"Pinus ponderosa" trees are predominant with nearly complete undergrowth of "Carex heliophila". These include the brown alga, "Dictyota menstrualis" and the sun sponge ("Hymeniacidon heliophila"). The larvae feed on various sedges, including "Cyperus esculentus" and "Carex heliophila". Nervonic acid is also found in "Cardamine gracea", "Heliophila longifola", and "Malania oleifera". Many types of animals consume this plant, particularly "C. inops" subsp. "heliophila". Heliophila is a genus of flowering plants in the family Brassicaceae. "Heliophila" is one of only two genera of Brassicaceae endemic to southern Africa. "Heliophila" is regarded as one of the most diverse genera in the family Brassicaceae.
