2. Malusioensis (Wood) Britton. WrstTeRN CRAB APPLE. JOWA 
Crap Appie. Plate 78. Leaves oblong to ovate-oblong, 4-10 cm. 
(114-4 inches) long, 2-8 em. (#4-314 inches) wide, obtuse or acute 
at the apex, rounded or broadly cuneate at the base, dentate-crenate 
or doubly so, slightly pubescent above, becoming glabrous, dark 
green, slightly rugose above, densely white-tomentose below, re- 
maining so at least along the veins; petioles 1.5-4 em. (44-14% 
inches) long, densely white-tomentose; corymbs 2-5 flowered, ped- 
icles pubescent; calyx densely white-tomentose, calyx lobes lance- 
olate-acuminate, densely tomentose on both sides; flowers similar 
to those of Malus coronaria; fruit subglobose, without angles, green, 
2-3.5 em. (34-11% inches) thick, 2-8 em. (24-114 inches) long. 
Distribution. Indiana, central Kentucky, Louisana, Wisconsin, 
southern Minnesota, eastern Kansas and Texas. A tree, in habit, 
similar to Malus coronaria. 
Specimens have been seen from: Putnam (Grimes); Tippecanoe 
(Dorner). A fragment in the National Museum from New Albany, 
Floyd County, Ind., collected by C. F. Very, April 1896, No. 254781, 
may also belong to this species. 
This species seems rather uncommon as far east as Illinois, still, 
no doubt, other stations will be found in Indiana, now that it is 
known to occur in the State. 
2. AMELANCHIER. Tue Service BEerRRIEs. 
Amelanchier canadensis (Linnzeus) Medicus. JUNEBERRY. SERV- 
ICEBERRY. Plate 79. Bark light reddish-brown; leaves very broadly 
ovate to oblong, 4-8 em. (114-3 inches) long, acute, usually cordate 
at the base, sometimes rounded, finely serrate with incurved tecth, 
very hairy and folded together when very young, becoming glabrous 
above and below at maturity, frequently the under side persistently 
hairy, thick and firm, dark green above, paler beneath; petioles 4- 
2/5 the length of the blade; flowers appear in April or May when 
the leaves are expanding at the ends of the branches in loose or 
spreading racemes; fruit ripens in June or July, globose, red or 
purplish, about 7 mm. (14 inch) in diameter, sweet and edible. 
This tree varies greatly in its size, in the kind of soil and loca- 
tion where it is found, in the shape and pubescence of the leaves, 
in the size and shape of the petals and in the size and color of the 
fruit. These variations have led authors to describe several varie- 
ties. The accompanying plate is the typical leaf form of the State. 
The oblong type is seldom seen in the northern part of the State,
