Underground Tree
A geoxyle is a plant in which an enlarged, woody structure occurs beneath the surface of the ground. Such plants have developed independently in various plant lineages, mostly evolving in the Pliocene and subsequently diverging within the last two million years. In contrast to their close relatives, these plants have developed in areas with both high rainfall and a high frequency of fires. They are sometimes known as underground trees, and the areas where they grow as underground forests. The geoxylic growth forms of woody subshrubs is characterised by massive lignotubers or underground woody Glossary of botanical terms#axis, axes from which emerge aerial shoots which may be ephemeral. These growth forms are found in savannahs in southern Africa. It is thought they developed in tandem with the spread of savannahs which resulted in an increase in tall grasses which are easily flammable during the long dry season associated with the savannah climate. Some well-known examples of geoxyle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Elephantorrhiza Elephantina
''Entada elephantina'', commonly known as the eland's wattle or elephant's root, is a subshrub in the mimosoid clade of legumes. They occur widely and in several bioregions of southern Africa in Namibia, Botswana, Zimbabwe, Mozambique, South Africa, Eswatini, and Lesotho. Considerable size variation has been noted, and polyploidy was suspected. Description They have a suffrutescent habit typical of their genus. They produce unbranched and unarmed aerial stems of less than a metre tall. The various populations show considerable variation in terms of the number of pinnae pairs and the number, size and shape of the leaflets. They flower from September to November and are pollinated mainly by the African honeybee. The flowering racemes are typically confined to the lower part of the stem, so that the pods are usually suspended just above ground level, or alternatively rest inconspicuously on the ground. Similar species ''Entada burkei'' has similar aerial parts, but its seeds are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salacia Kraussii
In ancient Roman mythology, Salacia ( , ) was the female divinity of the sea, worshipped as the goddess of salt water who presided over the depths of the ocean. Neptune was her consort. That Salacia was the consort of Neptune is implied by Varro, and is positively affirmed by Seneca, Augustine and Servius. She is identified with the Greek goddess Amphitrite, consort of Poseidon, or Tethys who was also a marine deity. The god Neptune wanted to marry Salacia, but she was in great awe of her distinguished suitor, and to preserve her virginity, with grace and celerity she managed to glide out of his sight, and hid from him in the Atlantic Ocean. The grieving Neptune sent a dolphin to look for her and persuade the fair nymph to return and share his throne. Salacia agreed to marry Neptune and the King of the Deep was so overjoyed at these good tidings that the dolphin was awarded a place in the heavens, where he now forms a well known constellation Delphinus. Salacia is represente ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maytenus Nemorosa
''Gymnosporia nemorosa'' is a spiny, somewhat sprawling evergreen shrub or small tree with drooping branches growing to some 5 m tall and found along forest edges in Mpumalanga, Eswatini, KwaZulu-Natal south to the Garden Route in the Southern Cape. In Maputaland the species adopts the form of a geoxylic suffrutex or ‘underground’ tree, with shoots sprouting from its woody, underground axis. Its fragrant white, unisexual flower clusters grow in the axils of leaves on lateral shoots resembling spines. Dusky-pink, pear-shaped, pendulous fruits are about 15mm in length and the same in diameter, dehiscing along three longitudinal lines to produce 3 valves curling back from the distal end to reveal orange arils enclosing the seeds. Leaves are alternate or tufted, hairless, leathery, 25-50mm long, with slightly serrate margins, ovate to round in shape, glossy and dark green above, paler beneath, emarginate to acute, depressed apex. Branchlets are spiny and densely spotted with pale ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eugenia Albanensis
''Eugenia'' is a genus of flowering plants in the myrtle family Myrtaceae. It has a worldwide, although highly uneven, distribution in tropical and subtropical regions. The bulk of the approximately 1,100 species occur in the New World tropics, especially in the eastern Brazil's northern Andes, the Caribbean, and the Atlantic Forest (coastal forests). Other centers of diversity include New Caledonia and Madagascar. Many species in the Old World have received a new classification into the genus ''Syzygium''. All species are woody evergreen trees and shrubs. Several are grown as ornamental plants for their attractive glossy foliage, and a few produce edible fruit that are eaten fresh or used in jams and jellies. Taxonomy The genus was named in honor of Prince Eugene of Savoy. Many species new to science have been and are in the process of being described from these regions. For example, 37 new species of ''Eugenia'' have been described from Mesoamerica in the past few years. At ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diospyros Galpinii
''Diospyros'' is a genus of over 700 species of deciduous and evergreen trees and shrubs. The majority are native to the tropics, with only a few species extending into temperate regions. Individual species valued for their hard, heavy, dark timber, are commonly known as ebony trees, while others are valued for their fruit and known as persimmon trees. Some are useful as ornamentals and many are of local ecological importance. Species of this genus are generally dioecious, with separate male and female plants. Taxonomy and etymology The generic name ''Diospyros'' comes from a Latin name for the Caucasian persimmon ('' D. lotus''), derived from the Greek διόσπυρος : dióspyros, from ''diós'' () and ''pyrós'' (). The Greek name literally means "Zeus's wheat" but more generally intends "divine food" or "divine fruit". The genus is a large one and the number of species has been estimated variously, depending on the date of the source. The Royal Botanic Gardens, Kew, list ...
