Pelargonium name history

geraniaceae-watercolour-webThe name Pelargonium was originally classified as a Geranium in the early years of discovery but the botanical name was later suggested by Dillenius in his botanical works and illustrations which included 7 species of Geraniums from South Africa and was based on the Greek word pelargo’s because the seed head has the appearance of a storks beak. Johannes burman a Dutch botanist and physician in 1753 mentioned the differences in species and organized them into the same genus Geranium, The name Pelargonium however was not actually established until Charles Louis L’H’eriter de Brutelle a French botanist and magistrate classified the pelargonium by the quantity of stamens in the flower, in which most pelargoniums have seven and divided them into two different genera. De Candolle in 1824 again split the genus into 12 different sections to show the different types of pelargoniums, some having longer petioles, thicker roots or leaf shapes etc, later extended to 16 sections by Knuth 1912.
The sections include Campylia, Chorisma, Cicronium, cortusina,Glaucophyllum,Hoarea,Isopetalum, Jenkinsonia,Ligularia,Myrrhidum,Otidia,Pelargonium,Peristera de Candolle,Polyactium de candolle,Reniforme,Subsucculentia
