Acanthogilia is a genus with a single species of desert shrub from Baja California, Mexico. It was first scientifically described as a genus in 1986. [1] [2]
Its closest relatives within the family Polemoniaceae are not clear. Some evidence suggests it was first to diverge from the ancestral member of that family, some puts it in a group with Bonplandia , Cobaea , and Cantua , and some say that those three genera diverged first, followed by Acanthogilia (followed by the rest of the family).

The Baja California peninsula is a peninsula in northwestern Mexico. It separates the Gulf of California from the Pacific Ocean. The peninsula extends from Mexicali, Baja California, in the north to Cabo San Lucas, Baja California Sur, in the south.
Baja California, officially Estado Libre y Soberano de Baja California, is a state in Mexico. It is the northernmost and westernmost of the 32 federal entities of Mexico. Before becoming a state in 1952, the area was known as the North Territory of Baja California. It has an area of 70,113 km2 (27,071 sq mi) and comprises the northern half of the Baja California Peninsula, north of the 28th parallel, plus oceanic Guadalupe Island. The mainland portion of the state is bordered on the west by the Pacific Ocean; on the east by Sonora, the U.S. state of Arizona, and the Gulf of California; on the north by the U.S. state of California; and on the south by Baja California Sur.
Nolina is a genus of tropical xerophytic flowering plants, with the principal distribution being in Mexico and extending into the southern United States. They are large, dioecious plants.
Calochortus is a genus of flowering plants in the lily family. The group includes herbaceous, perennial and bulbous species, all native to North America.
The Polemoniaceae are a family of flowering plants consisting of about 25 genera with 270–400 species of annuals and perennials native to the Northern Hemisphere and South America, with the center of diversity in western North America.
Gambel's quail is a small ground-dwelling bird in the New World quail family. It inhabits the desert regions of Arizona, California, Colorado, New Mexico, Nevada, Utah, Texas, and Sonora; also New Mexico-border Chihuahua and the Colorado River region of Baja California. Gambel's quail is named in honor of William Gambel, a 19th-century naturalist and explorer of the Southwestern United States.
Garrya is a genus of flowering plants in the family Garryaceae native to Mexico, the western United States, Central America and the Greater Antilles. Common names include silk tassel and tassel bush.
The Antilocapridae are a family of artiodactyls endemic to North America. Their closest extant relatives are the giraffids. Only one species, the pronghorn, is living today; all other members of the family are extinct. The living pronghorn is a small ruminant mammal resembling an antelope.
Ipomopsis is a genus of flowering plants in the phlox family, Polemoniaceae. The annual and perennial herbs it contains are native to the Americas, particularly North America.
Collomia is a genus of flowering plants in the family Polemoniaceae. Species in the genus are known generally as trumpets, mountain trumpets, or trumpet flowers. They are native to North America and southern South America. The genus name comes from the Greek kolla ("glue"), a reference to the seeds, which become gelatinous in texture when wet.
The mountain quail is a small ground-dwelling bird in the New World quail family. This species is the only one in the genus Oreortyx, which is sometimes included in Callipepla. This is not appropriate, however, as the mountain quail's ancestors diverged from other New World quails earlier than the bobwhites, no later than 6 mya.
The Espíritu Santo antelope squirrel is a species of antelope squirrel in the family Sciuridae. It is endemic to Mexico, where it is known only from the island of Espíritu Santo in the Gulf of California. The species was originally described by Edward William Nelson and Edward Alphonso Goldman in 1909 as a subspecies of the white-tailed antelope squirrel, a wide-ranging species in the southwestern U.S. and Mexico. In 1938, Arthur H. Howell elevated the subspecies to full species status, on the basis of slightly larger skull proportions and the absence or reduction of the third upper premolar. Studies of DNA and chromosomes have variously suggested close relationships with Harris's antelope squirrels or other subspecies of white-tailed antelope squirrel. A 2007 comparison of DNA and morphological traits suggested the differences between Espíritu Santo squirrels and those on the Baja California peninsula and other islands were not enough to warrant distinct species but rather a subspecies of white-tailed antelope squirrels. Since 2008 the IUCN has similarly recognized the Espíritu Santo antelope squirrel as a subspecies of white-tailed antelope squirrel.
The Madrean Region is a floristic region within the Holarctic Kingdom in North America, as delineated by Armen Takhtajan and Robert F. Thorne. It occupies arid or semiarid areas in the southwestern United States and northwestern Mexico and is bordered by the Rocky Mountain Floristic Region and North American Atlantic Region of the Holarctic Kingdom in the north and in the east, Caribbean Region of the Neotropical Kingdom in the south.
Hazardia is a small genus of North American flowering plants in the family Asteraceae. Plants in this genus may be called bristleweeds or goldenbushes.
Oryzomys peninsulae, also known as the Lower California rice rat, is a species of rodent from western Mexico. Restricted to the southern tip of the Baja California peninsula, it is a member of the genus Oryzomys of family Cricetidae. Only about twenty individuals, collected around 1900, are known, and subsequent destruction of its riverine habitat may have driven the species to extinction.
Tritonicula myrakeenae is a species of dendronotid nudibranch. It is a marine gastropod mollusc in the family Tritoniidae. A number of species of Tritonia were moved to a new genus Tritonicula in 2020 as a result of an integrative taxonomic study of the family Tritoniidae.
El Vallecito is an archaeological site located in the city of La Rumorosa, in the Tecate Municipality, Baja California, Mexico.
Saltugilia is a genus of flowering plants in the phlox family, Polemoniaceae. They are known commonly as woodland gilias. There are four species. Two are endemic to California in the United States, and the distributions of the other two extend into Baja California in Mexico.
Margaret R. Wood Bancroft, was an American naturalist and explorer of Baja California. She was also a social leader.
Capromeryx was a genus of dwarf pronghorns (Antilocapridae) that originated in North America during the Pliocene about 5 million years ago. The closest living relative and only surviving member of the family is the North American pronghorn.
