aud falling- in October. Flowers, appearing- the last week in 

 May in small loose slightly compound glabrous clusters, are 

 about 2U mm wide; stamens 10, seldom 5-10, anthers rose- 

 purple. Fruit, borne in small nearly simple clusters on rather 

 long- spreading- pedicels and ripening- in October, is slightly 

 oblong, 8-10 mm long and 7-9 mm thick, flattened at the ends, 

 dark red or crimson, seldom with orange spots at apex, capped 

 by the closely sessile appressed lanceolate entire lobes, which 

 are often appressed pubescent above; flesh firm, sweet, juicy, 

 pale yellow; seed 4-5, small, 5-6 mm long, sometimes grooved 

 on the back.

Crataegus sequax. Arborescent, 4 m in height, with a 

 round crown of ascending- flexuous branches; the purplish- 

 brown usually glabrous twigs armed with many 1-5 cm-long 

 rather stout thorns. Leaves soon nearly or quite glabrous, 

 firm, deltoid, broadly ovate or ovate, 3-6 cm long, 2.7-5.5 cm 

 wide, rounded or truncate at the base, usually 3-4 short acute 

 lobes, sharply serrate, petiole slender, rarely puberulent. 

 Flowers, appearing the second week in May in small compact 

 slightly compound cymes, are about 20 mm wide; stamens 

 5-10, frequently 8, anthers purple. Fruit, ripening the last 

 of September and falling with and after the leaves and borne 

 in short compact usually simple clusters, is globose or sub- 

 globose 12-15 mm long and thick, dark red or crimson, often 

 blotched with green or russet at the apex, the narrow suben- 

 tire lobes spreading, reflexed or ascending-.

Crataegus vittata. Arborescent, 4-5 m high, with rather 

 stout red-brown glabrous twigs sparingly armed with 5-6 

 cm-long stout thorns. Leaves ample, thin, firm, soon glab- 

 rous, broadly oval, the blades 5-7 cm long, 5-6 cm wide, 

 rounded or truncate at the broad base, abruptly acute at apex, 

 3-4 pairs of broad short lobes; petioles very slender, 2.5-4
