Kelps are large brown algae seaweeds that make up the order Laminariales. There are about 30 different genera.
Plum
Plum has many species, and taxonomists differ on the count. Depending on the taxonomist, between 19 and 40 species of plum exist. From this diversity only two species, the hexaploid European plum ("Prunus domestica") and the diploid Japanese plum ("Prunus salicina" and hybrids), are of worldwide commercial significance. The origin of these commercially important species is uncertain but may have involved P. cerasifera and possibly P. spinosa as ancestors. Other species of plum variously originated in Europe, Asia and America.
