Crategus glabriuscula, Sargent, Bot. Gazette, xxxi. 235 (1901). 
A tree, from twenty to twenty-five feet in height, with a tall straight stem often a foot in diameter 
covered with thin dark brown scaly bark, and long ascending branches forming a narrow head. The 
branchlets are slender, nearly straight or rarely somewhat zigzag, marked by numerous small pale 
lenticels, and unarmed or furnished with occasional very thin straight chestnut-brown lustrous spines 
generally from three quarters of an inch to an inch in length. The leaves vary from oblong-ovate to 
semiorbicular, and are acute and often short-pointed or rarely rounded at the apex, gradually narrowed 
from below the middle and decurrent on the long slender slightly grooved glandular petioles, coarsely 
and often doubly serrate usually only above the middle, with broad straight gland-tipped teeth, and 
sometimes divided toward the apex into two or three short acute lobes; when the flowers open about the 
first of April they are nearly fully grown, and are membranaceous and slightly pilose above, with scattered 
pale hairs which are most abundant along the base of the midribs and soon disappear; and at maturity 
they are subcoriaceous, hard, and firm in texture, dark green and lustrous on the upper surface, pale on 
the lower surface, from an inch and a half to two inches long and from three quarters of an inch to an 
inch wide, with thin light yellow midribs and primary veins extending obliquely toward the apex of the 
leaf and conspicuous secondary veins and reticulated veinlets. The stipules are linear, entire, and about 
a third of an inch in length. On vigorous leading shoots the leaves are often ovate, broadly cuneate 
at the base, much more coarsely dentate and more frequently lobed than the leaves of lateral branchlets, 
and from two inches to two inches and a half long and wide, with foliaceous lunate coarsely glandular- 
dentate stipules sometimes an inch broad. The flowers, which are about half an imch in diameter, are 
borne on long slender pedicels, in few-flowered rather compact thin-branched corymbs, with minute linear 
finely glandular-serrate caducous bracts and bractlets. The calyx-tube is broadly obconic, and the lobes 
are short, gradually narrowed from broad bases, acute, entire, villose on the upper surface, and reflexed 
after the flowers open. There are twenty stamens with elongated filaments and nearly white anthers, 
and five styles. The fruit, which ripens in September and often does not fall until late in the winter, 
hangs on slender stems in compact many-fruited drooping clusters; it varies from short-oblong to 
obovate or to nearly globose, and is dull orange color marked by minute dark dots, and about a 
quarter of an inch long; the calyx is conspicuous, with a deep broad cavity and spreading or closely 
appressed lobes which are but slightly enlarged, dull red on the upper side at the base, and often 
deciduous before the fruit ripens; the flesh is very thin, yellow, dry, and hard. The five nutlets are 
rounded and sometimes obscurely grooved on the back, and about three sixteenths of an inch long. 
Crategus glabriuscula inhabits the dry parts of the bottom-lands of the Trinity River and its 
branches near Dallas, Texas, where it grows in forests of Ulmus crassifolia and Celtis Mississippiensis, 
and where it was discovered in June, 1899, by Mr. Julien Reverchon.’ 
1 Julien Reverchon (August 3, 1837) was born in the little vil- tution of the first French Republic, and his father and uncle active 
lage of Diemoz near Lyons in France, of a family well known for participants in the Revolution of 1848. In 1855 he came with his 
its strong republican principles, his grandfather Jacques Reverchon father to Texas, where the family purchased a farm in the neighbor- 
having been a member of the convention which framed the consti- hood of Dallas. Here he was able to turn the knowledge of botany
