Erythrina alkaloids, generally containing benzyl-tetrahydroisoquinoline structure, are widely distributed in Erythrina species, a genus of plants which belong to the Fabaceae family in tropical and subtropical regions. The Erythrina alkaloids can be found in several organs of Erythrina trees but are primarily found in their seeds. They display ...
Erythrina / ˌ ɛr ɪ ˈ θ r aɪ n ə / [4] is a genus of plants in the pea family, Fabaceae. It contains about 130 species , which are distributed in tropical and subtropical regions worldwide. They are trees , with the larger species growing up to 30 m (98 ft) in height.
Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.
Erythrina fusca is a species of flowering tree in the legume family, Fabaceae. It is known by many common names, including purple coraltree, gallito, bois immortelle, bucayo, and the more ambiguous "bucare" and "coral bean". E. fusca has the widest distribution of any Erythrina species; it is the only one found in both the New and Old World.
Note 1: Modification of definition in ref. [2] A dispersion is a system in which distributed particles of one material are dispersed in a continuous phase of another material. The two phases may be in the same or different states of matter .
Seeds are visible, but restrained by the cup-like ring created by the encircling keels. The final requirement for dispersal is rainfall, or sufficient moisture, to flush seed from this barrier, colloquially termed the splash cup. [27] Seed that overflows or splashes from the cup is dispersed to the nearby ground.
Epilobium hirsutum — Seed head. In the broadest sense, dispersal occurs when the fitness benefits of moving outweigh the costs. There are a number of benefits to dispersal such as locating new resources, escaping unfavorable conditions, avoiding competing with siblings, and avoiding breeding with closely related individuals which could lead to inbreeding depression.
No non-native species of Erythrina is known to be naturalized in Hawaiʻi. [4] The wiliwili is distinguished from the other seven cultivated species by a pod with only one to three red or yellow-orange seeds, which sink in water; [10] non-native Erythrina have pods with larger numbers of brown seeds, which float in water.
