Input: Question: Which mountains the Dyke climbed were the highest? Passage:In his spare time during his working life, he climbed the Cape Peninsula mountains, the Hottentots-Holland mountains, and nearby ranges, all of which are spectacular examples of Fynbos, including Peninsula Granite Fynbos, Peninsula Sandstone Fynbos and a number of related biomes. Later, when the railway administration moved to Johannesburg, he continued his explorations in various parts of the Drakensberg mountains, as well as on visits to Lesotho. On such excursions he collected avidly and sent specimens to Dr Rudolf Marloth. He extended his explorations to other regions as well; for example, while climbing the Cockscomb Mountains in the Winterberg range near Uitenhage he discovered a hitherto unrecognised species of Protea, later named Protea dykei Phill (now seen as a synonym of Protea rupicola). On Matroosberg in the Hex River Mountains, he discovered a new species of "everlasting", flowers that in those days were generally included in the genus Helichrysum. That species was described by Harry Bolus under the name Helichrysum dykei Bolus. The genus has since been split however, and the species has been assigned to another genus, as Syncarpha dykei (Bolus) B. Nord. Dyke's name also appears in the names of Erica dykei L. Bolus (= Erica thodei Gilg) and Lessertia dykei L. Bolus.
