(F. Muell.) A.C.Sm. & Hass
The genus was named after Rev. John Ignatius Bleasdale, (1822- 1884) who
arrived in Victoria, Australia from Britain in 1851. He was a founder member of the Melbourne Microscopical
Society, and fellow of the Geographical and Linnean societies, and an honoray member of the Medical Society of
Victoria. He was also an enthusiastic advocate of the wine industry in Victoria and Frank Potts (1815-1890) named
his Bleasdale Winery, in Langhorne Creek SA, after him.
Ferdinand Mueller was director of the Royal Botanic Gardens Melbourne from
1857 to 1873, at a time in which he was describing plants collected from all over Australia by exploring botanists.
In that context he described and published the new species Grevillea bleasdalei in Fragmenta
Phytographiae Australiae 5(35):90. Type: "in cacumine montis McAllister Australiae tropicae. Dallachy".
Collected by John Dallachy, at the peak of Mt McAllister.
Since 1865 the species has undergone a tortuous history of revision having
been named; Adenostephanus bleasdalei, Keermadecia bleasdlei, Roupala bleasdalei, Euplassa bleasdalei, and
Gevuina bleasdaleia, before being named Bleasdalea bleasdalei by Smith and Hass in 1985.
Even then, Smith and Hass only ten years later renamed it Turrillia
bleasdalei, before it once again reverted to Gevuina bleasdalei. Finally in 2010 it was transferred to
the genus Bleasdalea, which was originally created by Mueller, but because of the rules of naming the
original epithet had to be used, so the Rev John Ignatius Bleasdale became double barrelled!
How long will it last?
