REPORT OF THE STATE BOTANIST I905 73 



about 1.5 cm in diameter. In later seasons, however, Professor 

 Peck has found them somewhat smaller, and, except in the color of 

 the anthers and in the size of the fruit and its larger calyx lobes, 

 I can find nothing by which to distinguish the Albany plant from 

 Crataegus gemmosa. 



Anthers pale yellow 

 Crataegus halliana n. sp. Sarg. 



Leaves oblong-obovate to oval, acute or acuminate, gradually 

 narrowed and concave cuneate at the slender entire base, finely 

 doubly serrate above, with minute glandular teeth, and very slightly 

 divided above the middle into small acute lobes, about half grown 

 when the flowers open the ist of June and then thin, yellow green, 

 scabrate and slightly hairy above along the midribs and pale and 

 sparingly villose, with short persistent hairs below along the midribs 

 and veins, at maturity subcoriaceous, conspicuously reticulate- 

 venulose, dark green, smooth and lustrous on the upper and pale 

 on the lower surface, 5-6 cm long, 3.5-4 cm wide, with thin yellow 

 midribs and veins deeply impressed on the upper side; petioles 

 slender, narrowly wing-margined to below the middle, grooved and 

 villose while young along the upper side, soon glabrous, tinged with 

 red in the autumn, 1.5-2 cm in length; leaves on vigorous shoots 

 sometimes more deeply lobed, 6-7 cm long and 4-5 cm wide, with 

 stout broadly winged petioles and slender falcate acuminate rose- , 

 colored caducous stipules. Flowers 1.2-1.3 cm in diameter, on long 

 slender villose pedicels, in broad 8 to i6-flowered crowded corymbs, 

 with long several-flowered peduncles from the axils of the two upper 

 leaves; calyx tube narrowly obconic, villose at the base, glabrous 

 above, the lobes slender, acuminate, laciniately glandular-serrate, 

 glabrous on the outer, villose on the inner surface, reflexed after 

 anthesis; stamens 20; filaments short; anthers pale yellow; 

 styles two or three. Fruit very abundant, ripening early in October, 

 on long drooping reddish pedicels, in wide many-fruited corymbs, 

 subglobose, crimson, lustrous, marked by large dark dots, 1-1.2 cm 

 in diameter; calyx little enlarged, with a deep narrow cavity, and 

 spreading closely appressed glandular-serrate lobes coated on the 

 upper side with matted pale hairs; flesh thick, tinged with red, soft 

 and very succulent; nutlets two or three, gradually narrowed and 

 rounded at the ends, ridged on the back, with a broad grooved ridge, 

 penetrated on the inner faces by large deep cavities, about 7 mm 

 long and 4 mm wide.
