Phenetic relationship between <i>Lepisorus</i> (J. SM.) Ching (Pteridophyta: Polypodiaceae) and its related genera

Multivariate analyses based on morphological and anatomical characters have been performed to investigate the phenetic relationship and to clarify the circumscriptions of the genus Lepisorus (J.Sm.) Ching and its related genera, namely Neocheiropteris Christ, Paragramma T. Moore and Platygyria Ching &amp; S.K. Wu. The dendrogram of cluster analysis separated the plants into three groups at Gower similarity coefficient 0.75. Group 1 and Group 2 consisted of Neocheiropteris palmatopedata (Baker) H. Christ and four species of Platygyria, respectively. Group 3 was Neocheiropteris ensata Ching and two species of Paragramma deeply embedded in the Lepisorus s.s. Canonical discriminant analysis supported the classification inferred from the clustering results. Based on these results, Platygyria and N. palmatopedata should be recognized as distinct genera. On the other hand, N. ensata and the genus Paragramma should be merged to the genus Lepisorus.  Keywords: Lepisorus; Paragramma; Platygyria; Cluster analysis; Canonical discriminant analysis. DOI: 10.3329/bjpt.v16i2.3924 Bangladesh J.

Historical Archaeology, Contact, and Colonialism in Oceania

The archaeology of colonialism can destabilize orthodox historical narratives because of its critical engagement with multiple lines of evidence, revealing ways that different perspectives can complement or contradict what was assumed to be known about the past. In Oceania, archaeology that blends evidence from landscapes, sites, and artifacts with written documents as well as oral traditions reveals the role of indigenous people in shaping colonial encounters across the region over the last five centuries. The challenge lies with how to interpret this material in terms of ongoing struggles over land, resources, and identity in the region today, encapsulated by the tension between global and local
