Taxonomic Studies on Some Members of the Genus <i>Abutilon</i> Mill. (Malvaceae)

Abstract

The relationship between six Abutilon species was examined using different taxonomic investigation tools. The investigation was carried out using morphological and numerical studies. Fresh materials of Abutilon species were collected from different localities in Saudi Arabia during 2018 and 2019. Numerical analysis was based on the Principle Coordinates, the Principle Component and the Unweighted Pair Group Method with Arithmetic Algorithm Clustering. The results indicated that there were significant differences based on the morphological characters especially in the leaves, fruits and flowers features. Morphometric studies revealed that the six species of Abutilon clearly separated in all different analysis.

Taxonomy and nomenclature of Abutilon albidum (Malvaceae, Malvoideae), a cryptic Saharo-Canarian species recently rediscovered in Tenerife

“…These two species share all characters, except that their mericarps are ornamented in different ways. Since mericarp ornamentation is considered to be an important diagnostic trait in the genus ( Alzahrani et al 2021 ), both species are apparently distinct. Besides these morphological differences, the species also seem to differ ecologically and occur in non-overlapping areas (see below).…”

Morphological variations of superior sugarcane cultivars (Saccharum officinarum) from Lampung, Indonesia

“…The combination of cluster analysis and principal component analysis has been widely applied in plant systematic studies in various taxa at the taxonomic level, starting from the species level (Fitriana and Susandarini 2019;Singh et al 2020), genus level (Alzahrani et al 2021), and family level (Arogundade and Adedeji 2019). Our study suggests that grouping based on morphological characters as taxonomic evidence is very good for identifying and analyzing local sugarcane cultivar variations and knowing the closeness of their kinship relationships.…”

Testing the susceptibility of larval stages of Simulium to temephos and Bacillus thuringiensis var israelensis in Germany and Northern Cameroon

“…The aligned amino acid was then back-translated to nucleotides, retaining the codon positions. The evolutionary history was inferred using the UPGMA method (Alzahrani et al, 2021). The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree (Figure 8).…”
