calyx-lobes, which are bright red toward the base on the upper side; the flesh is thin, yellow, dry, and 
mealy, with a disagreeable flavor. The nutlets are usually three in number and are light chestnut- 
brown, prominently grooved and ridged on the back, with broad rounded ridges, and about a quarter of 
an inch long. 
Crategus Holmesiana grows on rich moist hillsides and the borders of streams and swamps, and 
is easily distinguished by its pale bark and the distinctly yellow color of the leaves, and in eastern 
New England by its large size. It is distributed from the neighborhood of Montreal and from 
southern Ontario to the coast of Maine, central and western Massachusetts, western New York, Rhode 
Island, and eastern Pennsylvania, being perhaps most abundant and attaining its largest size on the 
hills of Worcester County, Massachusetts.’ 
This handsome tree was named for Joseph Austin Holmes,’ director of the Geological Survey of 
North Carolina. 
1 Crategus Holmesiana is one of the species which has been long 
confounded with Crataegus coccinea of Linnzus. The oldest speci- 
men which I have seen is one in the Gray Herbarium, without 
date or name of collector, from northern New York. A specimen 
collected at Haverhill, New Hampshire, by Mr. Edwin Faxon in 
June, 1885, led to the investigation of this tree in New England, 
and its subsequent discovery in other parts of the country. 
2 Joseph Austin Holmes (November 28, 1859) was born in Lau-
