Orthocarpus
''Orthocarpus'', or owl's-clover, is a genus of flowering plants in the family Orobanchaceae (broomrapes). They are native to North America. A number of species formerly included in ''Orthocarpus'' have been transferred to the genus ''Castilleja'', which includes the plants commonly known as Indian paintbrush. Plants of the genus are generally less than in height. Like their close relatives in genus ''Castilleja'', ''Orthocarpus'' are root hemiparasites, capable of photosynthesis but extracting water and mineral nutrients through attachment to the roots of host plants. Some animal species such as the Edith's checkerspot butterfly use these plants as hosts during ovipositing.

Edith's Checkerspot
Edith's checkerspot (''Euphydryas editha'') is a species of butterfly in the family Nymphalidae. It is a resident species of western North America and among the subspecies, entomologists have long been intrigued by their many phenotypic variations in coloration, wing length, and overall body size. Most populations are monophagous and rely on plants including ''Plantago erecta'' and '' Orthocarpus densiflorus'' as its host species in developing from eggs through to larvae, pupae, and mature butterflies. Males exhibit polygyny whereas females rarely mate more than once. Males devote most of their attention to mate acquisition, and such mate locating strategies such as hilltopping behavior has developed. Climate change and habitat destruction has impacted certain subspecies. Two subspecies in particular, ''Euphydryas editha quino'' and '' Euphydryas editha bayensis'', are currently under protection via the Endangered Species Act. Description The Edith's checkerspot can be identifie ...

Orthocarpus Pachystachyus
''Orthocarpus pachystachyus'' is a rare species of flowering plant in the broomrape family known by the common names Shasta owl's-clover and Shasta orthocarpus. It is endemic to central Siskiyou County, California, where it is so rarely seen it was thought to be extinct until 1996, when eight individuals were located.The Nature Conservancy1997 Species Report Card Page 17. The plant grows in an isolated wilderness but since it apparently only occurs on one single hillside it is considered very vulnerable to extinction. Description This is a small annual herb producing a stout, hairy, glandular stem up to about 20 centimeters tall. The narrow leaves are up to 5 centimeters long, the upper ones sometimes divided into three to five lobes. The inflorescence is a dense cylindrical spike of wide oval purple-green bract In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis or cone scale.

Castilleja
''Castilleja'', commonly known as paintbrush, Indian paintbrush, or prairie-fire, is a genus of about 200 species of annual and perennial herbaceous plants native to the west of the Americas from Alaska south to the Andes, northern Asia, and one species as far west as the Kola Peninsula in northwestern Russia. These plants are classified in the broomrape family Orobanchaceae (following major rearrangements of the order Lamiales starting around 2001; sources which do not follow these reclassifications may place them in the Scrophulariaceae). They are hemiparasitic on the roots of grasses and forbs. The generic name honors Spanish botanist Domingo Castillejo. Ecology ''Castilleja'' species are eaten by the larvae of some lepidopteran species, including '' Schinia cupes'' (which has been recorded on ''C. exserta'') and ''Schinia pulchripennis'' (which feeds exclusively on ''C. exserta''), and checkerspot butterflies, such as ''Euphydryas'' species. Pollinators aid these plants in ...
