Baryandra from Tanauan City, Batangas, southern Luzon, Philippines. Morphological data shows this species resembles B. chingipengii, a species from eastern Luzon as both species have light pink flowers, fleshy green lamina, and boat-shaped bracts. However, B. tanauanensis does not have the prominent white midrib and veins in the adaxial leaf surface, ciliate hairs on leaf margin, strongly keeled stipules and tomentose hairs on the abaxial leaf surface and petioles of B. chingipengii. The plants were observed to have a restricted and severely fragmented distribution. Unfortunately, these observed populations are also affected by human activities and threat of volcanic activity of the nearby Taal Volcano. Because of these threats, we provisionally assess the species as “Critically Endangered” (CR) following the IUCN Red List Categories and Criteria.","PeriodicalId":20114,"journal":{"name":"Phytotaxa","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140223465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Callipteris seshufenensis has a remarkable morphology characterized by a narrow midvein with distinct transverse stripes, small pinnules with 2–3 lateral branches directly connected with pinna-rachis except for the rounded-obtuse apex of pinnule and costule divided more than three times (sometimes more than five times).

The species was described in the 1990s based on two samples from the municipality of Linhares. Subsequently, other materials were identified as belonging to the species. However, this set of materials exhibits heterogeneous morphology, which raises doubts about the correct name application. Therefore, it was necessary to expand the species description by incorporating new field-collected data and analyzing a greater number of herbarium specimens. In this study, we analyzed materials deposited in herbaria identified as P. renatiana, reviewed the literature, and conducted field surveys. Based on the collected data, we have expanded the morphological description and reassessed its extinction risk. In addition to the morphological description, taxonomic comments, phenology, a distribution map, and illustrations are provided. In our reassessment, the species was categorized as EN (A2c; B1(i,iii,v) + 2ab(ii,iii,v)), with changes to the criteria used in the 2012 assessment. Despite the review and inclusion of new data, the species has remained in the same threat category in which it was assessed more than a decade ago, underscoring the need for conservation efforts.","PeriodicalId":20114,"journal":{"name":"Phytotaxa","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140226583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Iberian Peninsula is a major phylogeographic hotspot for oak diversity, with almost all possible combinations of hybrids already described inside sect. Quercus.

We provide a description of this nothotaxon (which we named Quercus ×gaonae) based on morphological characters related to leaf shape and trichome analysis.
