Stromanthe is a genus of plant in family Marantaceae, native to the tropical portions of the Americas from Mexico to Trinidad to northern Argentina.
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").
Nematinae is a subfamily of sawflies belonging to the family Tenthredinidae.
 It contains over 1000 described species.
 Members of this subfamily feed on a wide range of plants (over 20 different plant families have been recorded as hosts) and employ a wide range of feeding habits, both internally and externally, on their host plants.
The University of Oxford Botanic Garden is the oldest botanic garden in Great Britain and one of the oldest scientific gardens in the world.
 The garden was founded in 1621 as a physic garden growing plants for medicinal research.
 Today it contains over 8,000 different plant species on 1.8 ha .
 It is one of the most diverse yet compact collections of plants in the world and includes representatives from over 90% of the higher plant families.
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 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.
Lophodermium is a genus of fungi within the family Rhytismataceae.
 The genus contains 145 species and has a global distribution.
 Species of this genus are usually observed producing zone lines, conidiomata and ascomata on dead fallen leaves, but at least some are known to colonize living leaves.
 In many cases they then live inside the colonized leaf as a symptomless endobiont, where they are regarded as detritivores utilising dead plant matter.
 In a few cases they may kill all or part of the leaf prematurely, and there is a substantial literature dealing with those species as plant pathogens.
 The genus infects many different plant families but with a notable concentration in the family Pinaceae; many "Lophodermium" species are restricted to a single host genus (or even species), but some, particularly those infecting grasses, may infect several genera.
 Some are economically important plant pathogens, such as those that cause needlecast disease in European Black Pine, Scots Pine and Red Pine in forestry and christmas tree plantations.
 In these species, notably "L. pinastri" and "L. seditiosum", the fungal spores disperse and infect the pine needles in late summer, which turn brown by the following spring and then fall off.
Dendrology (Ancient Greek: δένδρον , "dendron", "tree"; and Ancient Greek: -λογία , "-logia", "science of" or "study of") or xylology (Ancient Greek: ξύλον , "ksulon", "wood") is the science and study of wooded plants (trees, shrubs, and lianas), specifically, their taxonomic classifications.
 There is no sharp boundary between plant taxonomy and dendrology; however, woody plants not only belong to many different plant families, but these families may be made up of both woody and non-woody members.
 Some families include only a few woody species.
 Dendrology, as a discipline of industrial forestry, tends to focus on identification of economically useful woody plants and their taxonomic interrelationships.
 As an academic course of study, Dendrology will include all woody plants, native and non-native, that occur in a region.
 A related discipline is the study of Sylvics, which focuses on the autecology of genera and species.
The World Checklist of Selected Plant Families (usually abbreviated to WCSP) is an "international collaborative programme that provides the latest peer reviewed and published opinions on the accepted scientific names and synonyms of selected plant families."
 Maintained by the Royal Botanic Gardens, Kew, it is available online, allowing searches for the names of families, genera and species, as well as the ability to create checklists.
A cushion plant is a compact, low growing, mat forming plant that is found in alpine, subalpine, arctic, or subarctic environments around the world.
 The term "cushion" is usually applied to woody plants that grow as spreading mats, are limited in height above the ground (a few inches at most), have relatively large and deep tap roots, and have life histories adapted to slow growth in a nutrient poor environment with delayed reproductivity and reproductive cycle adaptations.
 The plant form is an example of parallel or convergent evolution with species from many different plant families on different continents converging on the same evolutionary adaptations to endure the harsh environmental conditions.
