Three evolutionary lineages of seaweed: The greens, the reds, and the browns. The basic taxonomic grouping of the seaweeds by colour was established by William Henry Harvey and these scans of Ulva (greens), Chondracanthus and Callophyllus (reds) and Macrocystis pyrifera (browns) sit atop the page from Harvey’s Nereis Boreali-Americana (1852) where he describes these groups. “For purposes of classification, the Algae may be conveniently grouped under three principal heads or sub-classes, which are, for the most part, readily distinguishable by the colour of their frond.” His terms were Melanospermeae (the browns), Rhodospermeae (the reds), and Chlorospermeae (the greens). Although the terminology has changed slightly, the same colour groups are used today.
