his new genus Leucadendrum, with newcomers Leucadendrum cordifolium, Leucadendrum gracile, Leucadendrum parile, Leucadendrum royenaefolium, Leucadendrum saxatile and Leucadendrum truncatulum, all of which are now included in Leucospermum with the identical species name. It is assumed that Salisbury had based his review on a draft he had been studying of a paper called On the natural order of plants called Proteaceae that Robert Brown was to publish in 1810. Brown however, called the genus Leucospermum, distinguished eighteen species and made the new combinations Leucospermum lineare and L. spathulatum. Salisbury's names were ignored by botanists in favour of those that Brown had created, and this was formalised in 1900 when Leucospermum was given priority over Leucadendrum. Johann Friedrich Klotzsch described L. pedunculatum in 1845. Carl Meissner, who contributed a section on the Proteaceae in 1856 to the series Prodromus Systematis Naturalis Regni Vegetabilis by Alphonse Pyramus de Candolle, recognised twenty-three species, including seven new ones: L. gueinzii, L. mundii, L. reflexum, L. oleaefolium var. brownii (now L. bolusii), L. zeyheri var. truncatum (now L. truncatum), L. attenuatum var. praemorsum and var. ambiguum (now L. praemorsum and L. erubescens). Otto Kuntze revised the genus in 1891 and called it Leucadendron, a homonym of a name that had already been used by Linnaeus in 1753 for another group of Proteaceae, which have separate sexes and very large bracts. Edwin Percy Phillips newly described L. glabrum and L. muirii in 1910, Spencer Le Marchant Moore portrayed L. saxosum in 1911, while Otto Stapf added L. gerrardii in 1912. In 1912, Phillips and Otto Stapf revised Leucospermum and recognised thirty-one species. Afterwards, Phillips described L. cordatum (1923) and L. patersonii (1928). Robert Harold Compton added L. wittebergense in 1931 and L. catherinae in 1933. This was followed by L. arenarium by Hedley Brian Rycroft in 1959. John Patrick Rourke in 1970 distinguished forty-seven species, eight of which new to science: L. erubescens, L. fulgens, L. innovans, L. pluridens, L. praecox, L. profugum, L. secundifolium and L. utriculosum. He later added the newly discovered L. winteri in 1978, L. hamatum in 1983, and L. harpagonatum in 1994. Rourke erected several sections in 1970, among which Xericola, to which he assigned L. alpinum including a subspecies amoenum, L. obtusum including a subspecies albomontanum, as well as L. secundiflorum. In 1984, he erected a new genus Vexatorella to which he moved these taxa, with the exception of L. secundiflorum,
