Neltuma pallida (formerly Prosopis pallida) is a species of mesquite tree. [1] It has the common names kiawe (/ k iː ˈ ɑː v eɪ /) [2] (in Hawaii), huarango (in its native South America) and American carob, as well as "bayahonda" (a generic term for Prosopis), "algarrobo pálido" (in some parts of Ecuador and Peru), and "algarrobo blanco" (usually used for Prosopis alba).
Which Southern California native plants survived climate change and mass extinctions 13,000 years ago and still live today? La Brea Tar Pits researchers compiled a list.
Killylea (/ k ɪ l iː ˈ l eɪ /; from Irish Coillidh Léith 'grey forest') is a small village and townland in Northern Ireland. It is within the Armagh City and District Council area. The village is set on a hill, with St Mark's Church of Ireland , built in 1832, at its summit.
A sundew with a leaf bent around a fly trapped by mucilage. Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms.These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage.

Most of these plants have true roots and leaves, and many were quite tall. The tree-like Archaeopteris, ancestral to the gymnosperms, and the giant cladoxylopsid trees had true wood. These are the oldest known trees of the world's first forests. Prototaxites was the fruiting body of an enormous fungus that stood more than 8 meters tall. By the ...
It is a medium-sized evergreen tree growing to 20 m tall. The leaves are palmately compound, with 9–11 leaflets 10–20 cm long and 2.5–4 cm broad, on a 20 cm petiole. The flowers are white, produced 20 or more together in a 10 cm long inflorescence ; it is dioecious , with male and female flowers on separate trees.
Archaeopteris is a member of a group of free-sporing woody plants called the progymnosperms that are interpreted as distant ancestors of the gymnosperms. Archaeopteris reproduced by releasing spores rather than by producing seeds, but some of the species, such as Archaeopteris halliana were heterosporous, producing two types of spores.
The morphology of Araliaceae varies widely. Many studies have found that there is no unifying characteristic capable of classifying the family. [6] In general, Araliaceae species have large, usually alternate leaves, often with aromatic ethereal oils, five-petaled flowers, two to five carpels, simple umbels, and berries without carpophores or oil cavities.
