slender slightly zigzag glabrous branchlets dark orange color and

Clay soil near the borders of woods, Rochester, J. Dunbar ( # L, 

 type), May 31, 1901, J. Dunbar and C. S. Sargent, September 27, 

 1901, September 19 1902; Rochester (Knickerbocker woods), 

 Baxter and Dewing (;^304), May 21 and September 25, 1905. 



Formerly referred to Crataegus pedicellata Sargent, the 

 " L " tree of Rochester is distinct from that species in its larger 

 flowers peculiar in the development of sacklike cavities at the base 

 of the petals, by its pink not dark rose colored anthers, by the much 

 larger and more lustrous fruit usually mammillate at the base and 

 ripened 10 to 12 days earlier, and by its convex leaves. In habit, 

 in its large and abundant flowers, and in the large and bril- 

 liant abundant fruits, C. g 1 o r i o s a is not surpassed in beauty 

 by any North American Crataegus.
