Morphology of Inflorescences in Verbenaceae-Verbenoideae. This paper deals with the interpretation, description and typological characterization of the inflorescences of the genera belonging to the tribe Verbeneae . All the cases belong to the polytelic type of synflorescences. Florescences of almost all genera are dense spikes with decussate bracts. Only Tamonea has loose, spiciform racemes with disperse bracts.
Floral prophylls are always absent.
The heterothetic pleiobotryum is the most frequent branching form, present in Verbena , Glandularia and Hierobotana . Urbania and Junellia have monobotrya. Homothetic pleiobotrya characterize all species of Tamonea . Heteroblastic development of the branches can be observed in several species of Junellia . The heterothetic paniculiform pleiobotryum has been mentioned for several families of the Angiospermae as a primitive or central form, from which other forms derived through processes such as condensation, reduction and truncation.
