The Jepson Manual also follows Philip A. Munz and David D. Keck in their A California Flora and Supplement of 1958 and 1968. [2] Like other florae, The Jepson Manual builds upon these prior publications. Except for the number of line drawings, it has more in common with Munz's 1968 book than with Jepson's 1923 book.
It was founded by Willis Linn Jepson in 1950, and named after him. [7] The Jepson Herbarium supports the Jepson eFlora, a taxonomic database that builds on and expands the second edition of The Jepson Manual. It describes itself as "the foremost authority on the native and naturalized vascular plants of California". [8]
Of California's total plant population, 2,153 species, subspecies, and varieties are endemic and native to California alone, according to the 1993 Jepson Manual study. [4] This botanical diversity stems not only from the size of the state, but also its diverse topographies , climates, and soils (e.g. serpentine outcrops ).

As of April 2024, Plants of the World Online accepted the placement of M. villosa within M. odoratissima. [1] Older sources, such as the 2012 Jepson Manual, retain M. villosa as a separate species. [6]
Others treated it within Cupressus goveniana as either a variety (C. goveniana var. pigmaea Lemmon) [9] or a subspecies (C. goveniana subsp. pygmaea (Lemmon) A.Camus), including Camus (1914), [10] and the Jepson Manual (1993), [11] and one publication, the Flora of North America, did not distinguish it at all within C. goveniana.

The California Floristic Province is a world biodiversity hotspot as defined by Conservation International, due to an unusually high concentration of endemic plants: approximately 8,000 plant species in the geographic region, and over 3,400 taxa limited to the CFP proper, as well as having lost over 70% of its primary vegetation. A biodiversity ...
