Sauropus Dunlopii
The genus ''Sauropus'', of the family Phyllanthaceae, comprises about 40 species of herbs, shrubs or subshrubs, sometimes with woody bases. These plants can be monoecious or dioecious. They are distributed in Southeast Asia, Malesia and Australia. Taxonomy In a 2006 revision of the Phyllanthaceae, it was recommended that ''Sauropus'' be subsumed in ''Phyllanthus''; however, new combinations in ''Phyllanthus'' for former ''Sauropus'' species remain to be published. Description ''Sauropus'' species have alternate, entire leaves with short petioles and small stipules. Flowers appear at axils and mainly form clusters. There are 6 perianth segments divided in 2 whorls, with female flowers often having bigger perianths. At male flowers, the perianth is tube-like, with 3 stamen. The fruit is berry-like, ovoid or globose, and fleshy. Species include *'' Sauropus albiflorus'' *'' Sauropus amabilis'' *'' Sauropus amoebiflorous'' *''Sauropus androgynus'' - star gooseberry, katuk *'' Saur ...

Dioecious
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sauropus Assimilis
''Sauropus assimilis'' is an extremely rare species of plant in the family Phyllanthaceae. It is a tree growing in wet evergreen forests in lowlands. Endemic to southwestern Sri Lanka, and only known from the Sinharaja Biosphere Reserve there, evidence of its existence was last catalogued before 1991 (in a survey held between 1991 and 1996 by the National Conservation Review of Sri Lanka), and it has not been found since then. It may since have become extinct. ''Sauropus assimilis'' was first collected for scientific examination and classification from Allagalla, in the Central Province of Sri Lanka, at an elevation of 3000 feet, by botanist George Henry Kendrick Thwaites. This high elevation, when compared with where it has been found more recently, would seem to indicate that the historic range of ''S. assimilis'' is much broader than it stands today. Thwaites described and published this species for the first time in 1861. The specific epithet "''assimilis''" is Latin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sauropus Androgynus
''Sauropus androgynus'', also known as katuk, star gooseberry, or sweet leaf, is a shrub grown in some tropical regions as a leaf vegetable. Its multiple upright stems can reach 2.5 meters high and bear dark green oval leaves 5–6 cm long. It is a good source of vitamin K. However, a study has suggested that excessive consumption of juiced Katuk leaves (due to its popularity for body weight control in Taiwan in the mid '90s) can cause lung damage, due to its high concentrations of the alkaloid papaverine. It also has high level of provitamin A carotenoids, especially in freshly picked leaves, as well as high levels of vitamins B and C, protein and minerals. The more the leaves mature, the higher the nutrient content of the leaves. It is common in evergreen forest and cultivated up to 1,300 m. Cultural usage It is one of the most popular leafy vegetables in South and Southeast Asia and is notable for high yields and palatability. Indonesia In Indonesia, the fl ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...

Stipule
In botany, a stipule is an outgrowth typically borne on both sides (sometimes on just one side) of the base of a leafstalk (the petiole). Stipules are considered part of the anatomy of the leaf of a typical flowering plant, although in many species they may be inconspicuous —or sometimes entirely absent, and the leaf is then termed ''exstipulate''. (In some older botanical writing, the term "stipule" was used more generally to refer to any small leaves or leaf-parts, notably prophylls.) The word ''stipule'' was coined by Linnaeus''Concise English Dictionary'' Wordsworth Editions Ltd. 1994, from Latin ''stipula'', straw, stalk. Types of stipules General characteristics The position of stipules on a plant varies widely from species to species, though they are often located near the base of a leaf. Stipules are most common on dicotyledons, where they appear in pairs alongside each leaf. Some monocotyledon plants display stipule-like structures, but only display one per leaf ...

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves with a petiole are said to be petiolate, while leaves lacking a petiole are called sessile or apetiolate. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk may be long, as in the leaves of celery and rhubarb, or short. When completely absent, the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile. In some other plant groups, such as the speedwell genus '' Veronica'', petiolate and sessile leaves may occur in different species. In the grasses (Poaceae), ...
