'''''Lasjia''''' is a genus of six species of trees of the family Proteaceae.<ref name=Mast-etal-2008/><ref name=APNI/><ref name="RFK8-Proteaceae"/> Three species grow naturally in northeastern Queensland, Australia, and three species in Sulawesi, Indonesia.<ref name=Mast-etal-2008/><ref name=McDonald-Ismail-1995-M.-erecta/><ref name=Gross-Hyland-1993-M.-claudiensis-grandis/><ref name=Fl-Malesiana-1955-M.-hildebrandii/> Descriptively they are the tropical or northern macadamia trees group.<ref name=Gross-Hyland-1993-M.-claudiensis-grandis/> ''Lasjia'' species characteristically branched compound inflorescences differentiate them from the ''Macadamia'' species, of Australia, which have characteristically unbranched compound inflorescences and only grow naturally about {{Convert|1000|km|abbr=on}} further to the south, in southern and central eastern Queensland and in northeastern New South Wales.<ref name=Gross-Hyland-1993-M.-claudiensis-grandis/>

The Bama aboriginal Australian peoples in the late 1800s Bellenden Ker Range rainforests (north east Queensland) taught European–Australian scientists of ''L. whelanii'' trees bearing the large seeds "extensively used for food".<ref name=Bailey-1889-Bellenden-Report-Ag-Dept/><ref name=Horsfall-Hall-1990/> One of those scientists, colonial botanist Frederick M. Bailey, collected and in 1889 formally published a scientific description of specimens of them under the name ''Helicia whelanii'' and later again in 1901 as a species of ''Macadamia''. Of these five ''Lasjia'' species, it was the first to receive a European–Australian scientific name.<ref name=APNI/><ref name=Bailey-1889-Bellenden-Report-Ag-Dept/><ref name=Dowe-Broughton-2007/>

==Names and classification==

Genetics studies published in 2008 by Austin Mast and colleagues show they have separated from the genus ''Macadamia'', correlating less closely than previously thought from morphological studies. The ancestors of ''Lasjia'' appear to have diverged just under 30 million years ago in the Oligocene epoch from a lineage which has given rise to the Australian genus ''Macadamia'', the South African species ''Brabejum stellatifolium'', Australian rainforest species ''Nothorites megacarpus'', and South American genus ''Panopsis''.<ref name=Mast-etal-2008/>

The genus name was coined from the initials of Lawrence Alexander Sidney Johnson (LASJ), who had done much pioneering work on the Proteaceae. The type species is ''Lasjia claudiensis''.<ref name=Mast-etal-2008/><ref name=Gross-Hyland-1993-M.-claudiensis-grandis/> ''L. claudiensis'' and ''L. grandis'' were only formally scientifically described as recently as 1993 under the genus ''Macadamia'', with botanists making field collections of scientific specimens only since about 1948.<ref name=Gross-Hyland-1993-M.-claudiensis-grandis/><ref name=Flora-Australia/> Genetics studies published in 2008 reported ''L. whelanii'' as the earliest offshoot within the genus.<ref name=Mast-etal-2008/>

==Descriptions and natural distributions==

All species grow naturally into trees, with whorled, simple adult leaves with smooth margins (unserrated, spineless) and bearing their flowers in branched compound inflorescences generally at the ends of the foliage or sometimes from older branches under the foliage.<ref name=Mast-etal-2008/><ref name=Coopers-2004/> The fruits of ''L. claudiensis'', ''L. grandis'', ''L. hildebrandii'', and ''L. whelanii'' have thin inner shells (testae) of about {{Convert|1|-|2|mm|2|abbr=on}} unlike the well-known macadamia nuts' thicker woody inner shells.<ref name=Gross-Hyland-1993-M.-claudiensis-grandis/><ref name=Fl-Malesiana-1955-M.-hildebrandii/><ref name=Wrigley-1991/>

''Lasjia claudiensis'' and ''L. grandis'' have significantly larger fruits and seeds; they have fruit diameters of {{Convert|6.5|±|1.5|cm|in|1|abbr=on}} and {{Convert|5|-|7|cm|in|1|abbr=on}}, respectively, and seeds diameters of {{Convert|5.5|-|6.5|*|5|cm|in|adj=mid|long|1|abbr=on}} and {{Convert|3|-|4|cm|in|1|abbr=on}}, respectively.<ref name=Gross-Hyland-1993-M.-claudiensis-grandis/><ref name="RFK8-L.claudiensis"/><ref name="RFK8-L.grandis"/>

