1905] Robinson, A New Ranunculus 219 
and slender nearly straight branchlets marked by pale lenticels, dark 
orange-green when they first appear, light chestnut-brown and lustrous 
in their first winter, lighter-colored in their second season, and light 
gray-brown the following year, and armed with many stout slightly 
curved bright chestnut-brown shining ultimately dark gray-brown 
spines 4-5 cm. long. 
Hillsides, Deerfield River Valley, Windham County, Vermont; 
common. Wilmington and Whitington, W. H. Blanchard (no. 7), 
August 1902, W.W. Eggleston (nos. 3451, 3452 type! and nos. 3446, 
3449, 3453), May and September 1903. 
This species is named for William Henry Blanchard, an industrious 
and critical student of Crataegus and Rubus, and the discoverer of 
other interesting New England plants. 
INTRICATAE. 
CRATAEGUS PecKII, Sarg., RHODORA, v. 63, (1903). A specimen 
gathered at Great Barrington, Massachusetts, by Brainerd and 
Sargent on October 4, 1902, was doubtfully referred by me in 
RHODORA to this species. The flowers subsequently gathered by Mr. 
Eggleston showed that the Great Barrington shrub is C. Baxter:, 
Sarg., a common species in the neighborhood of Albany, New York, 
and in western New York and eastern Pennsylvania. C. Baxter 
was published in June 1903 in the Proceedings of the Rochester Acad- 
emy of Science (iv. 107) but the Pennsylvania plant had been published 
by Ashe as C. foetida in Ann. Carnegie Museum (i. pt. iii. 389) in 
May 1902, and his name must supercede C. Baxteri.
