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 4 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. [1]

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 and Atlantic coasts from Texas to New Jersey as well as all the states in the Tennessee and Ohio River Valleys and the southern Great Plains. [2] The species is also naturalized in Japan, Taiwan and northern California. [3] [4]

<span class="mw-page-title-main">Calcareous glade</span> Type of ecological community found where bedrock occurs near the surface.

A calcareous glade is a type of ecological community that is found in the central Eastern United States. Calcareous glades occur where bedrock such as limestone occurs near or at the surface, and have very shallow and little soil development. Due to the shallow soil and the extreme conditions created by it, trees are often unable to grow in the glades. This creates a habitat that is usually sunny, dry, and hot. Calcareous glade vegetation is more similar to that of a desert habitat than a grassland, being dominated by small spring annuals with occasional geophytic or succulent perennials.
