140 SILVA OF NORTH AMERICA. ROSACEZ. 
broad, prominently ridged on the back, with broad rounded ridges, and penetrated on each of the inner 
faces by a broad deep depression. 
Crategus succulenta is common from the valley of the St. Lawrence River near Montreal to the 
coast of New England, and through northern New York and southern Ontario to northern Illinois, 
growing on open hillsides often on limestone. First distinguished in Europe from cultivated plants, 
and long an inhabitant of American and European gardens, it was formerly confounded with Crataegus 
coccinea by American botanists. 
1 The earliest mention of Crategus succulenta was in the seed-list 
of the Gottingen Botanic Garden for the year 1823, when the name 
only is mentioned; and a Mespilus succulenta appears without de- 
scription in the second and third editions of Sweet’s Hortus Botani- 
cus published in 1830 and 1839. This species is sometimes found 
in gardens under the name of Crategus Downingii, a name which 
has probably never been published. Plate No. exxxi., in the fourth 
volume of this work, purporting to represent Crategus coccinea, var. 
macracantha, properly represents Crategus succulenta, as I now 
understand this species. 
The range of Crategus succulenta is still very imperfectly known.
