deciduous bractlet : calyx obconic, pubescent, the lobes lanceo- 
late, glandular-serrate, persistent : stamens normally 20, 4-6™" 
long: pistils 3-5, surrounded at the base with pale hairs: fruit 
large, red, or orange-red, globose, 10-13”" in diameter, pubes- 
cent or smooth, punctate, ripening in October: nutlets 3-5, 
6-g™ long, 4-5"" from back to inner angle, either furrowed 
on the dorsal side or with a blunt ridge and two grooves, the 
lateral surfaces nearly plane, a volume of 125° containing about 
1490 clean and dry seeds; cavity 4-6"" wide: bark of the 
trunk, which is from 1—2°" in diameter and I-—2 meters long, 
close or slightly fissured and scaly, ashy-gray or darker in color 
and frequently armed with simple or branched spines: branches 
clothed. with smooth, gray or light brown bark, and_ bearing 
straight or curved chestnut-brown or gray spines 3-6™ long,

Crategus Harbisoni was discovered by Mr. T. G. Harbison of 
the Biltmore Herbarium, for whom the species is named, on the 
limestone hills and ridges near Nashville, Tennessee, where 
numerous examples were observed at intervals during the past 
summer. 
The new species probably belongs to a group of which C. 
triflora Chapm. and the C. austromontana previously proposed are 
types. From the former it may be separated by the compound, 
many-flowered corymbs, and from the latter by its greater size, 
numerous stamens, spiny branches, large flower-clusters, and the 
different habit of growth. The type material is preserved in the 
Biltmore Herbarium. 
Crategus silvicola, n. sp.—A tree, attaining in low moist 
woodlandsa height of 6-10”, or in upland forests a shrub with 
one or more stems, 1—s™ tall: trunk, which is sometimes 2 
in diameter, covered with a close or slightly fissured and scaly, 
gray or reddish-brown bark, and armed with stout, branched 
spines: branches, which are spreading or ascending and form 4
