List of Salvia species

Salvia is the largest genus of plants in the mint family, Lamiaceae, with nearly 1000 species of shrubs, herbaceous perennials, and annuals.
 Within the Lamiaceae, "Salvia" is part of the tribe Mentheae within the subfamily Nepetoideae.
 It is one of several genera commonly referred to as sage, It includes the widely produced herb used in cooking, "Salvia officinalis" (common sage, or just "sage").
Salvia merjamie is a herbaceous perennial plant that is native to the east African highlands from Ethiopia to Tanzania, and also across the Red Sea in Yemen.
 It grows between 6,000 and 13,000 feet elevation in grasslands, forest edges, rocky outcrops, basalt slopes, and fallow fields.
 The specific epithet "merjamie" is derived from "meryamiye", the Arabian common name for the plant, which is shared with other local "Salvia" species such as "Salvia lanigera".
 The Maasai common name for "S. merjamie" is "Naingungundeu", meaning that the plant smells of rats, though the variety that is common in horticulture is named 'Mint Sauce' and is described as having a strong minty aroma.
 "S. merjamie" shares a similar distribution with "Salvia nilotica", though they are not known to hybridize.
Salvia blancoana is a prostrate perennial that is native to Spain and northwest Africa.
 It has narrow blue-green leaves and pale violet-blue flowers.
 Due to its being highly variable in the wild, and because of similarities to "Salvia candelabrum" and "Salvia lavandulifolia", it has often been confused with those two.
 Current opinion gives "S. blancoana" distinct species status, even while some botanists consider it a subspecies of its two close relatives.
 It differs from "S. lavandulifolia" and "S. candelabrum" in being prostrate, as opposed to merely low-growing.
 It also has whorls of 2-6, compared to 6-9 in "S. lavandulifolia".
Salvia" × "superba is a widely grown "Salvia" hybrid.
 Its origins are unknown, though it first appeared in cultivation, and its parents are believed to include "Salvia" × "sylvestris" and "Salvia amplexicaulis". "
Salvia nemorosa" has also been suggested as a direct parent or close relative, but with so many similarities between these species and hybrids, there is no conclusive evidence.
 It is often mistakenly called "Salvia superba".
Salvia 'Jean's Purple Passion' is a "Salvia" cultivar discovered at Cabrillo College in Aptos, California.
 It was found growing between "Salvia gesneriflora" 'Tequila' and "Salvia mexicana", who are presumed to be its parents.
 It is named for Jean Coria, a gardening enthusiast who propagated many species in the genus Salvia for many years at Strybing Arboretum.
Diplazium is a genus of ferns that specifically includes the approximately 400 known species of twinsorus ferns.
 The Greek root is "diplazein" meaning "double": the indusia in this genus lie on both sides of the vein.
 These ferns were earlier considered part of either the Athyriaceae, Dryopteridaceae, Aspleniaceae, or Polypodiaceae families but are often recognized as belonging to their own taxonomic family.
 The taxonomy of the genus is difficult and poorly known, and by 2009 has never been the subject of a complete monographic study.
 Their distribution is pantropical, with a few species extending into temperate areas.
Salvia koyamae (Shinano-akigiri) is a perennial rarely found in the wild and native to the Japanese island of Honshu, where it has a close affinity to two other "salvia" species: "Salvia glabrescens" and "Salvia nipponica".
 It was named by Tomitaro Makino, considered the "father of Japanese botany".
Pohole, also known as hō'i'o is an edible fiddlehead fern eaten in Hawaiian cuisine salad.
 The salads are made the unfurled fronds of a Diplazium esculentum fern (also known as Athyrium esculentum).
 The ferns grow in wet areas of shady valleys.
 The fern species Diplazium esculentum is believed to have been introduced and naturalized in Hawaii and was first reported collected in 1910.
 The fern also has medicinal uses.
Salvia freyniana is a critically endangered perennial plant that is endemic to Turkey, growing in sandy soil at 900 to elevation.
 It was first collected in 1890, described in 1892 by Joseph Friedrich Nicolaus Bornmüller and not discovered again until 2006.
 During field trips as part of a revision and study of "Salvia" species in Turkey, an unusual population of "Salvia" was discovered which was eventually shown to be the plant described by Bornmueller.
 It was the first collection of the plant since the original specimens in 1890.
Salvia is the largest genus of plants in the family Lamiaceae, with the number of species estimated to range from 700 to nearly 1,000.
 Members include shrubs, herbaceous perennials, and annuals.
 There are three main regions of radiation of "Salvia": Central and South America, with approximately 500 species; central Asia and the Mediterranean with approx. 250 species; eastern Asia with approximately 90 species.
