Mertensia lanceolata
 
Lance-Leaved Lungwort

Stem Leaf Top Close-Up

Oro Lake Regional Park
19-May-2007

Note the strigose pubescence.  The pubescence is more scattered on other parts of the leaf.

Note that the key to the species in Budd's Flora requires "flowers 10-15 mm long; NOT [flowers 15-25 mm long]", while the key to the genera in the same flora requires "flowers smaller than 12-18 mm long".  The flowers of the specimen illustrated here are about 12 or 13 mm long.

Note also that  the key to the species in Budd's Flora requires "plants pubescent; NOT [plants entirely glabrous]", while the key to the species in Flora of Alberta requires "stems glabrous; NOT [stems pubescent]".  Both these statements are correct.  The stems are glabrous, but the leaves are scantily strigose.  Finally, the key to the genera in Flora of Alberta requires "plants usually rough-hairy; NOT [plants glabrous]".  This species is not really rough hairy.
