Primulina
''Primulina'' is a genus of flowering plants in the African violet family Gesneriaceae. It includes 232 species native to southern and north-central China and northern Vietnam. The species are mostly calciphilous, and typically grow in the extensive limestone karst regions of China and Vietnam.Luu HT, Hsieh C-L, Chuang C-R, Chen C- W, Tran NT, Vu NL, et al.

Gesneriaceae
Gesneriaceae, the gesneriad family, is a family (biology), family of flowering plants consisting of about 152 genera and ca. 3,540 species in the tropics and subtropics of the Old World (almost all Didymocarpoideae) and the New World (most Gesnerioideae), with a very small number extending to temperate areas. Many species have colorful and showy flowers and are cultivated as ornamental plants. Etymology The family name is based on the genus ''Gesneria'', which honours Switzerland, Swiss naturalist and humanism, humanist Conrad Gessner. Description Most species are herbaceous plant, herbaceous perennial plant, perennials or subshrubs but a few are woody shrubs or small trees. The phyllotaxy is usually opposite and decussate, but leaves have a spiral or alternate arrangement in some groups. As with other members of the Lamiales the flowers have a (usually) zygomorphic corolla whose petals are fused into a tube and there is no one character that separates a gesneriad from any o ...

Didymocarpoideae
The Didymocarpoideae are a subfamily of plants in the family Gesneriaceae. It was formerly the subfamily Cyrtandroideae. This subfamily consists mostly of Tropics, tropical and Subtropics, subtropical Old World genera, found in Africa, Asia and the Pacific. One species (''Rhynchoglossum azureum'') is native to Central and South America. Description Didymocarpoideae is one of two main subfamilies in the Gesneriaceae, the other being Gesnerioideae. (The third subfamily, Sanangoideae, contains only the genus ''Sanango''.) Didymocarpoideae seedlings usually have cotyledons which become different in size and shape (anisocotylous). One cotyledon ceases to grow at some point and then withers away. The other continues to grow, and in extreme cases may grow to become very large and be the only leaf on the plant (''Monophyllaea'', some ''Streptocarpus''). Didymocarpoideae flowers usually have two fertile stamens, less often four and rarely one or five. The Ovary (botany), ovary is always ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or bec ...

Calciphilous
A calcicole, calciphyte or calciphile is a plant that thrives in lime rich soil. The word is derived from the Latin 'to dwell on chalk'. Under acidic conditions, aluminium becomes more soluble and phosphate less. As a consequence, calcicoles grown on acidic soils often develop the symptoms of aluminium toxicity, i.e. necrosis, and phosphate deficiency, i.e. anthocyanosis (reddening of the leaves) and stunting. A plant that thrives in acid soils is known as a calcifuge. A plant thriving on sand (which may be acidic or calcic) is termed psammophilic or arenaceous (see also arenite). Examples of calcicole plants * Ash trees (''Fraxinus'' spp.) * Honeysuckle (''Lonicera'') * ''Buddleja'' * Lilac (''Syringa'') * Beet * ''Clematis'' * ''Sanguisorba minor'' * Some European orchids * Some succulent plants genera '' Sansevieria'' and ''Titanopsis'' or cacti A cactus (: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae (), a family of the order ...
