Quite showy as in subalpine meadows, this subspecies (latifolia)is the tallest lousewort at the Park. The leaves are pinnately divided, and the stems are leafy. The upper lip of the flower is hoodlike. The inflorescence is hairy, and the flowers are often purplish, although in this photo they are greenish-yellow.

Much less common at the Park, this is variety flavida. Here it grows alongside the Naches Peak trail near the eastern boundary. It differs in the more yellowish color of the flowers and in the details of the sepals.

The sepals are glandular and slender in variety flavida, and the hairs are limited to the calyx lobes and bract margins.
