“…Furthermore, the advantages of SEM in investigating the complex exines of the pollens of the three species had also been assessed in this study due to its high magnification, resolution, and great depth of field. The pollen ultrastructure analysis of other Asteraceae species using SEM had also previously been reported such as of the tribe Barnadesioideae, Cichorieae, and Vernonieae (Zhao et al 2000;Wang et al 2009;Wortley et al 2012;Robinson and Skvarla 2014).…”

Salamah A, Luthfikasari R, Dwiranti A. 2019. Pollen morphology of eight tribes of Asteraceae from Universitas Indonesia Campus, Depok, Indonesia. Biodiversitas 20: 152-159. Asteraceae is one of the largest flowering plant families in the world consisting of a high diversity of species that possess many macro-morphological characters. Ecological pressures have resulted in this highly varied morphology. Our research aims to describe the pollen morphology of the Asteraceae for species occurring in Depok Campus of Universitas Indonesia. Pollens of 14 species from eight tribes were extracted using acetolysis method and observed under a light microscope. The result showed that pollen unity, shape and pollen surface appeared to be differentiating characters of the Asteraceae from other families, while polarity and symmetry characters can be distinguishing characters at higher levels of the family such as subdivisions. Aperture characters were useful to differentiate between tribes. The shape of pores and size of pollen were not useful in differentiating between tribes, but may differentiate between lower taxa. The results of this study could be used as supporting data for regrouping taxa within the Asteraceae using morphological features.

“…Nevertheless, the pollen morphology of the Asteraceae, and especially its ultrastructure has proven to be taxonomically and phylogenetically very useful (e.g., Skvarla and Larson 1965;Keeley and Jones 1976;Skvarla et al 1977;Breitwieser and Sampson 1997;Wortley et al 2008;Pereira Coutinho and Dinis 2009;Wortley et al 2012;Tellería et al 2013). Also, the exine data of Asteraceae are important to understand the fossil pollen record and early history of the family (Muller 1981;Zavada and De Villiers 2000;Tellería et al 2010).…”

The exine morphology, with emphasis on the ultrastructure, of six genera and species of Ecliptinae was studied with transmission electron microscopy and scanning electron microscopy. A caveate exine with a single layer of columellae and predominantly circular to subcircular internal foramina (Helianthoid pattern of structure) is present in all the studied taxa and most probably in all the Ecliptinae. The morphologies of the internal foramina and foot layer are consistent within the Ecliptinae, and their potential taxonomic and phylogenetic relevance was discussed. The existence, for almost all the investigated characters and ratios, of a continuous gradient among the taxa, exists in the wedelioid group and constitutes a quite well defined parallelism between the exine data and those of the major clade of Ecliptinae (wedelioid group). The exine sculpture of the worldwide weed Eclipta prostrata (L.) L. presents some variation, which is, most probably, correlated to the existence of geographical clines and/or variations in its chromosome number. A mesoaperture concerning the foot layer and the upper part of the endexine exists in all the taxa studied and, presumably, in all the Ecliptinae, probably constituting a synapomorphy for all the Asteroideae and possibly for all the Asteraceae.
