Hypericum canadense L.
Lesser Canadian St.john's-wort
Florida native
An occasional wildflower of pond margins, bogs and wet flatwoods in northeast Florida and some central and western panhandle counties. The range includes all of the United States east of the Mississippi River plus Iowa, Minnesota, Oregon & Washington state. Also found in eastern Canada.
The four-anlged usually single stems grow from 5-75cm (2 to 29-1/2 in.) tall, sometimes branching in the upper part. Leaves are opposite with pairs spirally arranged going up the stem. The linear to linear-oblanceolate leaves have translucent dots and are typically one-nerved but occasionally three-nerved. The yellow five-petaled flowers may appear singly or in simple cymes. The petals are often about the length of or shorter than the sepals. The 15 stamens are grouped into three loose clusters.
Hypericum canadense leaves have a similar appearance as those of H. cistifolium, the latter having petals that are significantly longer than the sepals and many more than 15 stamens.
Hypericum canadense is a member of the Clusiaceae - Mangosteen family.
