DescriptionLyallia kerguelensis is a plant known from Kerguelen Island in the south Indian Ocean and from New Zealand. It is a low-lying, cushion-forming plant that grows in rocky habitats. This particular specimen was collected by the famous nineteenth century botanist Joseph D. Hooker, assistant surgeon (and expedition botanist) on the H.M.S. Erebus during its circumnavigation of Antarctica together with its sister ship, the H.M.S. Terror, from 1839 to 1843. This specimen is of particular interest to botanists, because it is believed to be type material, that is, a portion of the plant material from which Hooker originally described and named the plant. He named it Lyallia after David Lyall, who was the assistant surgeon on the Terror, and a keen botanist as well, and kerguelenensis after the islands on which it was collected. This specimen of Lyallia kerguelensis is contained in a scrapbook that was compiled by Mr. Adam White who was employed in the Department of Zoology in the British Museum, from 1835 to 1863. Though he worked primarily as an entomologist, Adam White evidently was a lover of plants and so compiled scrapbooks of plant specimens that were given to him by botanical explorers from different lands. Each specimen is accompanied by a handwritten inscription with, at a minimum, the collection date, collector, and collecting locality. Two of Adam White’s scrapbooks were donated to the University of Toronto vascular plant herbarium (known internationally as TRT) and were later transferred with the herbarium to the ROM.
