Pollen ultrastructure of the biovulate Euphorbiaceae, including the subfamilies Phyllanthoideae and Oldfieldioideae, was investigated with light, scanning electron, and transmission electron microscopy. Pollen of Phyllanthoideae, represented by 12 species in nine genera, was prolate to oblate, almost always 3-colporate, rarely 3-porate or pantoporate, and mostly with reticulate, rarely baculate, echinate, or scabrate, sculpturing. The ektexine showed little variation in ultrastructure; almost… 
Pollen morphology of the Flueggeinae (Euphorbiaceae, Phyllanthoideae)
TLDR
A total of 129 species from the subtribe Flueggeinae of the tribe Phyllantheae were investigated using light and scanning electron microscopy, in order to evaluate the relationships between the eight constituent genera.
Taxonomic significance of sporoderm structure in pollen of Euphorbiaceae: Tribes Plukenetieae and Euphorbieae
TLDR
In general, pollen of the Euphorbiaceae has a thick and well-developed intine, but the more specialised apertural structure, described for tribe Euphorbieae, supports the circumscription of this tribe.
Phylogenetic Implications of Pollen Ultrastructure in the Oldfieldioideae (Euphorbiaceae)
The pollen structure of members of Euphorbiaceae subfamilies Oldfieldioideae and Phyllanthoideae was studied using scanning and transmission electron microscopy in order to assess taxonomic
The pollen morphology of Phyllanthus (Euphorbiaceae) section Choretropsis
TLDR
The results suggest that pollen grain morphology, in association with plant architecture and the presence of phylloclades, constitute additional evidence to delimit the species of the section Choretropsis and to further understand their evolutionary origin within the genus Phyllanthus.

Phylogenetic Relationships of Didymocistus and Hymenocardia ( Euphorbiaceae ) Author ( s ) :
TLDR
The pollen exine wall of Hymenocardia lacks the microchanneled tectum, granular interstitium, and thin foot-layer of the Urticales, but has many palynological features found in the Phyllanthoideae and should be retained in the Euphorbiaceae in that subfamily.
Female flowers and systematic position of Picrodendraceae (Euphorbiaceae s.l., Malpighiales)
TLDR
Floral structure supports the close relationship of Picrodendraceae with Phyllanthaceae and Euphorbiaceae s.str.
Evolution of Angiosperm Pollen. 6. The Celastrales, Oxalidales, and Malpighiales (Com) Clade and Zygophyllales1
Abstract Analyzing pollen morphological data on a contemporary phylogenetic framework can enhance our understanding of the distribution, diversity, and evolution of palynological characters. In
SEM investigation of pollen from the lower Eocene (Carinthia and Salzburg in Austria and Brixton, London area, in England): new findings of Vitaceae, Euphorbiaceae, Phyllanthaceae, Fabaceae, Anacardiaceae, Araliaceae and Apiaceae
TLDR
The earliest known occurrences of pollen of “Bernardieae clade” type, Cephalocroton, unknown Euphorbiaceae/Phyllanthaceae taxon, Flueggea, Bischofia, “Millettioid clade" type, Anacardium, Gluta, Aralia and Panax types in the fossil record are presented.

A Palynological Study of Crotonoideae (Euphorbiaceae)
TLDR
In both morphology and exine structure, the pollen of Crotonoideae closely resembles the (porate) pollen of Thymelaeaceae.
Systematics of Paradrypetes (Euphorbiaceae)
TLDR
The morphology of Paradrypetes, particularly of its leaves and pollen, suggests that this genus is a primitive member of that subfamily of Euphorbiaceae, and its closest relative appears to be Podocalyx, in the tribe Podocalyceae, but numerous differences between these genera justify placing it in its own subtribe.
Notes on Madagascan Euphorbiaceae. III, Stachyandra
TLDR
Whilst working through a pile of undetermined material at the end of the Euphorbiaceae in the Kew Herbarium in 1964, my attention was drawn to two specimens, one sterile and one fruiting, collected by the Rev. R. Baron in northern Madagascar, which had nothing whatever to do with Croton.
Systematics of Croizatia (Euphorbiaceae)
TLDR
The pollen morphology of Croizatia suggests a possible relationship with the Oldfieldioideae, and it may be the closest extant taxon to a connecting link between the subfam- ilies.
Pollen morphology of the Euphorbiaceae with special reference to taxonomy
TLDR
The morphology of the pollen grains of the Stenolobeae is in agreement with the opinion of PAX, that any separation of these Australian genera is an artificial one.
The Identification of some Tertiary Pollen belonging to the Family Euphorbiaceae

TLDR
Five fossil pollen forms from Tertiary assemblages in southern New South Wales are shown to have botanical affinities with taxa in the family Euphorbiaceae, and an analysis of the exine stratification and the base of the spine is a reliable way of distinguishing spiny pollen of the EuphorBiaceae from that of the Malvaceae.
