Hakea drupacea?
The
scientific names for aliens proteas used in SASOL Proteas were those named in Wrigley
& Fagg "Banksias, Waratahs & Grevilleas and all other plants in the
Australian Proteaceae Family" published in 1989 by Collins, and the list of
Arnold and De Wet (1993) which lists all the scientific synonyms. However, in 1990, R.M.
Barker of the Adelaide Botanic Gardens State Herbarium, reviewed the names of some of the Hakea
species.
Ha suaveolens has a single synonym listed in Wrigley and Fagg: Ha pectinata. Ha suaveolens was coined by Robert Brown in 1810. Brown was obviously unaware that C.F. Gaertner had published the same species as Conchium drupaceum in 1807. In 1818 Roemer and Schultes (1818) transferred the species to the genus Hakea. However, their listing was "mechanical" - they merely transferred all the species in Conchium to Hakea. It seems that they did not see a specimen as they noted the entry as "?Hakea drupacea". Bentham was the first to suggest that Ha drupacea was the same as Ha suaveolens. So why was the name not adopted?
The problem appears to be that the collector of the specimen, Labillardiere, in 1804 misidentified Conchium drupaceum as Ha gibbosa. He did however, describe other species of Hakea, some of which he compared to "Ha gibbosa". Presumably his comparisons are thus with Ha suaveolens.
What is today Hakea gibbosa was described in 1798 when Sir James Edward Smith described the genus Conchium, apparently unaware that Heinrich Adolph Schrader had described the genus Hakea in 1797 based on the species H. glabra. However, Richard Salisbury had described the same species as Banksia teretifolia in 1796, so that while we use Schrader's generic name, for the Dagger Hakea we use Salisbury's species name. With a name like Dagger Hakea we can count ourselves fortunate that Ha teretifolia was not established in South Africa - it is one of the hardiest Hakeas, accepting poor drainage and forming "good prickly screens" and can also be seen growing on coastal cliffs south of Newcastle.
Atlassers may atlas this species as either Ha suav or as Ha drup. An automatic update will be made by blikbrein on receipt of your data.
