Grolle (1989) united Strepsilejeunea subcrenulata Herzog with the younger name Cheilolejeunea papillata Solari. However, transferring the former name to Cheilolejeunea was blocked by the existence of ...the earlier name Cheilolejeunea subcrenulata (Spruce) R.M.Schust. so Grolle used next available name which was Solari's Cheilolejeunea papillata. Unfortunately, the latter name is also a later homonym to Cheilolejeunea papillata (Herzog) Kachroo, which Grolle overlooked. Thus, the taxon is lacking a legitimate name in Cheilolejeunea. Therefore, we here replace the earliest name with a new name in the genus.
Phylogenetic turnover has emerged as a powerful tool to identify the mechanisms by which biological communities assemble. When significantly structured along environmental gradients, phylogenetic ...turnover evidences phylogenetic niche conservatism, a critical principle explaining patterns of species distributions at different spatio–temporal scales. Here, we quantify the contribution of geographic and macroclimatic drivers to explain patterns of phylogenetic turnover in an entire phylum of land plants, namely liverworts. We further determine whether climatic niche conservatism has constrained the distribution of liverworts in the course of their evolutionary history. Two datasets, one insular, focused on 60 archipelagos and including 2346 species, and the second global, including 6334 species in 451 oceanic and continental operational geographic units (OGUs) worldwide, were assembled. Phylogenetic turnover among OGUs was quantified through πst statistics. πst‐through‐time profiles were generated at 1 Myr intervals along the phylogenetic time‐scale and used to compute the correlation between πst, current geographic distance and macroclimatic variation with Mantel tests based on Moran spectral randomization to control for spatial autocorrelation. The contribution of macroclimatic variation to phylogenetic turnover was about four‐times higher than that of geographic distance, a pattern that was consistently observed in island and global geographic settings, and with datasets including or excluding species‐poor OGUs. The correlation between phylogenetic turnover and geographic distance rapidly decayed at increasing phylogenetic depth, whereas the relationship with macroclimatic variation remained constant until 100 Mya. Our analyses reveal that changes in the phylogenetic composition among liverwort floras across the globe are primarily shaped by macroclimatic variation. They demonstrate the relevance of macroclimatic niche conservatism for the assembly of liverwort floras over very large spatial and evolutionary time scales, which may explain why such a pervasive biodiversity pattern as the increase of species richness towards the tropics also applies to organisms with high dispersal capacities.

The first ever liverwort and hornwort checklist is provided for the Maluku Islands (Moluccas/Spice Islands) of Indonesia. We report 355 accepted and 16 doubtful species and reject 22 species ...previously reported for Maluku Islands. The list is based on the specimens housed in the Herbarium Bogoriense (BO) and reports from over 500 literature references, including monographs, regional studies, and molecular investigations. The Maluku Islands are part of the Wallacea Biodiversity Hotspot with many unique species found only in Wallacea. Publications focusing on liverworts and hornworts of Maluku Islands are few and scattered. Considering regionally widespread species that have been recorded elsewhere, we predict that further fieldwork exploring the diversity of habitats coupled with collections unveiled from regional herbaria, a number of new records remain to be reported.

The first ever liverwort and hornwort checklist is provided for the Kepulauan Sunda Kecil (Lesser Sunda Islands) of Indonesia and Timor-Leste (East Timor). We report 129 accepted taxa, 12 doubtful ...taxa and three rejected taxa previously reported for the Lesser Sunda Islands. The list is based on over 130 literature references, including monographs, regional studies, and molecular investigations. It is clear that bryophytes from this region have been overlooked historically, and under collected, compared to seed plants, birds, and other organisms, forming a remarkable gap in the flora of Indonesia. Publications dealing with liverworts of Lesser Sunda Islands are few and scattered. We predict that further fieldwork, in addition to collections unveiled from regional herbaria, will uncover a number of new records that remain to be reported, especially considering that regionally widespread species have been recorded elsewhere.

Kuwahara (1984) synonymized Metzgeria madagassa Steph. and Metzgeria thomeensis Steph. under the name Metzgeria australis Steph. So (2004) rejected this synonymy and recognized Metzgeria madagassa ...from Africa (excluding the syntype from Sikkim) with Metzgeria warnstorffii Steph., Metzgeria camerunensis Steph. and Metzgeria limbatosetosa Steph. as synonyms. Her treatment has generally been followed by subsequent authors of African Metzgeria. However, she overlooked the fact that Metzgeria warnstorffii is the oldest valid name.
