Malacothamnus (bushmallow) is a genus of shrubs and subshrubs found throughout much of mainland California and on three of the Channel Islands. Outside of California, Malacothamnus is known from the northern half of Baja California, from a disjunct location in central Arizona, and possibly from a historic location that may have been in southern Arizona or adjacent Mexico. Plants of this genus are most commonly found in early-successional, post-burn plant communities. Malacothamnus are currently thought to be most closely related to the Iliamnas of the US interior and the Phymosias of Mexico, Central America, and the Caribbean.
Epilobium hirsutum is a flowering plant belonging to the willowherb genus Epilobium in the family Onagraceae. It is commonly known as the great willowherb, great hairy willowherb or hairy willowherb. Local names include codlins-and-cream, apple-pie and cherry-pie.
Dudleya palmeri is a species of succulent plant in the family Crassulaceae known by the common name Palmer's liveforever. This Dudleya is endemic to California where it grows along the coast. It is characterized by orange to red over yellow or pink flowers.

Malacothamnus davidsonii is a species of flowering plant in the mallow family known by the common names Tujunga bushmallow and Davidson's bushmallow. It is endemic to Los Angeles County, California, where it primary occurs in and near Big Tujunga Canyon, Little Tujunga Canyon, and Tujunga Wash. The common name Tujunga bushmallow alludes to its geographic distribution. Plants of what has historically been considered Malacothamnus davidsonii from Monterey and San Luis Obispo counties in California were described as the new species Malacothamnus discombobulatus in 2023 based on phylogenetic, morphological, and geographic evidence.
Malacothamnus fasciculatus, with the common name chaparral mallow, is a species of flowering plant in the mallow family. It is found in far western North America.
Malacothamnus palmeri is a species of flowering plant in the mallow family known by the common names Cambria bushmallow and Palmer's bushmallow. It is endemic to San Luis Obispo County, California, where it is known from the Santa Lucia Mountains.
Quercus parvula, the Santa Cruz Island oak, is an evergreen white oak found on north-facing Santa Cruz Island slopes and in the California Coast Ranges from Santa Barbara County north to Mendocino County. It was taxonomically combined with Quercus wislizeni until resurrected as a separate species by Kevin Nixon in 1980. The type locality of Q. parvula var. shrevei is Palo Colorado Canyon in Monterey County. It is placed in Quercus section Quercus.
Drosera peruensis is a carnivorous plant of the genus Drosera, commonly known as the Peruvian sundew. This Drosera species was first identified in Peru in 2002 by Tânia Regina dos Santos Silva and Mireya D. Correa following work to update the genus Drosera for the reference text, Flora Neotropica..
Malacothamnus enigmaticus is a species of flowering plant in the mallow family known by the common name enigmatic bush-mallow. It is endemic to the Peninsular Ranges of California and Baja California, Mexico extending from the San Ysidro Mountains in the north to the Sierra de San Pedro Mártir in the south. It was first collected in 1938 and described as a new species to science in 2019. Prior to 2019, it had been mistakenly assigned to Malacothamnus aboriginum and Malacothamnus densiflorus.
Malacothamnus involucratus is a species of flowering plant in the mallow family known by the common name Carmel Valley bushmallow. It is likely endemic to Monterey County, California, where it is known from Carmel Valley and the Jolon region. A single specimen is attributed to San Luis Obispo County, California but the origin of this specimen is questionable.
Malacothamnus mendocinensis is a species of flowering plant in the mallow family known by the common name Mendocino bushmallow. It is endemic to Mendocino County, California, where it is known from only two populations. It was presumed extinct until rediscovered in 2016 and now has a California Rare Plant Rank of 1B.1. In some treatments, Malacothamnus mendocinensis has been included within Malacothamnus fasciculatus or Malacothamnus hallii. Phylogenetic and morphological evidence, however, indicate that it is not closely related to these species and should be recognized as a separate species.
Malacothamnus hallii is a species of flowering plant in the mallow family known by the common name Hall's bushmallow. It is endemic to southeastern counties of the San Francisco Bay Area, where it is a rare species. It has a California Rare Plant Rank of 1B.2. Malacothamnus hallii is occasionally treated within Malacothamnus fasciculatus.
Malacothamnus orbiculatus is a species of flowering plant in the mallow family known by the common names Tehachapi bushmallow and round-leaved bushmallow. It occurs in California, where it is common after burns on the desert-facing slopes of mountains, and Arizona, where it is currently only known from a few locations. Malacothamnus orbiculatus is occasionally treated within Malacothamnus fremontii.
Malacothamnus helleri is a species of flowering plant in the mallow family known by the common name Heller's bushmallow. It is endemic to Northern California, where it is a rare species. It has a California Rare Plant Rank of 3.3. Malacothamnus hellerii is occasionally treated within Malacothamnus fremontii.
Silphium perplexumJ.R.Allison is a prairie species in the Asteraceae endemic to the state of Alabama. S. perplexum is commonly known as Old Cahaba rosinweed, a reference to the Cahaba River near which all populations of this species are found.
Gambelia juncea is a species of flowering shrub in the plantain family commonly known as the Baja California bush snapdragon or Baja bush snapdragon. Gambelia juncea is a highly variable woody perennial to 1 m (3.3 ft) characterized by long, arching, reed-like stems and showy, bright red, two-lipped tubular flowers. Native to the Baja California peninsula and coastal Sonora, this species is widespread in the region across numerous habitats and has several varieties. It was formerly placed in the primarily South American genus Galvezia, but taxonomic studies have supported the reclassification of the two North American species into Gambelia. This species, with a number of cultivars, is widely used as an ornamental shrub for xeriscaping, erosion control, native plant gardens, and wildlife gardens.
Malacothamnus astrotentaculatus is a species of flowering plant in the mallow family known by the common name starry-tentacled bushmallow. It is named after the somewhat tentacle-like outgrowths on the calyx that are covered in stellate trichomes. It is endemic to Shasta and Tehama counties in California.
Malacothamnus eastwoodiae is a species of flowering plant in the mallow family known by the common name Alice’s lovely bushmallow. It is named after the botanist Alice Eastwood. It is endemic to Santa Barbara County, California and currently only known from Vandenberg Space Force Base.
Malacothamnus discombobulatus is a species of flowering plant in the mallow family known by the common name discombobulating bushmallow. It is morphologically similar to Malacothamnus davidsonii and was treated within M. davidsonii in the past. Malacothamnus discombobulatus is named after the confusion sown from its morphological similarity to M. davidsonii. It is endemic to Monterey and San Luis Obispo counties in California.
