Dracaena Ellenbeckiana
''Dracaena ellenbeckiana'' is a species of plant belonging to the Asparagaceae family, subfamily Nolinoideae Nolinoideae is a monocot subfamily of the family Asparagaceae in the APG III system of 2009. It used to be treated as a separate family, Ruscaceae s.l. The family name is derived from the generic name of the type genus, ''Nolina''. The subfamil ..., and is part of the dracaenoid clade along with closely related genera '' Sansevieria'' and '' Pleomele''. ''Dracaena ellenbeckiana'' is native to Ethiopia, Kenya, Somalia, Sudan, and Uganda, and primarily grows in the seasonally dry tropical biome. Taxonomy and morphology ''Dracaena ellenbeckiana'' was first described by Engl. in 1902. The species is a shrub or tree, growing 2-8 meters high, with erect stems that are often several from a common base, less often solitary, and little-branched. The stems can be up to in diameter and are longitudinally fissured. The leaves of '' Dracaena'' species are isobilateral and amphisto ...

Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on alpha taxonomy, plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl Anton Eugen Prantl, Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many Herbarium, herbaria and is followed by writers of many manuals and Flora (plants), floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He ...

Asparagaceae
Asparagaceae, known as the asparagus family, is a family of flowering plants, placed in the order Asparagales of the monocots. The family name is based on the edible garden asparagus, '' Asparagus officinalis''. Those who live in the temperate climates may be surprised to learn that this family includes both common garden plants as well as common houseplants. The garden plants include asparagus, yucca, bluebell, and hosta, and the houseplants include snake plant, corn cane, spider plant and plumosus fern. Taxonomy In earlier classification systems, the species involved were often treated as belonging to the family Liliaceae. The APG II system of 2003 allowed two options as to the circumscription of the family: either Asparagaceae ''sensu lato'' ("in the wider sense") combining seven previously recognized families, or Asparagaceae ''sensu stricto'' ("in the strict sense") consisting of very few genera (notably '' Asparagus'', also '' Hemiphylacus''), but nevertheless to ...

Nolinoideae
Nolinoideae is a monocot subfamily of the family Asparagaceae in the APG III system of 2009. It used to be treated as a separate family, Ruscaceae s.l. The family name is derived from the generic name of the type genus, ''Nolina''. The subfamily includes genera that had been placed in a range of different families, including Ruscaceae s.s., Nolinaceae, Dracaenaceae, Convallariaceae and Eriospermaceae. Like many groups of lilioid monocots, the genera included here were once included in a wide interpretation of the family Liliaceae The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. Plants in this family have evolved with a fair .... Genera A possibly incomplete list of the genera included in the Nolinoideae is given below. The reference is to the source which places the genus in this subfamily.

Sansevieria
''Sansevieria'' is a historically recognized genus of flowering plants, native to Africa, notably Madagascar, and southern Asia, now included in the genus '' Dracaena'' on the basis of molecular phylogenetic studies. Common names for the 70 or so species formerly placed in the genus include mother-in-law's tongue, devil's tongue, jinn's tongue, bow string hemp, snake plant and snake tongue. In the APG III classification system, ''Dracaena'' is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). It has also been placed in the former family Dracaenaceae. Description There is great variation within the species formerly placed in the genus; they range from succulent desert plants such as '' Dracaena pinguicula'' to thinner leafed tropical plants such as '' Dracaena trifasciata''. Plants often form dense clumps from a spreading rhizome or stolons. Foliage The leaves of former ''Sansevieria'' species are typically arranged in a rosette around ...

Pleomele
Pleomele is used a common name for several cultivated ornamental plants and may refer to: * Species of ''Pleomele'' (genus), a former plant genus in the family Ruscaceae now included in '' Dracaena'' * '' Dracaena reflexa'' (pleomele), a widely cultivated plant previously classified in the genus ''Pleomele'' {{Plant common name ...

Dracaena (plant)
''Dracaena'' () is a genus of about 120 species of trees and succulent shrubs. The formerly accepted genera '' Pleomele'' and '' Sansevieria'' are now included in ''Dracaena''. In the APG IV classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). It has also formerly been separated (sometimes with ''Cordyline'') into the family Dracaenaceae or placed in the Agavaceae (now Agavoideae). The name ''dracaena'' is derived from the romanized form of the Ancient Greek – ''drakaina'', "female dragon". The majority of the species are native to Africa, southern Asia through to northern Australia, with two species in tropical Central America. Description Species of ''Dracaena'' have a secondary thickening meristem in their trunk, termed Dracaenoid thickening by some authors, which is quite different from the thickening meristem found in dicotyledonous plants. This characteristic is shared with members of the Agavo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1902
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the abi ...

Taxa Named By Adolf Engler
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of East Tropical Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurma ...
