The Amaryllidaceae are a family of herbaceous, mainly perennial and bulbous (rarely rhizomatous) flowering plants in the monocot order Asparagales. The family takes its name from the genus Amaryllis and is commonly known as the amaryllis family. The leaves are usually linear, and the flowers are usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae). The

The Crassulaceae (, from Latin crassus, thick), also known as the crassulas, the stonecrops or the orpine family, are a diverse family of flowering plants primarily characterized by succulent leaves and a form of photosynthesis known as crassulacean acid metabolism (CAM), in which plants photosynthesize in the daytime and exchange gases during the cooler temperatures of the night. The blossoms of crassulas generally have five floral parts. Crassulaceae are usually herbaceous, though there are some subshrubs, and relatively few trees or aquatic plants. The Crassulaceae is a medium-sized family

The Verbenaceae ( VUR-bə-NAY-see-ee), the verbena family or vervain family, is a family of mainly tropical flowering plants. It contains trees, shrubs, and herbs notable for heads, spikes, or clusters of small flowers, many of which have an aromatic smell. The family Verbenaceae includes 32 genera and 800 species. Phylogenetic studies have shown that numerous genera traditionally classified in Verbenaceae belong instead in Lamiaceae. The mangrove genus Avicennia, sometimes placed in the Verbenaceae or in its own family, Avicenniaceae, has been placed in the Acanthaceae. Economically important

Lythraceae is a family of flowering plants that includes 28 genera and about 620 species of herbs, shrubs, and trees. The larger genera include Cuphea (275 spp.), Lagerstroemia (56), Nesaea (50), Rotala (45), and Lythrum (35). It also includes the members of the former families of the pomegranate (Punica granatum, formerly in Punicaceae) and of the water caltrop (Trapa natans, formerly in Trapaceae). Lythraceae has a worldwide distribution, with most species in the tropics, but ranging into temperate climate regions as well. The family is named after the type genus, Lythrum, the loosestrifes

Gelsemium sempervirens is a twining vine in the family Gelsemiaceae, native to subtropical and tropical America: Honduras, Guatemala, Belize, Mexico (Chiapas, Oaxaca, Veracruz, Puebla, Hidalgo), and southeastern and south-central United States (from Texas to Virginia). It has a number of common names including yellow jessamine or confederate jessamine or jasmine, Carolina jasmine or jessamine, evening trumpetflower, gelsemium and woodbine. Yellow jessamine is the state flower of South Carolina. Despite its common name, the species is not a "true jasmine" and not of the genus Jasminum.

Pleurolobus is a genus of flowering plants in the pea family (Fabaceae). It includes six species, which range across sub-Saharan Africa, Yemen, the Indian Subcontinent, Southeast Asia, New Guinea, Micronesia, and Australia.

Malesherbia tubulosa is subshrub native to central Peru. It is colloquially called Mullaca and Verónica. M. tubulosa can reach heights of 2 meters and has actinomorphic orange flowers. Compared to other species of Malesherbia, M. tubulosa has relatively high genetic diversity. It is a host for immature Dione (Agraulis) dodona. M. tubulosa is currently classified as endangered due to degradation of natural habitat due to urban expansion.
