118 KEY AND FLORA 
Calyx tube 5-cleft, its lobes epigynous. Petals oblong. Styles 
5, united below; ovary 5-celled, 2 ovules in each cell, often 
only 1 maturing. Fruit small, berry-like.* 
1. A. canadensis Medic. Service Berry, JUNEBERRY, SHAD 
Busy, Sugar Pium, Sugar Pear, Witp Pear. A small tree, 
branches downy when young, soon becoming smooth. Leaves ovate 
to elliptical, finely and sharply serrate, acute at the apex, usually

appearing before or with the leaves. Flowers showy. Petals 4 or 5 
times the length of the smooth calyx lobes. Fruit globose, dark red, 
edible. In rich woods. Extremely variable in height and in shape 
of leaves.*

A. canadensis, but with the leaves broadly oval, ovate, or almost 
orbicular, and usually rounded at both ends. Woods and thickets,

persistent. Petals round. Stamens few or many. Styles 1-5, 
distinct ; ovules 1 in each cell. Fruit a small pome with bony 
carpels.* [The species are hard to distinguish and are not 
very perfectly defined. Probably more than 60 species occur 
within the limits of this flora. ] 
VII. FRAGARIA L. 
Perennial scape-bearing herbs, with runners. Leaves with 
3 leaflets; stipules united to the petiole. Flowers (of Ameri-
