Malacothamnus eastwoodiae | |
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. [1] [2]
Malacothamnus eastwoodiae is distinguished from all other Malacothamnus taxa, excluding Malacothamnus densiflorus var. viscidus, by the combination of relatively long glandular trichomes and a spike-like inflorescence. Malacothamnus eastwoodiae is most easily distinguished from Malacothamnus densiflorus var. viscidus using geographic range. [1] [2]
Malvoideae is a botanical name at the rank of subfamily, which includes in the minimum the genus Malva. It was first used by Burnett in 1835, but was not much used until recently, where, within the framework of the APG System, which unites the families Malvaceae, Bombacaceae, Sterculiaceae and Tiliaceae of the Cronquist system, the aggregate family Malvaceae is divided into 9 subfamilies, including Malvoideae. The Malvoideae of Kubitzki and Bayer includes 4 tribes:
Alice Eastwood was a Canadian American botanist. She is credited with building the botanical collection at the California Academy of Sciences in San Francisco. She published over 310 scientific articles and authored 395 land plant species names, the fourth-highest number of such names authored by any female scientist. There are seventeen currently recognized species named for her, as well as the genera Eastwoodia and Aliciella.
Malacothamnus (bushmallow) is a genus of shrubs 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 and from a few disjunct locations in Arizona. 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.
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 densiflorus is a species of flowering plant in the mallow family, which has two varieties. It is endemic to the Peninsular Ranges of southwestern California and northwestern Baja California.
Malacothamnus fasciculatus is a species of flowering plant in the mallow family, which has four varieties. It is endemic to southwestern California and northwestern Baja California.
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.
Malveae is a tribe of flowering plants in the mallow family Malvaceae, subfamily Malvoideae. The tribe circumscribes approximately 70 genera and 1040 species and has the greatest species diversity out the three tribes that make up Malvoideae. The flowers of Malveae are five-merous with a characteristic staminal column, a trait found throughout Malvoideae. Although there are not many economically important species within Malveae, the tribe includes Althaea officinalis, otherwise known as the marsh-mallow.
Notholithocarpus densiflorus, commonly known as the tanoak or tanbark-oak, is a broadleaf tree in the family Fagaceae, and the type species of the genus Notholithocarpus. It is native to the far western United States, particularly Oregon and California. It ranges from 15–40 meters in height, with a trunk diameter of 60–190 centimeters.
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 lucianus is a species of flowering plant in the mallow family known by the common names Santa Lucia bushmallow and Arroyo Seco bushmallow and by the cultivar name Hanging Valley bushmallow. It is endemic to Monterey County, California, where it is known from the Santa Lucia Mountains.
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 parishii is a species of flowering plant in the mallow family known by the common name Parish's bushmallow. It is endemic to San Bernardino County, California, where it is confirmed from only a single collection from 1895. It has a California Rare Plant Rank of 1A. Malacothamnus parishii is currently treated as an extreme form of Malacothamnus fasciculatus var. laxiflorus. Phylogenetic analyses are needed to confirm whether it should be treated as a separate species or not.
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 but morphological, phylogenetic, and geographic evidence shows them to be distinct species, though there is a small zone of intergradation where their geographic ranges meet.
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 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.
Malacothamnus nuttallii is a species of flowering plant in the mallow family known by the common name Ojai bushmallow. It is named after the botanist Thomas Nuttall. It is endemic to Santa Barbara, San Luis Obispo, and Ventura counties in California. It is sometimes treated as a variety of Malacothamnus fasciculatus but morphological, phylogenetic, and phenological evidence show it to be distinct. Malacothamnus nuttallii is widely planted and is in cultivation under the name Malacothamnus fasciculatus ‘Casitas’.
Malacothamnus marrubioides is a species of flowering plant in the mallow family known by the common name Santa Clarita bushmallow. It is currently only known from Los Angeles and Ventura counties in California, though its purported type locality suggests it may have occurred further north under or near what is now Millerton Lake.
Malacothamnus foliosus is a species of flowering plant in the mallow family known by the common names Ensenada bushmallow and monarch bushmallow. It is endemic to Baja California, Mexico and has been introduced into Los Angeles County, California. Morphological and geographic evidence indicates that M. foliosus could possibly be treated as multiple taxa, but phylogenetic analyses are inconclusive and more research is needed.
