 high, glandular, soft-downy, leaves ovate or narrower, 6-12 lines long, 3-5 nerved, 

 entire or sparingly toothed: calyx 3-6 lines long: corolla 3-5 lines long, nearly regular 

 but limb very small, white.

C. parviflora, Bong., is C. Douglasii, Benth., in Bay-Meg. Bot. 



ORTHOCARPUS. 



O. versicolor, Greene. Slender, slightly reddish, mostly simple, 6 inches high or
