(Asteraceae, Inuleae) https://oaj.fupress.net/index.php/webbia/article/view/13735 <p class="p1">The genus <em>Berthelotia</em> DC. (presently a synonym of the accepted name <em>Pluchea</em> Cass.), Asteraceae, Inuleae has been regarded as comprising two species, <em>B. lanceolata</em> DC. and <em>B. sericea</em> (Nutt.) Rydb. It honors the French naturalist Sabin Berthelot (1794–1880) for his contribution to the studies of the flora and fauna of the Canary Islands. Under the leadership of Philip B. Webb (1793–1854), Berthelot co-authored the most important work pertinent to the natural history of this archipelago: <em>Histoire Naturelle des Îles Canaries</em>. The nomenclature of <em>Berthelotia</em> and its associated names are revisited here. The holotype of <em>Polypappus sericeus</em> Nutt. (K000974653) was located, and lectotypes were assigned to <em>B. lanceolata</em> (G00450458) and <em>B. lanceolata</em> var. <em>senegalensis</em> DC. (G00452584). Phylogenetic analyses based on nucleotide sequences of the nrDNA ITS were conducted focusing on members of what is known as the Clade J of the Inuleae. A well-supported clade (100% P.P.) that we have labeled as “Clade I” was uncovered, and it is composed of three species that belong to the <em>Pluchea indica</em> Clade plus <em>P. dioscoridis</em> and <em>P. ovalis</em>; but this lineage did not support a previous hypothesis to include <em>P. lanceolata</em>. The two species of <em>Berthelotia </em>did not form a monophyletic group and seem to be distantly related; furthermore, none of these two taxa is sister to <em>Tessaria</em>, a South American genus that has been suggested to be a close relative to <em>Berthelotia</em>. Ethnobotanical uses of <em>B. lanceolata</em> and <em>B. sericea</em> are reviewed.</p> Andre A. Naranjo Rahul R. Pathirickal Kanchi N. Gandhi Piero G. Delprete Riccardo M.

The evolutionary puzzle of Jongkindia (Passifloraceae s.l.), a new monotypic genus and tribe from Liberia, West Africa https://oaj.fupress.net/index.php/webbia/article/view/13470 <p class="p1"><em>Jongkindia</em>, a small tree species endemic to a local area in southeast Liberia, is described as a new monotypic genus of Passifloraceae sens. lat. Its only species <em>Jongkindia mulbahii</em> combines floral characteristics of the Turneraceae and fruit characteristics of the Passifloraceae s.s. (or subfamily Passifloroideae in APG) and can therefore be regarded to occupy an isolated morphological position. This is confirmed here by DNA sequence-based phylogenetic analyses including most Passifloracean genera, which places it as sister to Passifloroideae. We delineate 16 morphological characters and their states and optimise them on our reconstructed phylogenetic tree.<span class="Apple-converted-space">&nbsp; </span>Based on these results we consider the Passifloraceae fruit characteristics (berries with arilled seeds) as synapomorphic for Passifloroideae. The monotypic<span class="Apple-converted-space">&nbsp; </span><em>Pibiria</em> and <em>Jongkindia</em> are predominantly characterised by autapomorphies. On the other hand, the <em>Adenia</em>/<em>Passiflora</em> clade is characterised by polymorphisms. We place <em>Jongkindia</em> in a new tribe Jongkindieae Breteler &amp; F.T.Bakker. A draft plastome sequence for <em>Jongkindia mulbahii</em> is presented and evidence for two mitome to plastome (mtpt) fragment transfers is discussed. Structurally the <em>Jongkindia</em> plastome appears similar to that of <em>Populus</em>, <em>Adenia</em>, <em>Mitostemma</em>,<span class="Apple-converted-space">&nbsp; </span><em>Dilkea</em>, and <em>Passiflora pittieri</em>, but not to contain the previously-described major inversions within other, more derived, <em>Passiflora</em> plastomes.</p> Frans J.

The new species is unique because of the combination of petiolate linear leaves with revolute margins, reticulodromous venation, and 3–5 florets per capitulum. The new species is compared to a morphologically similar species, <em>L. villosissima</em>, resembling in habit, leaves, venation, and number of florets per capitulum, but differing by the shape and size of the leaf and petiole. Both species may occur sympatrically, but are uniform in their morphology with diagnostic features that differentiate them.

This species is also morphologically similar to the continental Asian <em>Wurfbainia microcarpa </em>but can be distinguished from this by the entire ligule, petiolate lamina, congested rachis, and presence of red stripes at the base of the labellum. Therefore, we here describe <em>Wurfbainia rubrofasciata </em>providing colour plates, data on phenology, distribution, habitat, and a provisional conservation assessment. A key to five species of <em>Wurfbainia</em> in the Philippines is provided and we discuss the likely closest relatives of <em>Wurfbainia palawanensis.</em></p> Rudolph Valentino A.