''Lasjia claudiensis'' is endemic to the Iron Range region of Cape York Peninsula, far north Queensland, in more seasonally dry rainforests and gallery forests, from about {{Convert|0|to|600|m|ft|abbr=on}} altitude.<ref name=Gross-Hyland-1993-M.-claudiensis-grandis/><ref name=Flora-Australia/><ref name="RFK8-L.claudiensis"/><ref name=Coopers-2004/> ''L. claudiensis'' has the Australian national conservation status listing of "vulnerable" in the Australian government Environment Protection and Biodiversity Conservation Act 1999 (EPBC),<ref name=Aust-Vulnerable-Sp/> and the Queensland official state conservation status of "vulnerable" species in the Queensland government Nature Conservation Act 1992.<ref name=QLD-NatureConWiR06/>

''Lasjia grandis'' grows naturally only in the rainforests of the Wet Tropics region of northeastern Queensland, from about {{Convert|0|to|460|m|ft|abbr=on}} altitude.<ref name=Gross-Hyland-1993-M.-claudiensis-grandis/><ref name=Flora-Australia/><ref name="RFK8-L.grandis"/><ref name=Coopers-2004/> ''L. grandis'' trees received their name for growing to the largest size of the macadamia group,<ref name=Gross-Hyland-1993-M.-claudiensis-grandis/> of up to about {{Convert|40|m|ft|-1|abbr=on}}, with trunks up to {{Convert|120|cm|in|0|abbr=on}} diameter, with some having buttresses. ''L. grandis'' has an official Queensland state conservation status of "vulnerable" species in the Queensland government Nature Conservation Act 1992.<ref name=QLD-NatureConWiR06/>

''Lasjia whelanii'' grows naturally only in the rainforests of the Wet Tropics region of northeastern Queensland, from about {{Convert|0|to|700|m|ft|abbr=on}} altitude.<ref name=Flora-Australia/><ref name="RFK8-L.whelanii"/><ref name=Coopers-2004/>

''Lasjia hilderbrandii'' and ''L. erecta'' are endemic to Sulawesi (Indonesia) and its smaller adjacent islands, and there's even less published knowledge of them.<ref name=McDonald-Ismail-1995-M.-erecta/><ref name=Fl-Malesiana-1955-M.-hildebrandii/> Up to the date of 1995, all populations of ''L. hilderbrandii'' were found below {{Convert|450|m|ft|abbr=on}} altitude, except one specimen collection. A collection beyond Sulawesi was made in west Sumatra, although whether its origin was natural and a significant extension of range or a recently introduced plant, was unconfirmed in 1995.<ref name=McDonald-Ismail-1995-M.-erecta/> Up to 1995, all populations found of ''L. erecta'' were between {{Convert|900|and|1700|m|ft|abbr=on}} altitude.<ref name=McDonald-Ismail-1995-M.-erecta/> Therefore, as far as was known in 1995, the two species have separate habitats and geographic distributions (allopatric).<ref name=McDonald-Ismail-1995-M.-erecta/> The two species clearly have a close evolutionary relationship with many characteristics in common, endemic to the Sulawesi region, the flower structures in whorls of racemes at the ends of uppermost branches and the whorled leaves with smooth margins.<ref name=McDonald-Ismail-1995-M.-erecta/> The distinctive characteristics of ''L. erecta'' of short and erect flower structures and of smaller leaves in whorls of four compare to the characteristics of ''L. hildebrandii'' of flower structures longer and arching or pendulous and of larger leaves in whorls of five to seven.<ref name=McDonald-Ismail-1995-M.-erecta/>

==Uses for foods==

Peoples of Sulawesi (Indonesia) make foods from the uncertain and inconclusively toxic or nontoxic seeds of ''L. hildebrandii'', according to incomplete English language documentation.<ref name=McDonald-Ismail-1995-M.-erecta/><ref name=Gross-Hyland-1993-M.-claudiensis-grandis/><ref name=Fl-Malesiana-1955-M.-hildebrandii/><ref name=Hardner-etal-2009-Genetic-Res/>

Umpila and related peoples in the Iron Range region make use of ''L. claudiensis'' and Bama peoples of the Wet Tropics region also make use of ''L. grandis'', apparently knowing them well for their uses and regarding their distributions, respectively.<ref name=Horsfall-Hall-1990/> Only in recent decades has English-language botanical science recognised, described, and published brief documentation about these two species, with more learning or field work required to record their full distributions and uses.<ref name=Gross-Hyland-1993-M.-claudiensis-grandis/><ref name="RFK8-L.claudiensis"/><ref name="RFK8-L.grandis"/><ref name=Aust-Vulnerable-Sp/> The few documents available are the brief journal paper formally scientifically describing these two species,<ref name=Gross-Hyland-1993-M.-claudiensis-grandis/> the published archaeological work of Nicky Horsfall's journal papers and PhD and the reports of the 1889 Archibald Meston expedition; the latter two bodies of work were undertaken in the Bellenden Ker Range region.<ref name=Horsfall-Hall-1990/><ref name=Hill-Baird-2003/>
