rate : stamens normally 20, the anthers yellow : fruit globose, 

 bright red at maturity, 7~8 mm in diameter : nutlets 3-5, about 5 mm 

 long, the lateral surfaces nearly plane, and the back either smooth 

 or slightly ridged : hypostyle occupying about two-thirds of the 

 ventral angle. 



Cratcegus interior is abundantly represented in the flat woods near Chatta- 

 nooga, Tennessee (type locality). The type material, flowers (B4.243) and fruit 

 (B4243' 2 &s ) from the same tree, is preserved in the Biltmore Herbarium. 



Crataegus aemula n. sp. 



A shrub or small tree 3-5™ tall with a short, slender trunk 

 covered with smooth or slightly fissured and scaly dark gray or 

 brownish bark, the ascending or spreading branches forming an 

 irregular crown : spines 3-5 cm long, chestnut-brown or gray, or 

 frequently larger and compound : leaves broadly ovate, oval or 

 suborbicular, the blades 3~5 cm long, i.5-4 cm wide, acute at the 

 apex, rounded or contracted at the base, the margins serrate and 

 incised ; they are sparsely pubescent on the upper surface at the 

 time of unfolding, smoother beneath, but showing some short, 

 scattered hairs along the midrib and principal veins, becoming 

 in age glabrous or glabrate : petioles ^mm^^cm long, pubescent, 

 at least when young, margined, glandular : flowers 14-18™™ wide, 

 appearing when the leaves are about half grown, usually about 

 the 20th of April ; they are borne in subsimple, 5-10-flowered 

 corymbs : pedicels and hypanthium sparsely pubescent : sepals 

 lanceolate, about 4 mm long, glandular-serrate or pectinately-glan- 

 dular : stamens normally 10, rarely 12, the anthers purple: fruit, 

 which ripens and falls early in September, globose or subglobose, 

 io-i3 mm in diameter, red at maturity, the flesh firm : nutlets 3-5, 

 5-7 mm long, the lateral surfaces plane and the back either smooth 

 or shallowly grooved and ridged : hypostyle about two-thirds as 

 long as the ventral angle.

 tion of the state of Georgia, especially at Rome (type locality), where the species
