250 Elevexth Annual Report 



2. Malus ioensis (Wood) Britton. Western Crab Apple. Iowa 

 Crab Apple. Plate 78. Leaves oblong to ovate-oblong, 4-10 cm. 

 (13/2-4 inches) long, 2-8 cm. (M-3J4 inches) wide, obtuse or acute 

 at the apex, rounded or broadh' 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 cm. {}/2-^}/2 

 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 cm. i^-iyi inches) thick, 2-3 cm. (M-lM 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 Xew 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 The Service Berries. 



Amelanchier canadensis (Linnaeus) jMedicus. Juneberry. Serv- 

 ICEBERRY. Plate 79. Bark light reddish-brown; leaves very broadly 

 ovate to oblong, 4-8 cm. (13/2*3 inches) long, acute, usually cordate 

 at the base, sometimes rounded, finely serrate with incurved teeth, 

 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 3^- 

 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 

 purphsh, about 7 mm. (i<4 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,
