Madieae is a tribe of flowering plants in the family Asteraceae. It is sometimes considered a subtribe of Heliantheae. Notable species include the tarweeds of the Western United States as well as the silverswords of Hawaii.
Jensia rammii is a species of flowering plant in the family Asteraceae known by the common name Ramm's madia. It is endemic to California, where it is limited to the northern slopes of the Sierra Nevada and its foothills.

Helenieae is a tribe of the plant family Asteraceae. The type genus is Helenium, but the best known members of the tribe are the Gaillardia. Helenieae are usually placed in their own tribe, but some authors include this and several other tribes as subtribes within a broader definition of the tribe Heliantheae.
Jensia is a genus of flowering plants in the family Asteraceae, endemic to California.
Anisocarpus scabridus, the leafy raillardiopsis, is a North American species of flowering plants in the family Asteraceae.
Heliomeris multiflora is a North American species of flowering plants in the family Asteraceae called the showy goldeneye. It grows in Mexico and the western United States from Montana to Jalisco.
Diplacus is a plant genus in the family Phrymaceae, which was traditionally placed in family Scrophulariaceae. In the 2012 restructuring of Mimulus by Barker, et al., based largely upon DNA evidence, seven species were left in Mimulus, 111 placed into Erythranthe, 46 placed into Diplacus, two placed in Uvedalia, and one each placed in Elacholoma, Mimetanthe, and Thyridia. Diplacus used to be a separate genus from Mimulus, but it was merged into Mimulus no later than 1905, until the 2012 restructuring. Dry and rocky areas are preferred.
