  Crypteroniaceae - Encyclopedia, History, Geography and Biography
The Crypteroniaceae are native to tropical lowland and submontane rain forests.
Morphological analyses, supported by recent Chlorplast DNA analysis, indicates that the Crypteroniaceae are most closely related to four small Myrtales families: Penaeaceae, Oliniaceae, and Rhynchocalycaceae of southern Africa, and Alzateaceae of Central and South America.
The genera subsequently spread from India to the moist tropical forests of Southeast Asia.

Maximum parsimony and likelihood analyses of rbcL sequences suggested that Crypteroniaceae should be restricted to Crypteronia, Axinandra, and Dactylocladus and that Crypteroniaceae, so defined, are sister to a clade formed by three small S African taxa (Oliniaceae, Penaeaceae, and Rhynchocalycaeae) and the monotypic S American Alzateaceae.
Three molecular dating approaches (maximum likelihood under a molecular clock, Langley-Fitch, and penalized likelihood) were used to infer the age of Crypteroniaceae using both paleobotanical and geologic calibrations.
Our results argue for an ancient Gondwanan origin of Crypteroniaceae in the Early to Middle Cretaceous, followed by diversification on the rafting Indian plate in the Early Tertiary and subsequent dispersal to SE Asia.

The main goals of this study were to elucidate the circumscription and detailed phylogenetic relationships of Crypteroniaceae by using evidence from DNA sequences of the chloroplast gene rbcL.
The tree obtained from parsimony analyses of rbcL sequences strongly supported the sister relationship between Crypteroniaceae and a clade comprising the monotypic south American family Alzateaceae and three small families endemic to southern Africa.
The resulting phylogeny will be used as a framework for re-evaluating the evolution of morphological characters and biogeographical history of this clade.

With my Ph.D. student, Frank Rutschmann, we are now examining patterns of diversification in the crown group of Crypteroniaceae in SE Asia and the characteristics of speciation in the sister clade of Crypteroniaceae, which includes the S African Penaeaceae (about 27 species in 7 genera).
By dating the origin of the Penaeaceae crown group, we will try to establish whether the rapid diversification of Penaeceae can be linked to specific events of climatic change during the Neogene in S Africa.
In the course of this research on Crypteroniaceae and Penaeceae (Myrtales) we are comparing the influence of using different dating outgroups, calibration points, genetic partitions, and molecular dating methods on nodal age estimation.

A molecular phylogenetic analysis (rbcL, ndhF, matK) of the order Myrtales and with emphasis on this Myrtaceae clade and its sister group (Melastomataceae, Memecylaceae, Penaeaceae, Rhynchocalycaceae, Oliniaceae, Alzateaceae, Crypteroniaceae) was conducted under maximum parsimony and maximum likelihood.
Sequence evolution in the Myrtaceae clade is significantly slower than in Melastomataceae and somewhat slower than in the Crypteroniaceae clade — illustrating generation time effects.
Various molecular dating approaches were used to infer ages of specific nodes within the Myrtaceae clade of four families using calibrated fossil dates from Myrtaceae, Melastomataceae, Onagraceae, and Combretaceae.
