BaphieaeThe tribe Baphieae is one of the subdivisions of the plant family Fabaceae. The Baphieae tribe arose 55.3 ± 0.4 million years ago (in the early Eocene). The Baphieae tribe has been circumscribed to include the following genera, which used to be placed in tribes Sophoreae and Swartzieae: Airyantha Brummitt Baphia Afzel. ex Lodd. et al. Baphiastrum Harms Baphiopsis Benth. ex Baker Bowringia Champ. ex Benth. Dalhousiea Wall. ex Benth. Leucomphalos Benth. ex Planch. This clade does not currently have a node-based, phylogenetic definition.
Root noduleRoot nodules are found on the roots of plants, primarily legumes, that form a symbiosis with nitrogen-fixing bacteria. Under nitrogen-limiting conditions, capable plants form a symbiotic relationship with a host-specific strain of bacteria known as rhizobia. This process has evolved multiple times within the legumes, as well as in other species found within the Rosid clade. Legume crops include beans, peas, and soybeans.
DalbergieaeThe tribe Dalbergieae is an early-branching clade within the flowering plant subfamily Faboideae (or Papilionaceae). Within that subfamily, it belongs to an unranked clade called the dalbergioids. It was recently revised to include many genera formerly placed in tribes Adesmieae and Aeschynomeneae and to be included in a monophyletic group informally known as the dalbergioids sensu lato. The members of this tribe have a distinctive root nodule morphology, often referred to as an "aeschynomenoid" or "dalbergioid" nodule.
StyphnolobiumStyphnolobium is a small genus of three or four species of small trees and shrubs in the subfamily Faboideae of the pea family Fabaceae, formerly included within a broader interpretation of the genus Sophora. It was recently assigned to the unranked, monophyletic Cladrastis clade. They differ from the genus Calia (mescalbeans) in having deciduous leaves and flowers in axillary, not terminal, racemes. The leaves are pinnate, with 9–21 leaflets, and the flowers in pendulous racemes similar to those of the black locust.
SophoreaeThe tribe Sophoreae is one of the subdivisions of the plant family Fabaceae. Traditionally this tribe has been used as a wastebasket taxon to accommodate genera of Faboideae which exhibit actinomorphic, rather than zygomorphic floral symmetry and/or incompletely differentiated petals and free stamens. Various morphological and molecular analyses indicated that Sophoreae as traditionally circumscribed was polyphyletic.
AmburaneaeThe tribe Amburaneae is one of the subdivisions of the plant family Fabaceae. It has been circumscribed to include the following genera, which used to be placed in tribes Sophoreae and Swartzieae: Amburana Schwacke & Taub. Cordyla Lour. (including Dupya) Dussia Krug & Urb. ex Taub. Mildbraediodendron Harms Myrocarpus Allemão Myrospermum Jacq. Myroxylon L.f. Petaladenium Ducke This clade does not currently have a node-based, phylogenetic definition.
Cladrastis cladeThe Cladrastis clade is a monophyletic clade of the flowering plant subfamily Faboideae (or Papilionaceae) that is found in eastern Asia and southern North America. It is consistently resolved in molecular phylogenies and is sister to the Meso-Papilionoideae. Evidence for the existence of this clade was first proposed based on morphological (floral), cytological, and biochemical evidence. It is predicted to have diverged from the other legume lineages 47.4±2.6 million years ago (in the Eocene).
