Alpinia (Zingiberaceae): A Proposed New Infrageneric Classification
K. Schumann's classification of Alpinia (Zingiberaceae), which subdivided the genus into five subgenera and 27 sections, was based, in the main, on the character of the secondary bracts (bracteoles). It is here proposed that the subgenera be reduced to two—Alpinia (7 sections and 10 subsections) and Dieramalpinia (4 sections and 2 subsections), and ...

Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

We determined the trophic associations among fig wasp species associated with Ficus citrifolia by integrating gall morphology, the temporal sequence of wasp colonization, and oviposition behaviour. Dissection of galls produced by four gall‐inducing species at a late developmental phase enabled direct identification of occupants and inference of host ...
