78 MISSOURI BOTANICAL GARDEN. 
1909, October 11, 1911; 95, also numbers 87, 82, 91, 95, 96, 
97, 98, 100, May, 1909); Clarksville, Pike County (John 
Davis, 68, May 15, 1909; 64, May 16, 1909, September 3, 
1911). 
I am glad to associate the name of the Reverend John 
Davis of Hannibal with this plant for he is a zealous student 
of Crataegus and the other trees of northeastern Missouri, 
a region which as well as the rest of the state north of the 
Missouri River has been strangely neglected by botanists. 
Previously described species of the Viridis Group, with the 
exception of Crataegus furcata Sargent from southwestern 
Missouri, grow on bottom-lands often inundated during part 
of the year, and species with rose-colored or pink anthers 
are extremely rare, only three having been described. Of 
these, two are from southeastern Tennessee and the other 
from the swamps of the Red River near Fulton, Arkansas. 
Mr. Davis’s discovery of this species and two others of this 
group growing on high ground at least one hundred miles 
north of any reported station of a species of this group is 
certainly interesting. 
Crataegus Pechiana, n. sp. 
Leaves rhombic to obovate or ovate, acuminate, gradually nar- 
rowed and cuneate at the entire base, and finely often doubly serrate 
above, with incurved glandular teeth; about half-grown when the 
flowers open from the 10th to the middle of May and then yellow- 
green, slightly hairy along the upper side of the midribs, and fur- 
nished with large tufts of persistent hairs in the axils of the veins 
below, and at maturity thin but firm in texture, dull yellow-green on 
the upper surface, paler on the lower surface, 3-3.5 cm. long and 
2-2.5 em. wide, with slender midribs and 8 or 4 pairs of thin primary 
veins; petioles slender, wing-margined at the apex, villose on the 
upper side, usually becoming red in the autumn, 8-12 mm. in length; 
leaves on vigorous shoots mostly broadly ovate, abruptly acuminate, 
cuneate at the base, more coarsely serrate, occasionally slightly lobed, 
often 4 cm. long and 3 cm. wide, with linear entire caducous stipules. 
Flowers 1.3-1.5 cm. in diameter, in many-flowered glabrous corymbs, 
with linear obovate to linear bracts and bractlets, the lower peduncles 
from the axils of upper leaves; calyx-tube narrowly obconic, glabrous, 
the lobes gradually narrowed from wide bases, acuminate, entire, 
glabrous, reflexed after anthesis; stamens 15; anthers pink; styles 5. 
Fruit ripening in October, on drooping pedicels, in few-fruited clus-
