Streptanthus fenestratus not subdivided. Flowers occur at intervals along the upper stem with one or two leaflike green or purple-tipped bracts at the base of the raceme. Each flower has a tubular urn-shaped calyx of purple sepals just under a centimeter long. Light petals up to 1.5 centimeters long emerge from the tip of the calyx. The fruit is a flat, narrow silique up to 5 centimeters long. One of the main threats to this species is trampling by hikers. Streptanthus fenestratus Streptanthus fenestratus is an uncommon species of flowering plant in the mustard family known by the common name Tehipite Valley
Polygonum ramosissimum calyx. The calyx is around long and 5-parted with the outer three sepals longer than the inner sepals. The seeds are produced in fruits called achenes, which are egg-shaped, dark brown and around long. The achenes also have a smooth shiny surface. The late season achenes are larger, from 4 to 15 mm long. There are a number of forms and two subspecies, that vary in flower and foliage coloration. "Polygonum ramosissimum" has great morphological variability, which is notable on the same plant, between flowers and fruits produced early in the blooming season verses those produced late in the season,
