The genus Dendrophorbium occurs in South America with one species known from the Caribbean. Despite recent advances in taxonomy and phylogeny, there is a still lack of molecular studies on the delimitation and identification of the genus. Dendrophorbium is known to occupy a wide range of ecosystems mostly restricted to subtropical montane forests and montane scrub vegetation of the central Andes. In this study, a review of the species occurring in Peru is presented, in addition to material examined at different herbaria. The new combination D. ligulatum which is separated from D. yalusay, and the new species, D. arachnoideum is described from the department of Huánuco in central Peru. The species are assessed using the standards of the IUCN and additional notes are given.
Dendrophorbium 属分布于南美洲，其中一个物种已知产于加勒比海地区。尽管最近在分类学和系统发育方面取得了进展，但在该属的划界和鉴定方面仍然缺乏分子研究。据了解，Dendrophorbium 的生态系统范围很广，主要局限于亚热带山地森林和安第斯山脉中部的山地灌丛植被。在本研究中，除了在不同标本馆考察的材料外，还对秘鲁出现的物种进行了综述。yalusay 分离出来的新组合 D. ligulatum，以及秘鲁中部瓦努科省的新种 D. arachnoideum。根据世界自然保护联盟的标准对这些物种进行了评估，并给出了补充说明。

Corydalis miaotaiensis (Papaveraceae), a new species from the Qinling‐Daba mountains region, central China, is described. It is similar to Corydalis ternatifolia C.Y. Wu, Z.Y. Su & Lidén, but differs from the latter in the crested (versus ecristate) outer petals, unbranched, suberect to erect (versus branched, ascending) stems, bipinnate (versus biternate) rosette leaves, and in the presence (versus absence) of axillary bulbils, long stolons, and long shoots. Corydalismiaotaiensis exhibits a notable growth pattern, initially suberect to erect but gradually transitioning to wholly decumbent with its developed stolons and long shoots, rendering it distinctive within the genus Corydalis. This underscores the need to consider growth habit when describing Corydalis species. An identification key to C. miaotaiensis and related species is provided.
Corydalis miaotaiensis（木犀科）是产于中国中部秦岭-大巴山区的一个新种。它与 Corydalis ternatifolia C.Y. Wu、Z.Y. Su & Lidén 相似，但在以下方面与后者不同：外花瓣具脊（而非糜烂），茎不分枝、近直立至直立（而非分枝、上升），莲座叶为二回羽状（而非二回羽状），以及存在（而非不存在）腋生珠芽、长匍匐茎和长枝。Corydalis miaotaiensis 表现出显著的生长模式，最初是近直立到直立，但随着发达的匍匐茎和长枝，逐渐过渡到完全外倾，使其在 Corydalis 属中独树一帜。这强调了在描述 Corydalis 种类时考虑生长习性的必要性。提供了 C. miaotaiensis 和相关种的鉴定检索表。

In the montane flora of Taiwan, Anaphalis nepalensis is the most widely present species of Anaphalis (Compositae), yet its taxonomic status is uncertain. In the present study, we employed both morphological and molecular data to demonstrate that A. nepalensis is misidentified and does not occur in Taiwan. In contrast, the name has been misapplied in Taiwan to the previously described endemic species, A. nagasawae, which can be further divided into two varieties based on the number of heads in the inflorescence: A. nagasawae var. nagasawae has one or two heads, while A. nagasawae var. niitakayamensis has three to five heads. Furthermore, the typification of A. nagasawae, A. nepalensis and Gnaphalium niitakayamense are discussed here.

The members of the genus Conamomum Ridl. (Zingiberaceae) are primarily distributed from Indochina to western Malesia. Knowledge of the distribution of species of Conamomum is important for conservation and natural resource management. The objective of this review is to comprehensively summarise the morphological characteristics, distribution, ecology, diversity, and potential pharmacological effects of Conamomum species worldwide. The current study also provides a scientific reference for future applications by comprehensively reviewing the literature from 1892 to 2024 via several scientific databases, such as Web of Science, Scopus, Google Scholar, PubMed, Science Direct, Springer, and other online databases. A cluster analysis conducted on 12 species of Conamomum provides valuable insights into their morphological similarities and distribution patterns. Conamomum cylindrostachys and C. flavidulum have anther crests that are horned and 2‐lobed, contrasting with the horned and 3‐lobed anther crests observed in other Conamomum species. Regarding distribution, three species – C. odorum, C. rubidum, and C. Vietnamense – are endemic to Vietnam, while C. spiceum and C. flavidulum are both endemic to Malaysia. A key to species of Conamomum based on the morphology is provided. Extracts and isolated compounds from Conamomum plants, mainly essential oils, have been assessed to possess numerous pharmacological properties, such as anti‐inflammatory, anti‐bacterial, anti‐fungal, anti‐larvicidal, and cytotoxic activities. This review provides valuable insights into the morphological, ecological, and pharmacological properties as well as the diversification of Conamomum and identifies the ecological adaptations specific to their habitat in this region. These findings are valuable resources for conservation efforts, sustainable utilization, and future studies.

We aimed at an inventory of all populations of wild Phaseolus (bean) species in Costa Rica, in relation to future plant breeding. During the field work in 2003–2018, three new and rare bean species (i.e. P. albicarminus, P. angucianae and P. hygrophilus) were found in different montane forest habitats which originally occupy a small acreage. Field observations, together with satellite images, indicate deforestation due to coffee plantations or pastures. To date only eleven populations of these species are known, distributed along the Talamanca and Fila Cruces mountainous ranges, making them endemic. Their narrow distribution, deforestation affecting the original habitats, and occurrence outside established and enforced protected areas motivate the assessment of their conservation status as ‘Endangered' (EN).

Documenting floristic diversity, its natural history traits and habitat affiliation offers crucial insights for developing conservation strategies and management plans for regional biodiversity. In this study, we employed random sampling technique to investigate the floristic composition, natural history trait diversity and habitat distribution among 12 major forest types spread across an elevational gradient of 350–3450 m a.s.l. in the western Himalayan region of Jammu and Kashmir. We recorded 451 species belonging to 90 families in the study region, with herbaceous growth form, perennial life span and therophyte categories dominant. We observed a steady increase in species richness from 800 to 2000 m a.s.l., with highest at 1750 m a.s.l. in the Himalayan dry temperate forest type and then a decreasing trend with elevation. In terms of species turnover, the lowest dissimilarity of 36.8% was found between the Himalayan dry temperate and Fir forests. Whereas, considering species replacement (βsne), the highest similarity of 17.3% was found between the lower western Himalayan and Himalayan dry temperate forests. This shows that beta‐diversity patterns between different forest types are mostly driven by species replacement. Multivariate analysis revealed three major groups in the entire forest species pool. Habitat‐wise, 34% species were recorded in the natural habitats, while the remaining 66% were found in human‐modified habitats (roadsides, piospheres). Our findings will improve scientific understanding of the forest vegetation of this Himalayan region and help in guiding forest policy and management.

Habitat‐wise, 34% species were recorded in the natural habitats, while the remaining 66% were found in human‐modified habitats (roadsides, piospheres). Our findings will improve scientific understanding of the forest vegetation of this Himalayan region and help in guiding forest policy and management.","PeriodicalId":54716,"journal":{"name":"Nordic Journal of Botany","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142191003","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}