Twenty-seven fern species were examined and valuable qualitative and quantitative data were obtained to generate UPGMA dendrogram. A dichotomous key differentiating the taxa was prepared. Results reveal that even though species have overlapping characters, certain specific traits prove taxonomically valuable. The results proved that traits like leaf shape, higher order leaf venation, stomatal and epidermal features are indeed important diagnostic characters and hence can be used for the identification of fern species in their immature stage or even in absence of sori. These data sets often combined with other morphological as well molecular data would contribute to fern phylogenetic study particularly of the large and complex family Polypodiaceae.</span></p> Sinjini Mondal Saurav Moktan Copyright (c) 2022 Sinjini Mondal, Saurav Moktan https://creativecommons.org/licenses/by/4.0 2022-12-15 2022-12-15 77 2 285 305 10.36253/jopt-13570 Evaluating the species distribution patterns of the genus Saurauia Willd. in the Philippines using geospatial analysis https://oaj.fupress.net/index.php/webbia/article/view/13193 <p class="p1">Understanding the species distribution patterns of endemic and threatened species is very useful for conservation planning and actions. However, research on the distribution of many important and often overlooked species in the country, such as the <em>Saurauia</em>, is extremely limited. This paper provided an overview of the distribution patterns of <em>Saurauia</em> species across the Philippine archipelago based solely on the existing digital checklist of vascular plants. Specifically, the study produced distribution maps of the 56 endemic <em>Saurauia</em> species and determined their climatic distribution ranges. The methods involved geospatial and geoprocessing analysis in a geographic information system (GIS) environment. The findings showed that 29 <em>Saurauia</em> species are currently distributed in a single province, whereas seven (7) species have only been recorded in a certain region. Furthermore, 35 species was found to have a single type of climate. The <em>Saurauia</em> species identified in this paper that have only a single provincial or regional distribution record and are restricted to a single type of climate are recommended for conservation because they are mostly likely to be affected by environmental and climatic changes. Finally, the information and data derived in this paper could serve as a baseline for assessing conservation status, habitat modelling studies, species-level conservation planning, and understanding climate change impacts.</p> Bernard Peter O.

Recent fieldwork in Zamboanga region, Mindanao, Philippines, resulted in the collection of a ginger, which we identified as <em>Burbidgea nitida</em>. The species, however, was already collected in Zamboanga region in 1919 but the evidence remained misidentified for a long time as <em>Hedychium</em>. Including the <em>Burbidgea</em> in the flora of the Philippines, increases the number of native ginger genera of the country to 17. Based on the recent collections, a complete description of <em>B. nitida</em> in the Philippines is provided here including illustrations and notes on ecology and a local name. We lectotypify <em>Burbidgea nitida</em>, the type of the genus, and clarify the overlap of native ginger genera and species between Borneo and Philippines.</p> Kean Roe F. Mazo Rudolph Valentino A.

For long-continuity plant communities, such as ancient woodland, these records may be particularly important for present day ecological management. To evaluate this potential, searches for pre-1950 Ancient Woodland Indicator (AWI) herbarium specimens collected in East Gloucestershire, UK, were conducted using digital open access sources and the physical Royal Agricultural University herbarium. In total 305 specimens were retrieved from twelve herbaria, with small regional collections being particularly important sources. The earliest specimen dated to 1834. There was a significant association between old specimen availability and year of collection, due to a peak in the late-1800s and early-1900s. Over half of the AWI species for the region were represented, although some taxonomic bias was evident. To determine if old AWI specimens contributed any new location records, 246 unique specimens with detailed georeferences were mapped and compared to the locations of 1950-1999 and 2000-2021 biological records. One third of the pre-1950 specimens had not been recorded in the same locality since collection of the old specimen, indicating either a gap in recent records or floristic change. However, length of time since specimen collection was not a predictor of a 1950-2000 or 2000-2021 record in the same locality. Overall, it is highly recommended that policy-makers, land managers, and field surveyors consult old AWI herbarium records for ancient woodland identification, management, and restoration.</p> Kelly Hemmings Copyright (c) 2022 Kelly Hemmings https://creativecommons.org/licenses/by/4.0 2022-12-15 2022-12-15 77 2 327 336 10.36253/jopt-13400 Index of New Taxa https://oaj.fupress.net/index.php/webbia/article/view/14078 <p class="p1">Index of New Taxa</p> Riccardo M.
