A tree 3-4 m. high, with a trunk 8- ro cm. in diameter, and stout

Bissell (no. 72 type), September 1903, May 1904. 
Well distinguished by the very broad laciniate calyx-lobes enlarged 
and erect on the beautiful dark lustrous fruit. 
Crataegus spatiosa, n. sp. Leaves ovate, acute or acuminate, 
rounded or abruptly concave at the broad entire often unsymmetrical 
base, sharply doubly serrate above, with straight glandular teeth, 
and divided into 5 or 6 pairs of short broad acuminate lateral lobes, 
more than half grown when the flowers open during the last week of 
May and then thin, dark green, shining and slightly roughened above 
by short whitish hairs and paler and sparingly villose below along ` 
the midribs and veins, with short hairs mostly persistent throughout 
the season, and at maturity thin but firm to subcoriaceous, smooth, 
dark green and lustrous on the upper and pale yellow-green or 
whitish on the lower surface, 6-8 cm. long, 5.5-7 cm. wide; petioles 
stout, narrowly wing-margined at the apex, glabrous, glandular, with 
small stipitate red persistent glands, 2.5-3 cm. in length; stipules 
linear, glandular-serrate, fading rose color, caducous; leaves on vig- 
orous shoots broadly ovate, gradually narrowed and concave-cuneate 
at the base, more coarsely serrate, often deeply divided into broad 
acuminate lobes, 7-8 cm. long and 6-7 cm. wide. Flowers cup- 
shaped, 2-2.3 cm. in diameter, on short slender glabrous pedicels, in 
compact usually 5—9-flowered corymbs, with linear-lanceolate bracts 
and bractlets, fading brown and generally deciduous before the flow- 
ers open; calyx-tube narrowly obconic, glabrous, the lobes slender, 
acuminate, obscurely glandular mostly near the middle, reflexed after 
anthesis; stamens ro; anthers pale cream-color; styles 3, or rarely 
4, surrounded at the base by a narrow ring of pale tomentum. Fruit 
ripening early in October, on slender erect pedicels, in few-fruited 
clusters, oval to globose or rarely depressed globose, concave at the
