Celastrus Kusanoi
''Celastrus'', commonly known as staff vine, staff tree or bittersweet, is the type genus of the family Celastraceae; it contains over 40 species of shrubs and vines, which have a wide distribution in East Asia, Australasia, Africa, and the Americas. Description The leaves are alternate and simple, ovoid, and typically long. The flowers are small, white, pink or greenish, and borne in long panicles; the fruit is a three-valved berry. In North America, they are known as bittersweet, presumably a result of confusion with the unrelated bittersweet (''Solanum dulcamara'') by early colonists. '' C. orbiculatus'' is a serious invasive weed in much of eastern North America. Species ''Plants of the World Online''Plants of the World Online ''Celastrus'' L.

Vine Staff
__NOTOC__ The vine staff, vine-staff, or centurion's staff () was a vinewood rod of about in length used in the ancient Roman army and navy. It was the mark and tool of the centurion: both as an implement in the direction of drill and maneuvers; and to beat wayward or laggard soldiers or sailors under his command. It was also borne by '' evocati'' who held an equivalent rank. Origin The vine staff may have derived from the Etruscan ''lituus'' and was certainly in use by the Punic Wars. Following the enactment of the Porcian Laws in the early 2nd century BC, it was the only manner by which Roman citizens could be beaten and is mentioned by various classical authors. A line in Ovid notes that "the good general commits the ''vitis'' to one to command one hundred." Pliny: "The centurion's vine staff is an excellent medicine for sluggish troops who don't want to advance..." "and when used to chastise offenses makes even the punishment respectable." It carried none of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berry (botany)
In botany, a berry is a fleshy fruit without a drupe, drupe (pit) produced from a single flower containing one Ovary (botany), ovary. Berries so defined include grapes, Ribes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines), persimmons and bananas, but exclude certain fruits that meet the berry, culinary definition of berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more gynoecium, carpels from the same flower (i.e. from a simple or a compound ovary). The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as ''Capsicum'' species, with air rather than pulp around their seeds. Many berries are edible, but others, such as the Potato fruit, fruits of the potato and the deadly nightshade, are poisonous to humans. A plant that be ...

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 ...

Weed
A weed is a plant considered undesirable in a particular situation, growing where it conflicts with human preferences, needs, or goals.Harlan, J. R., & deWet, J. M. (1965). Some thoughts about weeds. ''Economic botany'', ''19''(1), 16-24. Plants with characteristics that make them hazardous, aesthetically unappealing, difficult to control in managed environments, or otherwise unwanted in agriculture, farm land, Orchard, orchards, gardens, lawns, Park, parks, recreational spaces, residential and industrial areas, may all be considered weeds.Holzner, W., & Numata, M. (Eds.). (2013). ''Biology and ecology of weeds'' (Vol. 2). Springer Science & Business Media. The concept of weeds is particularly significant in agriculture, where the presence of weeds in fields used to grow crops may cause major losses in yields. Invasive species, plants introduced to an environment where their presence negatively impacts the overall functioning and biodiversity of the ecosystem, may also sometime ...
