Furbish's lousewort flowers are small, yellow and snap-dragon like. Rare perennials include the Siskiyou fireweed ("Epilobium siskiyouense"), and several types of lousewort ("Pedicularis"). The meadows have vegetation of anemones, "Potentilla", lousewort, wild "Salvia" and thistles. Like many species in the broomrape family, the lousewort is a root-parasite. Marsh lousewort is a semi-parasitic plant, the roots sucking nourishment from adjacent plants. "Pedicularis furbishiae" (Furbish lousewort) and "Aster cordifolius" L., var. "furbishiae".
