Ulva spp. with Ulva fenestrata. A contemporary scan incorporating an illustration by Alexander Postels from Illustrationes algarum (1840). Ulva fenstrata is now Ulva lactuca or sea lettuce. Alexander Postels was a German-born geologist brought on to the Russian exploratory expedition to Alaska in 1829, captained by Frederick Luetke. Postels demonstrated a genius for sketching and an affinity for the enormous and extraordinary seaweeds found along the Alaskan coast. In 1840, in partnership with the botanist Franz Joseph Ruprecht, Postels created one of the most extraordinary folios of marine algae of all time, Illustrationes algarum. Ruprecht’s descriptions are accompanied by Postels’s dynamic, oversized lithographs of each species rendered in full colour.
