List of Genera in Olacaceae


Molecular phylogenetic work (Malecot & Nickrent 2008) has documented that Olacaceae in the traditional sense is polyphyletic. The following classification gives the composition of early diverging Santalales families that we now recognize.  All cases of documented nonparasitism are present in Erythropalaceae whereas all documented parasites are in the remaining families.  

Dulacia (genus should be included in Olax)

  1. Dulacia candida
  2. Dulacia macrophylla


  1. Olax antsiranensis
  2. Olax austrosinensis
  3. Olax aphylla
  4. Olax capuronii
  5. Olax dissitiflora
  6. Olax emirnensis
  7. Olax hypoleuca
  8. Olax imbricata
  9. Olax madagascariensis
  10. Olax pendula
  11. Olax phyllanthi
  12. Olax scandens
  13. Olax stricta
  14. Olax sp.
  15. Olax sp.
  16.  Olax sp.


  1. Ptychopetalum olacoides (or P. uncinatum)
  2. Ptychopetalum petiolatum


The most recent molecular phylogeny of "Olacaceae" is by Malécot and Nickrent (2008).  A pdf file for that paper can be seen by clicking HERE.
