trunk and larger branches dark ashy-gray, usually blackened 

 near the base, rough ; of the branches gray tinged with reddish 

 brown, the growth of the season bright reddish-brown, marked 

 with small lenticels : spines stout, gray or chestnut - brown, 

 2. 5—3. 5 cm long : leaves obovate or broadly cuneiform, on the 

 shoots frequently broadly obovate or elliptical, 2-6. 5 cm long, 

 including the petioles, ynm_^cm broad, either rounded at the 

 apex and often with a short and abrupt point or truncate, the 

 base wedge-shaped or more abruptly narrowed and extending 

 into gland-bearing, margined petioles, ^mm_ I# ^cm long; they are 

 glabrous or with a few hairs when very young, bright glossy 

 green, firm in texture, the margins irregularly serrate or finely 

 serrate-dentate : flowers, which appear when the leaves are nearly 

 fully grown, produced in glabrous or very sparsely weak-hairy 

 3-10-flowered simple or compound corymbs, i2-i5 mm in diameter, 

 opening in the vicinity of Montgomery, Alabama (type locality), 

 early in April : pedicels 6 mm — i.5 cm long, glabrous or with a few 

 weak hairs, bearing one or more narrow, glandular, caducous 

 bractlets : calyx obconic, glabrous, the divisions very long and 

 narrow, 4. 5-6 mm long, .5-. 75 mm wide or slightly more in mature 

 fruit, glandular-serrate, reflexed after anthesis : petals orbicular 

 or rather longer than broad, 6-7 mm wide, the claw at the base 

 relatively short and broad, the upper borders erose : stamens 

 normally 20, 4-5 mm long, the anthers light yellow : styles mostly 

 2-3, surrounded at the base with pale hairs : fruit oblong, red, 

 i-i.5 cm long, 8 mm -i cm broad, ripening and falling by or before 

 the middle of August : nutlets usually 2-3, 8-g mm long, 3-4 mm 

 measured dorso-ventrally, hard and bony, the back grooved and 

 ridged and the ventral faces nearly plane. 



Crataegus teres is possibly best contrasted with C. alabamensis , 1. c. , from 

 which it differs mainly in the glabrate corymbs, leaves and shoots and the smaller 

 fruit. The original specimens, which are preserved in the Biltmore Herbarium, 

 were gathered in pine woods near Montgomery, Alabama. 



Crataegus sinistra n. sp. 



A small tree 4-5™ tall, with a slender trunk seldom more 

 than i dm in diameter, clothed with scaly dark gray bark which 

 is frequently tinged with brown and much blackened near the 

 base ; or more frequently a large much-branched shrub with one
