too, are less lobed and the flowers with more glandular-serrate calyx- 

 lobes are larger in few r -flowered corymbs. 



Crataegus iterata (§ Silvicolae), nov. nom. 



Crataegus seclusa Sarg. in Bull. N. Y. State Mus. clxvii. 89, September 1913, 

 not Crataegus seclusa Sarg. in Trees and Shrubs, n. 239, August, 1913. 



By an oversight the name seclusa was unfortunately given by me in 



1913 to a Pruinosae species from southern Missouri, published in August, 

 and to a Silvicolae species from the Hemlock Lake region near Rochester, 

 N. Y., published in September. The new specific name, from itero, now 

 proposed for the New York species is in allusion to this repetition of names. 



Crataegus Putnamiana (§ Coccineae), n. sp. 



Leaves ovate, acuminate at apex, cordate or rounded at base, laterally 

 lobed with short acuminate lobes, and sharply doubly serrate to the base 

 with acuminate gland-tipped teeth; when they unfold tinged with red, 

 and covered above by short white caducous hairs, and at maturity thin, 

 glabrous, yellow-green on the upper surface, paler on the lower surface, 

 5-7 cm. long, and 4-6 cm. wide, and on vigorous leading shoots up to 

 8 cm. long and 7 cm. wide, with a slender prominent midrib and primary 

 veins; petioles slender, glandular, sparingly villose with short white hairs, 

 becoming glabrous, 2.5-4 cm. in length. Flowers opening from the 10th 

 to the middle of May, about 1.5 cm. in diameter, on slender pedicels in 

 5 or 6-flowered glabrous corymbs; calyx-tube narrow-obconic, glabrous, 

 the lobes narrow, long-acuminate, laciniately glandular-serrate, glabrous 

 on the outer surface, sparingly villose on the inner surface; stamens 16-20; 

 anthers dark red; styles 4 or 5. Fruit ripening early in October, on elon- 

 gated pedicels in drooping clusters, depressed-globose, slightly angled, 

 green, turning red, punctate, 1.5 cm. in diameter; calyx enlarged w r ith a 

 wide shallow cavity, broad in the bottom and spreading closely appressed 

 lobes; nutlets 4 or 5, rounded at apex, acute at base, prominently but 

 irregularly ridged on the back, 6 or 7 mm. long, 3 or 4 mm. wide, the 

 narrow brown hypostyle extending to the middle. 



A shrub up to 5 m. high, with erect stems covered with light gray bark, 

 and stout glabrous zigzag branchlets light chestnut-brown to olive green 

 when they first appear, chestnut-brown and lustrous in their second year, 

 and armed with stout straight spines 3-3.5 cm. in length 



Ohio. Washington County, common near Marietta, R. E. Horsey, No. 

 591 (type), September 27, 1916, May 20, 1917. 



Of the Coccineae only three species with glabrous corymbs and twenty 

 stamens and red, pink or rose-colored anthers have been described, C. 

 contigua Sarg. from Stockbridge, Vermont, C. magniflora Sarg. from 

 northern Illinois and Ganonoque, Ontario, and C. splendida Sarg. from 

 Sarnia, Ontario. From these species C. Putnamiana differs in its cordate 

 leaves w r ith villose petioles, and in its larger depressed-globose fruit, that 

 of the related species being short-oblong to obovoid. I have associated
