A consensus classification for the order Gentianales with additional details on the suborder Apocynineae [PDF]
The Gentianales as circumscribed by Benson, Cronquist, Dahlgren, Goldberg, Hey wood et al., Melchior, Stebbins, Takhtajan, and Thorne is investigated. From these a consensus classification (not in the cladistic sense) or classificatory model for the order is proposed.

Neotropical Entomology, 2020
Studies in crop plants analyzing floral biology in conjunction with effectiveness and efficiency of pollinators on pollen transfer and fruit formation are not common, although they are essential to provide better management actions. On this base, we selected a farm in Bahia, Brazil, to study pollination on coffee plants (Coffea arabica L ...

Phylogenetic relationships in the Gentianales with focus on Loganiaceae sensu lato are evaluated using parsimony analyses of nucleotide sequence data from the plastid genes rbcL and ndhF. Inter‐ and intrafamilial relationships in the Gentianales, which consist of the families Apocynaceae (including Asclepiadaceae), Gelsemiaceae, Gentianaceae ...

Development of ovules in Apocynaceae and their evolution in Gentianales
Botanical Journal of the Linnean SocietyAbstract The ovule in Apocynaceae (Gentianales) is described as tenuinucellate and unitegmic. Although this type of ovule is characteristic of Asterids, their origin is widely debated due to variations within the clade, as bitegmic, bifid, or unitegmic ovules are also found in several genera.

Anatomical Structures of the VA Mycorrhiza in the Apocynaceae (Gentianales)
Botanica Acta, 1995AbstractRoots of 19 Apocynaceae species were studied anatomically with respect to their symbiosis with VAM‐fungi. In plants collected from the field, VAM‐fungi were established in the root cortex. Also, inoculations with different Glomus species on the cultured plants are very successful in the infection and colonization of the root cortex.After ...
