|discussion=<p><i>Bartsia alpina</i> has been reported to parasitize a wide range of hosts, including members of <i>Ericaceae</i>, Fabaceae, and <i>Poaceae</i> (U. Molau 1990). Outside the flora area, it occurs throughout northern Europe and in disjunct populations in the Alps and Pyrenees.</p><!--
--><p><i>Bartsia alpina</i> has been divided into varieties based primarily on variation in the color of the corolla. The most common form has violet corollas; other populations throughout the range occasionally include individuals with pale violet to yellow corollas. U. Molau (1990) reported that these forms are likely an expression of phenotypic variation induced by infection by either a gall fly or imperfect fungus.</p>
