Fruit

One Mile West of Melita, MB
29-July-2015

The fruit consists of an achene surrounded by fleshy tissue derived from the hypanthium.  This is an example of an accessory fruit.

Hippophae rhamnoides is a species introduced to North American from Eurasia that occasionally escapes from cultivation.  This plant was found in the Gerald W. Malaher Wildlife Management Area.  This property blew hard during the 1930s.  As part of a successful attempt to rehabilitate the land, many exotic species were planted here.
