==Taxonomy==
As of [APG IV](/source/APG_IV_system), the species has been moved out of the [Dipterocarpaceae](/source/Dipterocarpaceae) (formerly in subfamily Pakaraimoideae) and is now placed within an expanded Cistaceae due to molecular evidence showing that it is sister to the remainder of Cistaceae.<ref>{{Cite journal|last1=Ducousso|first1=M.|last2=Bena|first2=G.|last3=Bourgeois|first3=C.|last4=Buyck|first4=B.|last5=Eyssartier|first5=G.|last6=Vincelette|first6=M.|last7=Rabevohitra|first7=R.|last8=Randrihasipara|first8=L.|last9=Dreyfus|first9=B.|date=2004|title=The last common ancestor of Sarcolaenaceae and Asian dipterocarp trees was ectomycorrhizal before the India-Madagascar separation, about 88 million years ago|journal=Molecular Ecology|volume=13|issue=1|pages=231–236|doi=10.1046/j.1365-294x.2003.02032.x|issn=0962-1083|pmid=14653803|bibcode=2004MolEc..13..231D |s2cid=33171677}}</ref><ref name="apgiv">{{Citation |last=Angiosperm Phylogeny Group |year=2016 |title=An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG IV |journal=Botanical Journal of the Linnean Society |volume=161 |issue=2 |pages=105–20 |doi= 10.1111/boj.12385|doi-access=free }}</ref>
