old Crataegus collection near the Forest Hills gate, are as handsome 
as any Thorns in the collection. They are trees some twenty feet high 
with horizontally spreading branches forming a rather flat-topped head 
broader than the height of the tree. The leaves are thick and coria- 
ceous, very dark green and lustrous on the upper surface, from two 
to three inches long and from an inch to an inch and a half wide, and 
in the autumn turn bright scarlet and orange. The flowers are pro- 
duced in broad, many-flowered clusters which cover the branches from 
end to end, and are about three-quarters of an inch in diameter with 
from fifteen to twenty stamens and yellow anthers. The fruit, which 
does not ripen until the end of October, hangs in drooping clusters, 
and is dull red, thickly covered with a glaucous bloom, and occasionally 
nearly half an inch in length. Crataegus nitida must find a place 
among the six most beautiful Hawthorns which can be grown in Mass- 
achusetts. 
Crataegus punctata is the type of the Group which takes its name from 
this tree, and is represented by at least a dozen species. Of these 
five species are found in the region east of the Mississippi River and the 
others in the territory extending from Missouri to eastern Texas. The 
species are distinguished by short- stalked leaves wedge-shaped at the 
base, with prominent veins, flowers of medium size in wide, many- 
flowered clusters, with twenty or in the case of two species ten sta- 
mens, and yellow or rose-colored anthers, and by short-oblong to sub- 
globose often punctate fruit. The type of the Group, C. punctata, is a 
tree often thirty feet high with a trunk occasionally a foot in diame- 
ter, and stout horizontally spreading branches forming usually a round- 
topped or flat head occasionally fifty feet across. The flowers are 
about three-quarters of an inch in diameter and are arranged in many- 
flowered hairy clusters; there are twenty stamens, and on some trees 
the anthers are rose-colored, and on others they are yellow. The fruit, 
which ripens and falls in October, is short-oblong to subglobose, flat- 
tened at the ends, marked by numerous white dots, up to an inch in 
length and dull red on some trees and bright yellow on others, the 
trees with yellow anthers producing the yellow fruit. Crataegus punc- 
tata is one of the most distinct and generally distributed Thorns of the 
northeastern states, although it has not been found in eastern Massa- 
chusetts. In Canada it is common from the valley of the Chateaugay 
River in Quebec to that of the Detroit River in Ontario, and westward 
in the United States to central Iowa, the only place where it has been 
found west of the Mississippi River; it is very common in the middle 
states, ranging southward along the Appalachian Mountains, and as- 
cending in North Carolina and Tennessee to altitudes of nearly six 
thousand feet. Although one of the most distinct and perhaps more 
easily recognized at a glance than any other American Hawthorn, it 
escaped the attention of early American botanists or was entirely mis- 
understood by them, and was first distinguished by an Austrian botan- 
ist from plants cultivated in Europe. There are a number of plants 
on the southern slope of the Bussey Hill overlook. 
Crataegus succulenta. This is a native of a large and widely dis- 
tributed group now called the Macracanthae, although until recently
