102 SILVA OF NORTH AMERICA. ROSACER. 
glandular-serrate, and from one quarter to one half of an inch long. The leaves turn brilliant orange 
and scarlet in the autumn before falling. The flowers are produced in broad leafy pubescent slender- 
branched cymes with lanceolate acute minutely glandular-serrate bracts and bractlets. They are half 
an inch across and have a strong disagreeable odor, and in Texas open as early as the middle of March 
and at the north in the middle of June, or some two weeks later than those of the forms of Crategus 
coccinea with which this species has often been confounded. The calyx is coated with pale tomentum, 
and is obconic with long lanceolate acute taper-pointed persistent lobes, which are deeply or pinnately 
serrate and usually glandular, reflexed after anthesis, and equal or exceed in length the obovate erose 
white petals, and glabrous pistils, which are two to five in number. The fruit is pear-shaped or rarely 
subglobose and half an inch broad, with a shallow cavity surrounded by the remnants of the calyx-lobes, 
thin dry flesh, and short obtuse thick-walled nutlets rounded and sometimes obscurely two-grooved on 
the back ; it is erect and dull red, and remains on the branches with little loss of color until the leaf- 
buds unfold in the following spring. 
Crategus tomentosa is distributed from the valley of the Hudson River near Troy to eastern 
Pennsylvania,” and ranges westward through central New York to central Michigan, and Missouri; it 
occurs on the Alleghany Mountains from northern Georgia to central Tennessee, and extends through 
Arkansas to eastern Texas.’ It usually grows in low rich soil in the neighborhood of streams and on 
the margins of the forest, and, except in western New York and southeastern Missouri, is not known to 
be very common. 
The wood of Crategus tomentosa is heavy, hard, and close-grained, and contains numerous thin 
medullary rays; it is bright reddish brown, with thick lighter colored sapwood. The specific gravity of 
the absolutely dry wood is 0.7585, a cubic foot weighing 47.57 pounds. 
Crataegus tomentosa is often found in English gardens, where it was introduced by Lee & Ken- 
nedy in 1765,* and in those of France and Germany. The brilliant color of its foliage in autumn and 
the persistence of the fruit on its branches during the winter constitute its chief value as an ornamental 
plant.
