abruptly cuneate or rounded at base, 

 divided usually only above the middle into short acuminate lobes and 



rply 



grow 



short soft hairs and pale and glabrous below, and at maturity thin, yellow- 

 green, glabrous, 6 cm. long and 5 cm. wide, with a thin midrib and primary 

 veins; petioles slender, slightly grooved, glabrous, 2.5-3 cm. in length; 

 leaves on vigorous leading shoots rounded at base, more deeply divided 

 into acuminate lobes, their petioles conspicuously glandular. Flowers 

 opening early in June, on slender glabrous pedicels, in mostly 10-12-flow- 

 ered globose corymbs; calyx-tube narrow-oboconic, glabrous, the lobes 

 separated by wide sinuses, slender, acuminate, irregularly glandular- 

 dentate or entire, glabrous on the outer surface, slightly villose on the 

 inner surface; stamens 20-25; anthers dark rose color or red; styles 3-5. 

 Fruit ripening late in October, obovoid, slightly mammillate at the narrow 

 base, crimson, marked by minute pale dots, 2 cm. long and 1.5 cm. wide, 

 the calyx little enlarged with a narrow deep cavity pointed in the bottom 

 and persistent spreading or erect lobes; flesh thick soft and succulent; 

 nutlets 3-5 rounded at the ends, narrower at base than at apex, rounded 

 and slightly grooved or prominently ridged on the back, 7-8 mm. long and 



3-5 mm. wide. 



An arborescent shrub about 4 m. high, with ascending branches and 



slender nearly straight branchlets dark green and marked by numerous 



pale lenticels when they first appear, becoming light red during their 



first season and ashy gray the following year and armed with occasional 



nearly straight slender spines 2.5-3 cm. in length. 



Ontario. Pastures in heavy clay soil about two miles northeast of Kings- 

 ton, J. Dunbar, Nos. 110 (type), and 102, October 19, 1911, and June, 6, 1912. 



This species appears to be most closely related to C. magniflora Sarg. 

 from northern Illinois, from which it differs in the soft not rigid hairs 

 on the upper surface of the young leaves which later in the season is not 

 scabrate like that of C. magniflora, in the less serrate calyx-lobes, and in 

 the softness of the flesh of the fruit which is unusually succulent in a 

 species of this group. 



Crataegus mansfieldensis (§ Rotundif oliae) , n. sp. 



Leaves ovate, acuminate, rounded or cuneate at base, laterally lobed 

 above the middle with short acuminate lobes, and finely doubly serrate 

 with short glands, covered above with short white hairs and villose below 

 along the midrib and veins, and at maturity thin, dark yellow-green, 

 smooth and glabrous on the upper surface, pale, scabrate and still slightly 

 villose on the lower surface aloncr the thin midrib and slender primary
