Pollen Morphology in the Order Centrospermae
TLDR
Pollen morphology reinforces the placement of the Cactaceae and Didiereaceae in the order, and would support the inclusion of Dysphania in the Chenopodiaceae, while palynological data emphasize the close relationship of the betalain families, and support their association with the anthocyanin families.

Ultrastructure of pollen exine in centrospermous families
TLDR
All families have close pollen morphological relationships, with close morphological similarities of the first ten families enumerated above, i.e., those containing betalains. Expand
POLLEN MORPHOLOGY AND THE RELATIONSHIPS OF CIRCAEASTER, OF KINGDONIA, AND OF SARGENTODOXA TO THE RANUNCULALES
The pollen of three monotypic genera, Circaeaster, Kingdonia, and Sargentodoxa has been examined by light and scanning electron microscopy and in the case of the last genus, also by transmissionExpand
Pollen ultrastructure of Panax(the ginseng genus, Araliaceae),an eastern Asian and eastern NorthAmerican disjunct genus.
TLDR
The eastern North American P. trifolius, commonly known as the dwarf ginseng, has a distinctive pollen morphology and exine structure, supporting the hypothesis of its phylogenetically isolated position. Expand
Pollen morphology, exine structure and systematics of Acalyphoideae (Euphorbiaceae) Part 1. Tribes Clutieae (Clutia), Pogonophoreae (Pogonophora), Chaetocarpeae (Chaetocarpus, Trigonopleura), Pereae
TLDR
The data from exine structure of the Euphorbiaceae support the monogeneric concept of Clutieae and show that Pogonophora is not closely related to Clutia, and suggest that Trigonopleura may be more closelyrelated to Pogonphoreae than to Chaetocarpeae. Expand
Pollen morphology, exine structure and systematics of Acalyphoideae (Euphorbiaceae)
TLDR
Characteristics which argue against a supposedly close relationship to Ditaxis and Argythamnia are arguments against the present concept of tribe Pycnocomeae, which is not supported by the pollen data. Expand
Pollen morphology, exine structure and systematics of Acalyphoideae (Euphorbiaceae), Part 4
This is the fourth, last and largest installment of a palynological study of the Acalyphoideae that examined in light, scanning electron and transmission electron microscopy, the pollen of a grandExpand
