Abstract Section Brachycalyx Sweet comprises nearly 30 species in Rhododendron L. subg. Tsutsusi (Sweet) Pojark. (Ericaceae) and is mainly distributed from China to Japan as well as eastern Asia. A taxonomic revision of section Brachycalyx is proposed and eight species with one subspecies are recognized. Rhododendron dilatatum Miq. var. decandrum Makino is newly recognized at the new rank of subspecies as R. dilatatum subsp. decandrum (Makino) X. F. Jin & B. Y. Ding. Lectotypes are designated… 
Contrasting diversification history between insular and continental species of three‐leaved azaleas (Rhododendron sect. Brachycalyx) in East Asia
The rapid diversification in the insular species during the Quaternary may be a result of genetic drift due to population isolation and population decline on the islands, and widespread migration or colonization may have prevented allopatric speciation in the continental species.


Sectional relationships in the genus Rhododendron (Ericaceae): evidence from matK and trnK intron sequences
Phylogenetic relationships among all eight subgenera and 12 sections in Rhododendron as well as its related genera were inferred from matK and trnK intron sequences to provide insights into paraphyletic and monophyletic relationships.
A new infrageneric classification and phylogenetic trends in the genusRhododendron (Ericaceae)
From a synoptical comparison of morphological, anatomical and phytochemical characters a new system for the genus Rhododendron is proposed, and phylogenetic character progressions and relationships among subgenera, sections and subsections are discussed and illustrated.
Validation of Rhododendron huadingense (Ericaceae), the name of a species endemic to China
The name of Rhododendron huadingense B. Fang, described from Zhejiang Province in 1990, was not a validly published name because two collections were designated as the type, but the name is validated here, with the flowering specimen designate as the holotype.
A revision of Rhododendron VI. Subgenus Pentanthera (Sections Sciadorhodion, Rhodora and Viscidula )
A revision of the seven species of Rhododendron sections Sciadorhodion, Viscidula and Rhodora (of subgenus Pentanthera ; Ericaceae) is presented, and a cladistic analysis results in the recognition of four sections.
Rhododendron chilanshanense (Ericaceae) , a new species from Taiwan
Rhododendron chilanshanense , a new species of Rhododendron subgenus Tsutsusi sect. Brachycalyx , is described from Taiwan. It is distinguished from closely related species by its leaves scattered
A revision of Rhododendron . IV Subgenus Tsutsusi
A revision of Rhododendron subgenus Tsutsusi is presented: section Tsutsusi with 66 species is equivalent to series Azalea subser. Obtusum ; and section Brachycalyx with 15 species includes some
Pollen morphology of Rhododendron subgen. Tsutsusi and its systematic implications
Pollen grains are revealed to be spheroidal and tetrahedral with tricolporate apertures, and the exine sculptures are more or less compactly granulated.

Phylogenetic Relationship of Subgenus Tsutsusi (Rhododendron) Based on ITS Sequences
The sequences of nrDNA internal transcribed spacers, including 5 8S rDNA, were analyzed to reconstruct the phylogeny of Subg Tsutsusi and Subg Pentanthera using parasimony methods and R redowskianum Maxim of subg Therorhodion as outgroup.
