“…Seed coat ultra‐structural features using SEM play important roles in the classification and phenetic linkages of species and practical features to study systematic relationships in variety of families, whereas seed micromorphology has proven importance in certain cases (Koul, Nagpal, & Raina, ; Rashid et al, ; Yoshizaki, ). Seed coat and their structural features are successfully applicable in evolutionary relationships and in addition simplify the affiliation among different genera and species within the tribe (Ghimire et al, ). SEM discloses seed outer surface characters that are successfully applicable to solve phylogenetic relationships and the systematic problems (Karihaloo & Malik, ).…”

“…Thus, macromorphological characters like shape and colour does not reflect the generic delimitation in tribe Nigelleae. Also Ghimire et al (2015). found these characters less significant for the generic taxonomy of Ranunculaceae subfam.…”

“…In addition, seed coat morphology, especially micromorphology, have provided useful taxonomic information for different genera of Ranunculaceae (Cappelletti and Poldini 1984, Karcz and Tomzcok 1987, Luo et al 2005, Dadandı et al 2009, Wang et al 2009, Antkowiak et al 2010, Emadzade et al 2010, Heiss et al 2011, Ghimire et al 2015, 2016. Half of the sections of Consolida (Constantinidis et al 2001) and tribe Delphinieae (Ghimire et al 2015) are well supported based on only seed characters. In contrast, seed morphology of Thalictrum L. shows low taxonomic value at the sectional level (Ghimire et al 2016).…”

“…A number of angiosperm taxa have already been intensively investigated in terms of seed morphology, in combination with phenetic or phylogenetic analyses at the genus level. In the past the variation in seed morphology has been used variously in plant systematics ranging from identification (Sako et al 2001, Khalik andVan der Maesen 2002) and taxonomic circumscription (Constantinidis et al 2001, Mendum et al 2001, Amini et al 2011, Sadeghian et al 2014, Ghimire et al 2015a, 2016a, Arabi et al 2017) to phylogenetic inference (Hufford 1997, Arambarri 2000 and character-state evolution (Fukuhara 1999, Simons andHedin 1999). Although quite a few embryological, floral, and carpological studies of Oleaceae have been carried out (Rohwer 1993, 1994, Sher and Weber 2009, Dadpour et al 2011, Naghiloo et al 2013, Ghimire and Heo 2014, Ghimire et al 2015b, studies on comparative seed morphology and seed coat anatomy are still scarce for the family.…”
