Giant Groundsel, Kilimanjaro, Africa, 1934 (colour litho)

Dendrosenecio Johnstonii, formerly Senecio Johnstonii, is a giant groundsel found in the middle altitudes of Mount Kilimanjaro in Africa; from the Asteraceae family, the giant groundsels of the genus Dendrosenecio evolved, about a million years ago, from a Senecio that established itself on Mount Kilimanjaro, with those that survived adapting into Dendrosenecio Kilimanjari; as it moved down the mountain, the adaptations necessary for the new environment created the new species, Dendrosenecio Johnstonii; named after Sir Henry Johnston (1858-1927) British explorer, botanist and colonial administrator; illustration from a series of illustrations of 'Bizarre Trees', produced for the market in Europe by Liebig as promotional trade cards; le seneçon de Johnston;
