1899] STUDIES IN CRATA:GUS 409 
I take pleasure in naming the species in honor of Professor 
C.S. Sargent, Director of the Arnold Arboretum of Harvard Uni- 
versity, who first called my attention to specimens collected by 
him near Rome, Georgia, in April 1899. The type material, 
which I had the opportunity of selecting from thousands of 
examples near Valley Head, Alabama (type locality), is pre- 
served in the Biltmore Herbarium. 
Crategus Boyntoni, n. sp.—A tree seldom more than 6” in 
height, or more frequently a large branching shrub, 2-4” tall, 
frequenting the banks of streams and even the shallow, dry soil 
of old fields and upland woods: flowers, which expand about 
thetenth of May in the vicinity of Biltmore, N.C. (type locality), 
and when the leaves are almost fully grown, 1.75-2.25™ in 
diameter, produced in short, glandular-bracteate, 4—10-flowered 
corymbs: pedicels 7™"—1.5™ long, glabrous, bearing one or two 
glandular or pectinately-glandular bractlets : calyx obconic, 
smooth, the divisions acute, glandular serrate, 4-6"" long: petals 
White, nearly orbicular, or a little broader than long, with a short 
and broad claw at the base, g-12™" in diameter: stamens 10, 
6-9" long, the anthers light yellow: pistils 3-5, surrounded at 
the base with pale hairs: fruit dull, yellowish-green, flushed with 
lusset-red, depressed-globose, angled, 10-14™ high, 12-16™ 
broad, ripening and falling early in October: nutlets 3-5, hard 
and bony, 6—8™™ long, 4-5™™ measured dorso-ventrally, the back 
tidged and grooved and the lateral faces nearly plane, a volume 
of 125° containing about 1293 thoroughly clean and dry seeds: 
leaves at first membranaceous, becoming subcoriaceous with age, 
Yellowish-green on the upper, paler on the lower surface, glab- 
_ Tous, or with a few scattered hairs along the midrib and larger 
Veins, which are disposed in 4~—7 pairs; they are broadly ovate 
*Foval in outline, acute at the apex, rounded or narrowed at se 
base and prolonged into a margined, glandular petiole 1-2.5 
‘ong, or on vigorous shoots deltoid-ovate and truncate or sub- 
_ *©rdate at the base; the borders are sharply and ir regularly woul 
Tate, doubly serrate or incisely 5—7-lobed, the serratures minutely 
- Sland-tipped: stipules linear, glandular, caducous, or on strong
