In pollen terminology, an operculum is an area of exine covering a pollen aperture like a lid. Monosulcate‐operculate, pontoperculate, disulculate, disulcate, zonasulculate, and zonasulcate aperture types are often confused in the monocot pollen literature. Various factors contribute to this confusion, including the existence of intermediate forms. Other factors include the presence of artifacts (such as the collapse of thin‐walled pollen examined using SEM) and insufficient data, either on… 

Comparative Structure and Development of Pollen and Tapetum in Pandanales

New data and a review of pollen morphology, microsporogenesis, and tapetal characters in Pandanales in a systematic context are presented and apparently homoplastic trends in each family toward either reduction in aperture size or covering the aperture with exine are reported.

The zona-aperturate condition may be a functional benefit in wet environments: while in dry pollen the apertural ring is completely closed, in wet or very moist realm it expands greatly, and the pollen tube can be formed quickly and everywhere in this area.

Developmental and ultrastructural characters of the pollen grains and tapetum in species of Nymphaea subgenus Hydrocallis

The aperture, pollen wall ultrastructure, and the tapetum of the studied species are discussed in an evolutionary and systematic context, and these characters are also compared with those of other angiosperm lineages.

Diaperturate pollen in submerged aquatic monocots Althenia orientalis and Althenia filiformis (Potamogetonaceae: Alismatales)

Abstract Reports on whether typical apertures occur in pollen of Althenia (Potamogetonaceae) are controversial. The question is of interest because relatively few submerged aquatic angiosperms

Pollen structure and function in caesalpinioid legumes.

There is potential to utilize pollen characters to estimate pollination systems where these are unknown and at the species level, there is a potential correlation between striate/verrucate patterns and vertebrate pollination.

Exine micromorphology and ultrastructure in Neottieae (Epidendroideae, Orchidaceae)

The results showed that differences in exine micromorphology are mostly concordant with phylogenetic relationships in Neottieae, i.e. an ascending tendency of pollen ornamentation from tectate (Cephalanthera) to semitectate (e.g. Neottia), which could help to reduce pollen damage caused by exposure to dry habitats.

Pollen Morphology of the Turkish Romulea Maratti (Iridaceae)

Pollen morphology of the Turkish Romulea Maratti taxa (Iridaceae) was examined using light and scanning electron microscopy and the existence of pollen type variability from single pollen sacs was recorded for the first time.

Pollen Evolution in the Early‐Divergent Monocot Order Alismatales

Phylogenetic mapping of pollen and tapetum characters demonstrates that Alismatales are characterized by a potential synapomorphy: a plasmodial Tapetum, a character shared with Acorus and probably other potential outgroups.

Aperture evolution in Nymphaeaceae: insights from a micromorphological and ultrastructural investigation

The hypothesis of an opercular origin of the distal part of the pollen grain in the core Nymphaeaceae is reinforced and support the paraphyly of the genus Nymphaea as emerged from recent molecular studies.



Pollen Ultrastructure of the Tecophilaeaceae

Six genera of the Tecophilaeaceae, which are palynologically similar in having monosulcate, heteropolar, generally foveolate (rugulose in one genus) pollen grains with a tectatecolumellate exine architecture and an operculate aperture, are studied.

Triporate pollen in the Arecaceae

The well-defined, regularly spaced, circular porate apertures that occur in Arecaceae: Areca klingkangensis from Borneo, and species of the West African genus Sclerosperma, appear to be unique in monocotyledons.

Pollen aperture morphology in Arecaceae: Application within phylogenetic analyses, and a summary of record of palm-like pollen the fossil

The systematic rarity of most palm aperture types places limitations on their value in cladistic analyses, but certain aperture characters are of value, and do contribute to a better understanding of the evolution and phylogeny of the Arecaceae.

The convergent evolution of exine shields in angiosperm pollen

The term “clypeate” is proposed for this pollen type, i.e. “pollen grains with large, isolated, polygonal or circular (s)exinous shields, separated by grooves”, which differs markedly from the aperture condition which is present in all of the other taxa investigated.

Phylogenetic trends in the Alismatales with reference to pollen grains

Monosulcate pollen is clearly primitive in the order, as amongst monocotyledons in general, whilst derived pollen grains possess higher numbers of pores.

Pollen ultrastructure of the Pontederiaceae

Pollen of eight genera and species of the Pontedcriaceae was investigated using SEM and TEM to elucidate interrelationships to other monocot families and only members of the tribe Haemodorea were presumed closely related to the Pontederiaceae.

Pollen morphology of Dioscorea (Dioscoreaceae) and its relation to systematics

Pollen morphology strongly supports section Enantiophyllum as a monophyletic group and the results indicate that pollen characters may be significant in infrageneric systematics in Dioscorea.

Pollen Ultrastructure of the Philydraceae

Pollen morphology, sculpturing, and wall ultrastructure of the five species in the monocot family Philydraceae were investigated in order to assess phylogenetic relationships, and Histochemical tests of Philydrum lanuginosum suggest that the outer intine layer is primarily cellulosic and the inner intine layers is pectic-rich.

Morphology of pollen and orbicules in some Dioscorea species and its systematic implications

The results indicate that pollen data may be significant at sectional rank and the close relationship between sections Astemtricha and Enantiophyllum proposed by I3urkill and Ayensu is supported by pollen morphology.
