“…Variations in the number and arrangement of apertures have been reported as the most common type of variation within the eudicots (Ressayre et al 2002;Fukuda et al 2008;Golshan et al 2014), which can occur at the population level (polymorphism) or at the individual level (heteromorphism) (Walker and Doyle 1975). In this study, aperture variations were observed to be restricted to the individual level.…”

Asia, especially the temperate Sino-Himalayan region is one of the four major diversity centers of Indigofera. Pollen morphology of Indigofera species in the Sino-Himalayan region is poorly known. In this study, pollen morphology of 52 samples representing 43 Chinese Indigofera species and two varieties was examined using scanning electron microscopy to evaluate its taxonomic significance. Parasyncolpate pollen grains were described in Indigofera for the first time. Cluster and principal component analyses were conducted based on four quantitative and three qualitative pollen characters. Five groups were recognized within Chinese Indigofera in the cluster analysis, but only one can be separated by the first three principal components. The shape and size of pollen grains in Indigofera are highly variable. Consequently, both the characters lack any significant taxonomic value. The number of apertures, tectum architecture and perforation density shows some taxonomic significance. The pollen morphology exhibits obvious phylogenetic and biogeographical significance on large scales in Indigofera. Although pollen characters alone are insufficient to reconstruct the taxonomic relationships within Indigofera, palynological data can provide some useful information for the species-level revisions.

“…showed that they are characterised by high variability, both inter-and intra-specific, as well as in relation to oligo-and polyphagous species parasitic on various hosts. In addition, some taxa may produce heteromorphic pollen grains (Zare et al 2013), but this issue requires further study. Surely pollen characteristics, i.e.…”

“…Unfortunately, there are still not many papers dedicated to the pollen morphology of the family Orobanchaceae (e.g. Tiagi 1951;Rao 1963;Erdtman 1966;Polo 1987;Minkin and Eshbaugh 1989;Teryokhin 1997;Shahi Shavvon and Saeidi Mehrvarz 2010;Zare and Dönmez 2013;Zare et al 2013;) and further studies within the whole family are required.…”

Pollen morphology of the Central European broomrapes (Orobanchaceae: Orobanche, Phelipanche and Orobanchella) and its taxonomical implications

Pollen grains of 450 samples of 25 species of the genus Orobanche and Phelipanche occurring in Central Europe were investigated using light and scanning electron microscopy. Palynological data on 18 species are reported here for the first time. The usefulness of micromorphological studies on pollen of Orobanche and Phelipanche is demonstrated. Previous research showed the separation of Phelipanche from Orobanche, a finding which is also supported by pollen aperture type and exine ornamentation. The pollen of Phelipanche is tricolpate, while that of Orobanche is inaperturate. Our research showed that one of the species included so far within Orobanche, namely O. coerulescens, has tricolpate pollen with microreticulate sculpture. As a consequence of the finding of tricolpate pollen and intermediate macromorphological characteristics of this species between Orobanche and Phelipanche, it is proposed to transfer it to a new genus, Orobanchella, described in the paper. A comparison of the main characteristics distinguishing Orobanche, Phelipanche, Boulardia and Orobanchella is also presented and discussed.

The genus Sophora (Fabaceae) is one of the taxonomically challenging genera with high economic and medical values. In this study, the pollen morphology of 43 samples of 27 species, 4 subspecies, and 4 varieties of the genus Sophora and 3 closely related genera was examined using scanning electron microscopy to evaluate the pollen diversity of the genus and its taxonomic significance. Pollen grains of the studied species were tricolporate (rarely six‐aperture), and pollen shape varied from suboblate, spheroidal, subprolate to prolate. Echinate external ornamentation was reported for the first time in some species of the genus. Aperture membrane ornamentation and outline in a polar/equatorial view were described for the first time in the genus. Principal component analysis was used to understand the relationship and discrimination between the species and the genera, with six components accounting for 79.92% of the total variance. Taxonomic keys based on pollen morphology were also constructed to easily identify the taxa of the genus through palynological characteristics. Results showed that pollen morphology alone is not sufficient to elucidate or reconstruct taxonomic relationships within the genus Sophora, but palynological assessments can provide some useful information for identifying taxonomically problematic taxa.
