Whereas 17 Hiptage species have been reported from Vietnam, there is currently no available genetic information that could be used to confirm the species diversity in the country. Through a study combining phylogenetic and morphological analyses of newly-collected samples and herbarium specimens, we were able to accurately identify five Hiptage species in Vietnam. One of these, Hiptageaptera, represents a species new to science. Specimens of the new species show white to slightly pink petals, erect to forward-curved petals, eight tiny calyx glands and wingless fruits, a unique feature within this genus. Our results strongly support Vietnam as one of the diversity centres of the Hiptage genus with 18 species out of the 48 species. Although we could not determine the source of introduction of Hiptage in the Mascarenes Archipelago, our findings highlight the genetic similarity of all Hiptagebenghalensis samples collected in its secondary distribution areas, suggesting a probable single introduction. This is consistent with historical reports dating the plant's introduction to the Mascarenes to the 18th century.","PeriodicalId":20070,"journal":{"name":"PhytoKeys","volume":"256 ","pages":"221-238"},"PeriodicalIF":1.3,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12149886/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144267026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The leaves of C.hekouensis contain 1.18 mg/g theobromine, which disagrees with the previous chemotaxonomic claim.

With the advancement of molecular biology in recent years, the classification of this genus has undergone significant changes, revealing several morphologically indistinguishable cryptic species. In this study, we collected species of Erythrotrichia from the Bohai Sea coast of China, proposed a new species-Erythrotrichiabohanensis sp. nov. based on laboratory culture, morphological observation and molecular phylogenetic analysis. Phylogenetic analyses, including rbcL and SSU gene sequence analyses, demonstrated that Erythrotrichiabohanensis sp. nov. clusters into an independent branch with high Maximum Likelihood (ML) bootstrap values and Bayesian Inference phylogenies (BI) posterior probabilities. The new species is characterized by an unbranched, filamentous thallus and exhibits both asexual and sexual reproduction. The main morphological differences of the new species are primarily reflected in its sexual reproduction process. The carpogonium and spermatium are formed by the expansion and division of vegetative cells, and fertilization occurs outside the thallus. The establishment of this new species underscores the cryptic species diversity within this taxon and implies that additional morphological, molecular, and genetic information is essential for more precise species identification.","PeriodicalId":20070,"journal":{"name":"PhytoKeys","volume":"256 ","pages":"175-184"},"PeriodicalIF":1.3,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12142218/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144249196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prolification refers to the development of a vegetative bud from the axil of a bract within the floral meristem, a frequent condition in the Pleurothallidinae, where it manifests as a new ramicaul developed from the apex of a previous ramicaul. Prolification can be either constitutive or facultative, the latter occurring mostly under stress-induced, non-optimal growing conditions. The three new species are found at high elevations, between 1400 and 2550 m, in humid, dense, mossy conditions on the Talamanca range, where they naturally produce prolific growths on the ramicaul apex that sever from the plant with time. Pleurothallismatrisilvae sp. nov. superficially resembles P.bothros, but may be distinguished by the prolific habit, thin ramicauls, typically bearing 1-2 open flowers, the longer flower segments, the lanceolate petals, and the black flecks on the pedicel, ovary, and external surface of the sepals. Pleurothallispridgeoniana sp. nov. is similar to P.vinealis but distinguished by the significantly shorter plants and ramicauls, the much smaller yellow flowers with a rose to purple suffusion, and the triangular-ovate lip with glandular margins and lacking a central sulcus. Pleurothalliswinkeliana sp. nov., closely resembles P.longipetala, but differs by the occasionally prolific plant that produces clumps of ramicauls, the comparatively broader, cordate leaves with overlapping basal lobes, the smaller flower, and the pendent lip, perpendicular to the column.","PeriodicalId":20070,"journal":{"name":"PhytoKeys","volume":"256 ","pages":"197-220"},"PeriodicalIF":1.3,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12142217/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144249199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(heathers; anjavidy in Malagasy) has 35 recognised species in Madagascar, but there has not been a taxonomic revision since 1927 and there are few identification resources. We review available data for Malagasy Erica (previously treated as Philippia), summarise diagnostic species descriptions and incorporate them into the Erica Identification Aid. There is clearly variation in current species concepts that requires further study. Malagasy Erica most likely represent a single clade also encompassing species from the Mascarenes, but resolution is poor and most species remain unsequenced. Erica is found in several of Madagascar's ecosystems, including the high-altitude \"ericoid thickets\" where diversity is highest, but it is absent from the extensive dry western areas. Habitats include the ericoid thickets, shrubland-grassland mosaics in the central highlands and on the eastern coast, and Uapacabojeri (tapia) savanna. Many Erica species are likely to be part of dynamic ecosystems with infrequent fire regimes. The palaeorecord indicates a more widespread ericoid shrub vegetation during the last glacial period. There may be both wind- and insect-pollinated species. Erica is mainly used as fuelwood in Madagascar, but local uses as tools and medicine have also been reported. Estimates suggest at least one-fifth of the species may be threatened, but formal assessments are lacking. Taxonomic revision of the group, coupled with phylogenomic, ecological and ethnobotanic studies, is an urgent priority.","PeriodicalId":20070,"journal":{"name":"PhytoKeys","volume":"256 ","pages":"91-118"},"PeriodicalIF":1.3,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12117345/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144174523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
