Pollination ecology and endemic adaptation of Pedicularis howellii Gray (Scrophulariaceae)


, : Pollination ecology and endemic adaptation of Pedicularis howellii Gray (Scrophulariaceae). Plant Species Biology 1: 163-172

Pedicularis howellii, a root hemiparasite confined to the Siskiyou mountains of California and Oregon, USA, was found at altitudes between 1280 and 1920 m at the edges of mixed conifer forests.
