bear a few weak hairs on both surfaces along the midrib and in 

 the axils of the veins beneath, dull to bright green, thin to firm 

 in texture, fading with tones of yellow, brown and orange : pet- 

 ioles 5-1 5 mm long, margined, glandular: flowers i6-i8 mm wide, 

 opening about the 10th of April and when the leaves are two- 

 thirds grown ; they are disposed in simple, 3-5-nowered corymbs 

 which terminate short, leafy branchlets : pedicels and hypanthium 

 glabrous : sepals 3-4 mm long, entire or glandular-serrate, reflexed 

 after anthesis : stamens 20, the anthers light yellow or nearly 

 white : fruit, which ripens and falls in September, globose, 

 7-1 o mm in diameter, at maturity yellow or orange-red, the cheeks 

 often bright red : nutlets 3-5, 5-6 mm long, the lateral surfaces 

 nearly plane : hypostyle about 4 mm long. 



Cratcegus calva grows in woods and on ridges at Ozark, Alabama (type 

 locality). 



The original specimens, consisting of flowers {/I^ny) and fruit (H3004) 

 from the same shrub, are preserved in the Biltmore Herbarium. 



Crataegus tristis n. sp. 



A large shrub or small tree 3-7™ tall, sometimes with a trunk 

 2 dm m diameter, clothed with dark or rimose rough, the drooping 

 branches often armed with chestnut-brown or gray spines 2-3. 5 cm 

 long : leaves obovate, cuneate, broadly oval or suborbicular, the 

 blades i.5-4 cm long, i-4 cm wide, pointed or rounded at the apex, 

 narrowed or contracted or on leading shoots sometimes rounded 

 at the base, the margins dentate and glandular ; they are slightly 

 pubescent when young, becoming glabrate in age, or with some 

 persistent pubescence along the midrib and in the axils of the 

 veins beneath, firm to subcoriaceous in texture, dull to bright 

 green, fading in autumn with tones of yellow, brown and orange : 

 petioles 5 mm -2 cm long, margined, pubescent, glandular : flowers 

 i6-2o mm wide, opening near the end of April and when the leaves 

 are less than half grown ; they are produced in simple, glandu- 

 lar-bracteate, 3-5-flowered corymbs which terminate short, leafy 

 branchlets : pedicels and hypanthium pubescent : sepals 4-5 mm 

 long, glandular-serrate, reflexed after anthesis : stamens 20, the 

 anthers pink : fruit, which ripens and falls the last of August
