Zenia is a genus of plants in the family Fabaceae. It belongs to the subfamily Dialioideae. It contains a single species, Zenia insignis. The Fabaceae family is known for their extraordinary ability to be efficient in symbiotic nitrogen-fixation. The Papilionoidea and Caesalpinioideae subfamilies have been found to be the two sister families that the Z. insignis seemed to diverge from, through the evidence of fossil calibration points. Based on genetic research, the Z. insignis appears to have lost the genes relating to key-nodulation during its evolution. This results in the tree's inability

It is known from about ten occurrences in central San Diego County, California, and fewer than 100 individual plants on land across the border in Baja California. The plant was first described in 1946 when found at the type locality near El Cajon, California, and all the individuals known in California are located within a six-square-mile area there. Although rare, numbering about 9,000 plants total in existence, the species is relatively well protected in its habitat and a

Microberlinia brazzavillensis is a tree in the family Leguminosae, found in West Africa. It is also called zebrano, zingana, and allen ele, and is commonly sold in the US as zebrawood. The tree is tall and straight, growing up to 40 m in height with a diameter of up to 1 m. The flower has white petals and, as other legumes do, the tree produces pods. Concern is expressed due to the tree's rarity in some areas of its native tropical habitat in Gabon and Cameroon, typically less than one tree per square kilometre. It is listed on The IUCN Red List of Threatened Species as vulnerable The wood is
