Discussion
Genera 8, species 20 (1 in the flora).
Cervantesiaceae show a trend from bisexual to fully unisexual flowers, with intermediate stages seen by the presence of staminodes and pistillodes, as well as trioecy in Scleropyrum Arnott. Carpel number in Cervantesiaceae is unclear and the necessary anatomical studies have not been done. The fruits in this family (the largest in Santalales) have a hard or crustaceous mesocarp. Because the mesocarp is hard, not the endocarp, these are considered pseudodrupes, not true drupes. In Jodina Hooker & Arnott ex Meisner, the endocarp is apparently consumed during endosperm development (S. P. Bhatnagar and G. Sabharwal 1969); this interpretation is extended to other members of the family.
The affinity of the eight genera of Cervantesiaceae, first noted by H. U. Stauffer (1957, 1961), was confirmed using molecular phylogenetic methods (J. P. Der and D. L. Nickrent 2008; Z. S. Rogers et al. 2008). The segregation of Cervantesiaceae from Santalaceae in the broad sense follows the classification of Nickrent et al. (2010). Pyrularia is the only genus in the family with species occurring in both the Old and New Worlds.

None.
