Eighty‐four pollen samples were obtained for 80 taxa, of which, 13 species and one variety are from sect. Brachycalyx Sweet, 58 species and two varieties from sect. Tsutsusi Sweet, and six species from subgen. Pentanthera (G. Don) Pojarkova, respectively. Pollen morphology of all samples was observed using LM and SEM. Pollen grains are revealed to be spheroidal and tetrahedral with tricolporate apertures. Pollen sizes of subgen. Tsutsusi (Sweet) Pojarkova range from 37.67 μm to 61.06 μm, and… Expand
Pollen morphology of Rhododendron L. and related genera and its taxonomic significance
TLDR
Palynological features showed little usefulness in the infrageneric classification of Rhododendron, however, they gave additional support to the individualgeneric status of Menziesia and Tsusiophyllum , and the sister relationship between Rhododendedron and Therorhodion. Expand
Can pollen sculpture in Rhododendron subsec. Rhodorastra differentiate species?
TLDR
The pollen of Rhododendron ledebourii from various populations in Altai revealed sculpture elements characteristic of R. dauricum, R. mucronulatum, and R. sichotense, questioning the taxonomic position of the former species. Expand
Evolution of Angiosperm Pollen: 8. Lamiids1
TLDR
The evolutionary patterns of pollen morphology found in this study reconfirm several previously postulated evolutionary trends, which include a increase in aperture number, a transition from equatorially arranged apertures to globally distributed ones, and an increase in exine ornamentation complexity.

TLDR
Pollen grains of 20 species of 5 subgenera in the genus Rhododendron L. were observed by scanning electron microscope(SEM) and the difference of pollen exine sculpture between sections inThe genus can provide palynology proof for further taxonomy, however, the identification of some certain species in Rhododendedron by morphological data of pollen should be analyzed carefully.

Pollen morphology of the Rhodoreae (Ericaceae) and its systematic implication
TLDR
The morphology of pollen did not fit for identify the subgenera as prmary character, and which can use for identification of some species in Rhododendron, but the difference of pollen exine sculpture between sections or subsections in subGenera can provide palynology proof and showed the important taxonomic significance.

[Study on morphological characteristics of pollen grains of Pinellia ternata in different populations].
