 showing leaves and 

 nearly mature fruit. 



The edible glabrous fruit is a bluish or purplish globe-shaped pome 5 to 9 mm in 

 diameter (fig. 5). It is five-celled. Each cell contains one or two seeds. Saskatoon 

 serviceberry averages 45,395 cleaned seeds per pound (lOO/g) [Plummer and others 1968). 



Considerable variation is present in the shape, size, amount of pubescence, and 

 serrations on leaf margins (fig. 6). Seed size is also highly variable. 



Flowers bloom during May and June and fruits ripen during July and August. Numer- 

 ous blossoms occur almost every year, but because of frost and juniper rust {Gymnospor- 

 angium) infestations, good seed crops may only be produced every 3 to 5 years.
