thinly covered when they first appear with matted pale hairs, soon glabrous, 

 reddish brown during their first season, becoming ashy gray and unarmed 

 or occasionally furnished with short slender straight spines sometimes 

 becoming compound on main stems.

This species, which resembles C. poliophylla Sargent of the same general 

 region in the shape of the leaves and in the size of the flowers, differs from 

 it in the nearly entire absence of pubescence which is so conspicuous on 

 C poliophylla, and in the pink not yellow anthers 



Crataegus sutherlandensis (§ Virides), n. sp. 



Leaves ovate, acute at apex, gradually or abruptly narrowed and 

 concave-cuneate at base, coarsely doubly serrate with straight or incurved 

 acuminate teeth; coated with pale pubescence when 'they unfold, soon 

 glabrous, fully grown when the flowers open, and at maturity thin, dull 

 yellow-green, slightly scabrate on the upper surface, 3-4 cm. long and 

 2-2.5 cm. wide, with a thin midrib and slender primary veins slightly 

 raised on the upper surface; petioles slender, slightly wing-margined, 

 sparingly villose early in the season, soon glabrous, 8-15 mm. in length; 

 leaves on vigorous shoots rounded at base, often irregularly divided into 

 short wide lateral lobes, 4-5 cm. long and broad. Flowers opening late 

 in March, 2 cm. in diameter, on long slender glabrous pedicels, in lax 

 usually 7-10-flowered corymbs; calyx-tube narrow-obconic, glabrous, the 

 lobes slender, acuminate, often laciniately divided near the base into 

 glandular teeth, glabrous on the outer surface, villose-pubescent on the 

 inner surface; stamens 20; anthers faintly tinged with pink; styles 5. 

 Fruit ripening the end of September, subglobose, often truncate at base, 

 orange-red, 7-8 mm. in diameter, the calyx prominent, with erect and 

 spreading lobes and a narrow deep cavity; nutlets 5, rounded at apex, 

 acute at base, obscurely grooved on the back, 5-6 mm. long, 3-4 mm. 



wide, the broad conspicuous hypostyle extending nearly to the base. 



A slender tree 4 or 5 m. high, with a trunk covered with dark gray 

 bark separating freely into long thin oblong flakes disclosing the red inner 

 bark, erect and spreading branches, their bark smooth and gray, and 

 slender slightly zigzag branchlets orange-green and sparingly pilose above 

 when they first appear, soon red-brown and glabrous, and ashy gray in 

 their second season, often unarmed or furnished with occasional straight 

 slender spines up to 5 cm. in length.
