Triodon (plant)
''Diodia'' (or buttonweed) is a genus of flowering plants in the Family (biology), family Rubiaceae. It was described by Carl Linnaeus in 1753. The genus is found from southern and eastern United States, South America, Central America, Mexico, the West Indies and tropical Africa. Other buttonweeds Many species of ''Diodia'' have been transferred to a closely related genus ''Diodella'', and therefore the name buttonweed also applies to these species. There are also many species of false buttonweeds in the related genus ''Spermacoce''. ''Abutilon theophrasti'' in the family Malvaceae is also known by the common name of buttonweed.

Diodia Virginiana
''Diodia virginiana'' is a plant species in the Rubiaceae, common name Virginia buttonweed. It is a spreading, matted perennial with opposite leaves, often mottled because of a virus that attacks the foliage. Flowers are white, cross-shaped with four petals. Fruits are green, often floating on water. The species can become a nuisance weed, hard to eradicate because of underground parts that remain behind when you try to pull up the plant. ''Diodia virginiana'' is native to Cuba, Nicaragua, Mexico, Connecticut, and the south-central and southeastern United States. It is known from every state on the Gulf Coast of the United States, Gulf and East Coast of the United States, Atlantic coasts from Texas to New Jersey as well as all the states in the Tennessee River Valley, Tennessee and Ohio River Valleys and the southern Great Plains. The species is also naturalized in Japan, Taiwan and northern California. Its habitats include edges of marshes, savanna margins, and low fields. Refe ...

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss people, Swiss botany, botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. De Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
