About
Ourisia crosbyi is a species of flowering plant in the family Plantaginaceae that is endemic to the South Island of New Zealand. Leonard Cockayne described O. crosbyi in 1915. Plants of this species of New Zealand foxglove are showy, perennial, large-leaved, tufted, rhizomatous herbs that are hairy with non-glandular hairs. They have serrate, ovate, hairy leaves. The flowers are in whorls in each node, with a regular calyx, and a large, white irregular corolla. The corolla tube is yellow with three lines of yellow hairs inside. It is found in montane forests and is listed as Not Threatened.
