BILTMORE BOTANICAL STUDIES 



hypanthium sparingly pilose or glabrous : sepals 4~5 mm long, 

 entire or slightly serrate, reflexed or spreading after anthesis : 

 stamens normally 10: fruit globose or subglobose, 6-g mm thick, 

 the flesh thin and firm : nutlets 3-5, 5-6 mm long, the lateral sur- 

 faces nearl/ plane : hypostyle about 4 mm long. 



Cratcpgus denaria grows on or near the banks of streams in eastern Missis- 

 sippi and is not uncommon at Columbus (type locality). 



The original specimens, consisting of flowers (H88) and fruit (//jig6), are 

 preserved in the Biltmore Herbarium. 



Crataegus crocina n. sp. 



A tree 4-6™ tall with a short trunk sometimes i-i.5 dm in 

 diameter, covered with ashy-gray or brownish-black scaly bark, 

 the spreading branches forming a wide crown : leaves oblong- or 

 obovate-cuneiform, the blades 2-5. 5 cm long, i~3 cm wide, either 

 rounded or pointed at the apex, cuneate at the base, the borders 

 serrate, except near the base ; they are bright green and glabrous 

 or glabrate on the upper surface at maturity, pale or whitened and 

 pubescent beneath, especially along the midrib and principal 

 veins, and when young are more or less pubescent on both sur- 

 faces, firm to subcoriaceous in texture, fading in autumn with 

 tones of yellow, orange and brown : petioles 5-i5 mm long, mar- 

 gined, pubescent, at least when young : flowers i2-i6 mm wide, 

 opening about the 20th of April and when the leaves are almost 

 or quite fully grown ; they are produced in subsimple or compound, 

 few- to many-flowered corymbs, the lowest branches of which are 

 axillary : pedicels and hypanthium pilose-pubescent : sepals 

 3.5~5 mm long, entire or slightly serrate, spreading or reflexed after 

 anthesis : stamens normally 20, the anthers yellow : fruit, which 

 ripens in October, oval or oblong, 8-1 i mm thick, yellow at ma- 

 turity : nutlets usually 2, about j mm long, the ventral surface 

 nearly plane : hypostyle 4-5 mm long. 



Cratcegus crocina is common in low woods seven miles west of Opelousas, 

 Louisiana (type locality), growing with oaks, hickories, gums and dogwoods. 



The type specimens, which are deposited in the Biltmore Herbarium, repre- 

 sent both flowers and fruit {HJ133) from the same tree. 



Crataegus albicera n. sp. 



A tree sometimes 7-8™ tall with a trunk 2 dm in diameter, 

 clothed with dark gray or brownish scaly bark, the spreading
