be tied up by the great coastal plain flood, but while waiting there 
found Crataegus flava Aiton in good fruiting condition and was 
thus able to identify surely, for the first time in America, the 
plant described by Aiton from material in the Kew Gardens in 
1789. Then I went to Ashe’s stations at Bladenboro, Raleigh, 
King’s Mountain, Charlotte, Salisbury, China Grove, and 
Catawba, North Carolina; stopped at Biltmore, and, finding 
Crataegus in extra fine condition there, made a complete collec- 
tion of the species of the region. Then I visited Ashe’s stations 
at Hot Springs, Paint Rock, and Marion, North Carolina, and, 
going over the mountains by the new Clinchfield R. R., stopped 
at Bristol, Virginia, and then at Mountain City, Tennessee. 
From Mountain City, Tennessee, I drove over forty miles across 
the Stone Mountains to Beaver Creek, Ashe County, North 
Carolina. This was the type region of several of Ashe’s species 
and the most important region to look for northern forms. 
Mountain City, Tennessee, is at 2,500 feet elevation, the pass 
over Stone Mountain 3,500 feet, and Beaver Creek over 3,000 
feet, while no part of Ashe County is lower than 2,500 feet. 
I was very successful in my search here, getting Crataegus 
amara Ashe, the type of a southern group which I had not seen 
in Mr. Ashe’s herbarium, and a number of northern species, 
including C. rotundifolia (Ehrh.) Borckh, which proved to be 
Ashe’s C. viminea, a fact which I had suspected both from the 
description and from material collected by Boynton. 
I next went to West Nashville and Lookout Mountain, 
h 
C. collina, and Mr. Beadle got several of his types. Then I 
started north again, stopping at Salisbury, Chapel Hill, Southern 
Pines, Sanford, Fayetteville, and Kinston, North Carolina, and 
securing much valuable material and information. 
In May, 1909, the Garden sent me to explore the Cumberland- 
Tennessee region in Western Kentucky. On my way down, I 
stopped at White Sulphur Springs, West Virginia, finding both 
Crataegus and Malus in fine flowering condition; then I went to 
Clifton Forge, Virginia, and secured Crataegus Vailae Britton in
