Phylogenetics of the New World Subtribes of Asclepiadeae (Apocynaceae—Asclepiadoideae): Metastelmatinae, Oxypetalinae, and Gonolobinae
This study provides a framework for future study of the American MOG genera and highlights areas that need further attention and Chromosome numbers indicate a tendency for reduction in several clades.

Asclepiadeae classification: evaluating the phylogenetic relationships of New World Asclepiadoideae (Apocynaceae)
Comparing the taxonomic arrangement of subtribes with a topology obtained through analyses of two plastid DNA regions for 111 species of Asclepiadoideae representing the major lineages of the subfamily shows that without Jobinia, Nephradenia and Barjonia, AsclePIadeae are not monophyletic.
Secamone (Asclepiadaceae subfam. Secamonoideae) in Africa
- D. Goyder
The traditional boundaries of Secamone have been retained for this study pending a revision of the subfamily at generic level and a number of so-called primitive characters with the Periplocoideae and, in many cases, also with Apocynaceae are shared.

Notes on the African Genus Glossostelma (Asclepiadaceae)
- D. Goyder
Corona morphology appears useful for species delimitation, but is sometimes obscured in the past by reliance on few characters which have been given excessive weight in classifications of the group, particularly those concerned with the corona.

The existence of extensive peat deposits in the Cuito river system for the first time is noted and it is suggested that one of Barbosa’s vegetation types in the area needs to be reassessed.

Whether milkweeds have a drier climate niche is tested by comparing milk weeds with plesiomorphic traits (Secamonoideae) and the milkweed sister group in continental Africa, consistent with a shift from rainforests to dry forests in a cooling climate.
