Morphology of inflorescences in Lippia (Verbenaceae)

This paper deals with the interpretation, description and typological characterization of inflorescences in the genus Lippia L. This genus comprises 160 species, mainly distributed in tropical and temperate America, with only a few species growing in the Old World, of which 60 have been studied. The...

This genus comprises 160 species, mainly distributed in tropical and temperate America, with only a few species growing in the Old World, of which 60 have been studied. The inflorescences are of compound polytelic type, with bracteate capituliform spikes as florescences. The phyllotaxis, form, size and colour of the bracts have taxonomic value, these characters correspond with the sections of the genus. In section Dipterocalyx, the inflorescences are bracteate or frondose-bracteate heterothetic pleiobotrya; in the remaining sections the inflorescences are homothetic pleiobotrya. Series Corymbosae and Paniculatae, and some species of section Dioicolippia, have bracteate or frondose-bracteate inflorescences, while the remaining sections have frondose ones. Section Goniostachyum and subsection Mexicanae have numerous paraclades per axile, while the other sections have 1-2 paraclades per axile. Section Pseudoaloysia (Lippia lasiocalycina Cham.) is characterized by the production of flowers in two stages: first, on bracteate brachyblasts with proliferation and the second on frondose macroblasts, which are originated by the first brachyblasts. The heterothetic pleiobotra have been mentioned as the primitive form from which other inflorescences were derived. If this hypothesis is correct, the species of section Dipterocalyx may possibly be the ancestral group, from which the homothetic pleiobotrya of other sections derived. 1998 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_00116793_v36_n_p1_MulguraDeRomero http://hdl.handle.net/20.500.12110/paper_00116793_v36_n_p1_MulguraDeRomero
