Crataegus lanata n. sp. 



A large shrub or small tree 2-5™ tall with a short trunk i-i.5 dm 

 in diameter, clothed with dark, rough or rimose bark, the droop- 

 ing branches sometimes armed with stout, chestnut-brown or gray 

 spines i.5-2.5 cm long: leaves cuneate, the blades 2~4 cm long, 

 7 mm -2 cm wide, or on leading shoots often larger and broader than 

 long, mostly pointed at the apex, cuneate at the base, the borders 

 glandular and usually broken above the middle by one or more 

 short, point-like lobes ; they are tomentose, at least on the lower 

 surface at maturity, and when young are more densely coated 

 with tomentum, dull green, firm to subcoriaceous in texture, 

 fading with tones of brown, orange and yellow: petioles 5-15 mm 

 long, winged, glandular, tomentose : flowers, which open after 

 the middle of April and when the leaves are about half grown, 

 produced in simple, mostly 2-4-flowered corymbs : pedicels and 

 hypanthium densely tomentose : sepals 4-5 mm long, narrowly lan- 

 ceolate or almost linear, glandular, serrate : stamens 20, the 

 anthers light yellow or nearly white : fruit, which ripens and falls 

 in August, globose, 8-1 i mm in diameter: nutlets 3-5, 6~7 mm long, 

 the lateral surfaces nearly plane : hypostyle about 5 mm long. 



Crataegus lanata is represented in many herbaria and especially by the 

 specimens distributed by Mr. A. H. Curtiss (No. 6320) from near Stone Moun- 

 tain, Georgia. Grows in rocky woods and sandy soil from the valley of Yellow 

 river to northern Georgia and western North Carolina. 



The type material, which is preserved in the Biltmore Herbarium, was col- 

 lected near the banks of Yellow river, below McGuire's Mill, Gwinnett county, 

 Georgia, April 5, 1901 (B4T43) and June 21, 1899 {B5S7).
