twenty-five to thirty feet, with a trunk occasionally six to eight 
feet high, the branches are spreading and ascending, and 
when the tree stands alone in the open, forms a dense round 
head. The leaves are ovate, and ample, always showing a 
convexity of surface. The large blossoms, in conspicuous clus- 
ters, have from seven to ten stamens and pale pink anthers. 
The short, oblong, lustrous crimson, large fruits in bold clusters 
ripen in September and fall about the end of October. This is a 
common species in Western New York, and Dr. C. S. Sargent 
in his description of it, says: “is not surpassed in beauty by any 
North American Crataegus.” 
Dilatatae Group. This contains only six species but it has 
two very decorative plants. C. coccinioides is a tree twenty 
feet, with stout spreading branches, forming a broad handsome 
head. The leaves are oval to broadly ovate and always appear 
very distinctive. The large flowers in large clusters with twenty 
stamens and rose-colored anthers are very showy. The dark 
crimson, lustrous, roundish fruits in small clusters ripen in 
October and are showy until the middle of November. C. 
durobrovensis rarely assumes the dimensions of a tree, but is 
generally an arborescent shrub from twelve to sixteen feet, with 
spreading and ascending branches forming a broad open head. 
The leaves are ovate to oval, and deep green. The large blos- 
soms, with twenty stamens and large, pale rose-colored anthers, 
are borne in conspicuous clusters. The roundish, lustrous crim- 
son fruits ripen about the first of October and are most orna- 
mental until the middle of December — and if the weather is not 
unusually severe, the fruit will occasionally be in good condition 
until January. This Hawthorn is not surpassed by any other 
in North America as a late fruiting ornamental. 
Intricatae Group. In this group are a number of beautiful 
and extremely desirable garden plants because, with a few ex- 
ceptions, they are of small size, begin to flower and fruit at five 
or six years of age, and the foliage of nearly all of the species 
assumes bright orange-red tints in the autumn. C. Bissellii is a 
low spreading shrub not more than six or seven feet tall. The 
oblong-ovate leaves are dark green. The ten-stamened flowers 
with pink anthers are borne in small clusters. The short- 
oblong fruits have a reddish color tinged with green, and are 
ripe in October. C. foetida is an intricately branched arbor- 
escent shrub about twelve feet tall, with a round-topped head. 
The leaves are ovate to oval, always marked by a concavity of 
surface, and are bluish green. The ten-stamened flowers with 
cream-white anthers are produced abundantly in small corymbs. 
The subglobose fruits, borne in great abundance, are orange-red, 
ripen in October, and fall about the middle of November. 
C. Peckii is a broad-spreading shrub from five to six feet tall, 
with oblong to oval leaves and with a usually concave surface. 
The flowers, with ten stamens and pink or pale purple anthers, 
are borne on few-flowered corymbs. The short-oblong, yellow 
green fruits, tinged with red, are produced in erect clusters and 
ripen in October. 
Anomalae Group. Crataegus Dunbar ii is a low-spreading 
horizontally branched arborescent shrub, inclined to grow to 
one stem, becoming twelve to fourteen feet tall and forming a 
round, well balanced head. The leaves are semi-orbicular,

In the Arnold Arboretum where this specimen has been allowed to make its growth in its own way 
we can realize fully the natural habit, spreading and graceful. Beautiful in form, and in flower and fruit
