Sphenostemonaceae
''Sphenostemon'' is the genus of small evergreen trees or shrubs native to New Guinea, Queensland (Australia) and New Caledonia. They have opposite or spiral leaves, and at most small stipules. The small flowers, borne in terminal inflorescences, have free (i.e. unjoined) sepals and petals. The anthers have thick filaments. The fruit, a berry, is fleshy and contains two seeds. The genus is described as "particularly poorly known". Taxonomy In the 2009 APG III system, the genus is placed in the family Paracryphiaceae, along with '' Paracryphia'' and ''Quintinia''.

APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families followi ...

Paracryphiaceae
The Paracryphiaceae are a family of woody shrubs and trees native to Australia, southeast Asia, and New Caledonia. In the APG III system of 2009, the family is placed in its own order, Paracryphiales, in the campanulid clade of the asterids. In the earlier APG II system, the family was unplaced as to order and included only ''Paracryphia''. As presently circumscribed, the family includes three genera: * ''Paracryphia'' Baker f. – 1 species, endemic to New Caledonia * ''Quintinia'' A.DC – 25 species in the Philippines, New Guinea, the east coast of Australia, New Zealand and New Caledonia; formerly placed in the Quintiniaceae * ''Sphenostemon'' Baill. – 10 species in New Guinea, Australia (Queensland) and New Caledonia; formerly placed in the Sphenostemonaceae The evolutionary (phylogenetic In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of th ...
