The genus Onosma is a homogeneous taxon with high morphological variation and due to the similarities among taxa, there are many problems in their identification. Hence, systematically taxonomically, it considered difficult genus. In present study, we included large number of species throughout distribution range. Using nuclear (ITS) two plastids (rpl32-trnL(UAG) trnH-psbA) markers, analyzed ev...

Abstract— The Lathberry Clade includes seven species of Eugenia sect. Umbellatae (Myrtaceae) distributed from Puerto Rico through the Lesser Antilles. Members are trees and shrubs distinguished other Antillean by a combination dull twigs, glabrous leaves with raised midvein, glomerate or fasciculate inflorescences predominantly borne below on old wood, closely spaced ascending inflorescence bra...

In this study, 3 haplotypes were found in populations of Phellodendron amurense based on two combined cpDNA regions (psbA-trnH and trnT-trnL). Nucleotide diversity haplotype 0.43×10 -3 0.41, respectively at the level species. The AMOVA revealed that only 8.53% variation was explained by differences among geographical groups, whereas inter-population intrapopulation 18.32% 71.35% variation, resp...
