Adenostoma is a genus of shrubs in the Rose family (Rosaceae) containing only two species, chamise ( Adenostoma fasciculatum ) and redshanks ( Adenostoma sparsifolium ). Both are native to the Californias.
The plants grow in a habit of shrubs to small trees, and the stem is more or less resinous. [1] Both species in this genus feature stiff, linear leaves arranged alternately or in clusters along stems with shredding bark. Flowers form on a panicle, are cream to white and, as in all members of the rose family, have hypanthia. [2] The fruit is an achene. Chromosome number is 2n = 18. [1]
Both species are native to coastal California and Baja California. Adenostoma fasciculatum is also native to California in the Sierra Nevada. [2] They are found in plant communities and sub-ecoregions of the California chaparral and woodlands ecoregion.
Phylogenetic analysis places Adenostoma closest to Chamaebatiaria and Sorbaria , and suggests tentative placement in the subfamily Spiraeoideae, tribe Sorbarieae. [3] The name Adenostoma comes from Greek, meaning "glandular mouth," referring to the hypanthium ring gland. [1]
Chaparral is a shrubland plant community found primarily in California, in southern Oregon and in the northern portion of the Baja California Peninsula in Mexico. It is shaped by a Mediterranean climate and infrequent, high-intensity crown fires.
Adenostoma fasciculatum, commonly known as chamise or greasewood, is a flowering plant native to California and Baja California. This shrub is one of the most widespread plants of the California chaparral ecoregion. Chamise produces a specialized lignotuber underground and at the base of the stem, known as a burl, that allow it to resprout after fire has off burned its stems. It is noted for its greasy, resinous foliage, and its status as one of California's most iconic chaparral shrubs.
Euphorbia albomarginata, whitemargin sandmat or rattlesnake weed, is a small low-growing perennial, in the spurge family native to desert, chaparral, and grassland habitats of southwestern North America, from southern and central California to Northern Mexico and Louisiana.
Baccharis pilularis, called coyote brush, chaparral broom, and bush baccharis, is a shrub in the family Asteraceae native to California, Oregon, Washington, and Baja California. There are reports of isolated populations in New Mexico, most likely introduced.
Eriogonum fasciculatum is a species of wild buckwheat known by the common names California buckwheat and flat-topped buckwheat. Characterized by small, white and pink flower clusters that give off a cottony effect, this species grows variably from a patchy mat to a wide shrub, with the flowers turning a rusty color after blooming. This plant is of great benefit across its various habitats, providing an important food resource for a diversity of insect and mammal species. It also provides numerous ecosystem services for humans, including erosion control, post-fire mitigation, increases in crop yields when planted in hedgerows, and high habitat restoration value.
Adenostoma sparsifolium, commonly known as redshanks or less commonly, ribbonwood or ribbon bush, is a multi-trunked tree or shrub native to dry slopes or chaparral of Southern California and northern Baja California.
Quercus durata, commonly known as leather oak, is a species of oak endemic to California, common in the Coast Ranges and the foothills of the Sierra Nevada. The common name "leather oak" is derived from the leathery texture on the lop of its leaves. Taxonomically it is placed in the white oak group.
Hooveria purpurea is a species of flowering plant related to the agaves known by the common name purple amole. This species of soap plant is endemic to California, where it grows in the Santa Lucia Range, in the Central Coast region. There are two varieties of this plant, and both are believed to be quite rare. It is a federally listed threatened species.
Chamisa may refer to:
Arctostaphylos montaraensis, known by the common name Montara manzanita, is a species of manzanita in the family Ericaceae.
Ceanothus verrucosus is a species of shrub in the family Rhamnaceae known by the common names wart-stem ceanothus, barranca brush, coast lilac and white coast ceanothus. It is endemic to northwestern Baja California and San Diego County, where it grows in coastal sage scrub and coastal succulent scrub habitats. It is considered a rare species north of the international border, as most of the valuable coastal land that hosts this plant in the San Diego area has been claimed for development. In California, several extant populations still remain scattered around the region, such as one protected at Torrey Pines.
Dudleya variegata is a deciduous succulent plant in the family Crassulaceae known by the common names variegated liveforever, variegated dudleya or rarely San Diego Hasseanthus. A cryptic plant that survives part of the year dormant underground from starch reserves in a corm, after sufficient rainfall, leaves will emerge, soon giving way to small inflorescences with yellow star-shaped flowers. It is native to Baja California and adjacent San Diego County in California, where it grows in several habitat types, including chaparral and vernal pools.
Pine Hill Ecological Reserve is a nature reserve of 403 acres (1.63 km2) located due east of Folsom Lake in the Sierra Nevada foothills, in El Dorado County, California. The reserve was established in 1979, and is managed by the Bureau of Land Management.
The California coastal sage and chaparral is a Mediterranean forests, woodlands, and scrub ecoregion located in southwestern California and northwestern Baja California (Mexico). It is part of the larger California chaparral and woodlands ecoregion.
Thermopsis macrophylla is a species of flowering plant in the legume family known by the common names Santa Inez goldenbanner and Santa Ynez false-lupine.
Deinandra fasciculata, known by the common names clustered tarweed and fascicled spikeweed, is a species of flowering plant in the family Asteraceae native to western North America.
Greasewood is a common name shared by several plants:
Fraxinus parryi, known by common names chaparral ash, crucecilla, and fresnillo, is a species of ash native to southwestern North America, growing as a shrub or a small tree.
