Primulina guarouba, a new species from the limestone area of northern Guangxi, China, is described and illustrated. According to the maximum likelihood (ML) and Bayesian inference (BI) analysis, it nests in a strongly supported clade (BP = 99%) that includes P. cordifolia, P. repanda and P. huangii. Of these, P. guarouba is similar to the P. cordifolia in morphology, but it is easily distinguished from the latter by some of the distinct characters in leaf blade, peduncles, bracts, calyx, corolla, pistil.
本文描述并说明了中国广西北部石灰岩地区的一个新物种--Primulina guarouba。根据最大似然法(ML)和贝叶斯推断法(BI)分析,它巢居在一个强支持支系(BP = 99%)中,该支系包括 P. cordifolia、P. repanda 和 P. huangii。其中,P. guarouba 在形态上与 P. cordifolia 相似,但通过叶片、花序梗、苞片、花萼、花冠、雌蕊的一些明显特征,很容易与后者区分开来。

Ophiorrhiza paralatiflora, a new species of Rubiaceae from limestone areas of Guangxi, China, is described and illustrated. The new species is morphologically similar to O. alatiflora, but differs from the latter by having an inflorescence that is erect from the youngest developmental stage (versus initially drooping then gradually erect), subulate bract (versus linear or linear‐lanceolate) absent or shorter than 3 mm (versus obvious, 5–15 mm long). It also resembles O. cantonensis, but can be distinguished from the latter by the same characters as from O. alatiflora, plus by having a corolla tube with ca 1 mm (versus 0.3 mm) wide wings outside along its entire length (versus from near apex to the middle part). The conservation status was assessed as ‘Least Concern' (LC) according to the IUCN Red List categories and criteria.
本报告描述并说明了产自中国广西石灰岩地区的茜草科新种 Ophiorrhiza paralatiflora。alatiflora 在形态上相似,但与后者的不同之处在于花序从幼年发育阶段开始就直立(而不是最初下垂然后逐渐直立),钻形苞片(而不是线形或线状披针形)无或短于 3 毫米(而不是明显的 5-15 毫米长)。alatiflora 相同的特征,加上花冠筒全长(从近先端到中间部分)外侧有约 1 毫米(对 0.3 毫米)宽的翅。根据世界自然保护联盟(IUCN)红色名录的分类和标准,该物种的保护状况被评估为 "最不关注"(LC)。

The species are rupicolous, epiphytic, or terrestrial herbs that inhabit humid areas and, occasionally rupestrian fields. In this study, three new species of Peperomia, namely P. ilheusensis, P. itaimbense, and P. mendanhensis, belonging to the subgenus Multipalmata, are described from the Brazilian Atlantic Forest. The descriptions include detailed information, illustrations, distribution maps, and an identification key to species of P. subgen. Multipalmata in Brazil.

Predicting the effect of climate change on the geographic range of the Mediterranean relict tree Liquidambar orientalis Mill 预测气候变化对地中海孑遗树种 "Liquidambar orientalis Mill "地理分布的影响

Climate change is anticipated to pose a significant danger to the habitats and spatial distribution of species in the Mediterranean region throughout the present century. The primary objective of this study was to predict the future geographic range of Liquidambar orientalis, commonly known as the oriental sweetgum under different climate change scenarios. This species is a relict riparian Mediterranean plant originating from the southwestern Anatolia region and Rhodos Island in Greece. To gain insights into the potential effects of climate change on the range of L. orientalis in the future, I used an ensemble modeling approach of species distribution models based on the shared socioeconomic pathways (SSP1‐2.6 and SSP5‐8.5 for the years 2035, 2055 and 2070). The models suggested that the level of precipitation during the wettest month has a crucial role in determining the occurrence of the oriental sweetgum tree. Future projections indicate that the oriental sweetgum will significantly contract its native distribution range due to warming and declining precipitation levels. The population of L. orientalis has previously undergone a decrease as a result of anthropogenic activity. Therefore, it is imperative to augment the degree of urgency in conservation endeavors for the oriental sweetgum species against the ramifications of human‐induced actions and the persistent effects of climate change.
预计气候变化将在本世纪对地中海地区物种的栖息地和空间分布构成重大威胁。本研究的主要目的是预测在不同的气候变化情景下,Liquidambar orientalis(俗称东方甘李)未来的地理分布范围。该物种是一种起源于安纳托利亚西南部地区和希腊罗多斯岛的地中海河岸植物。为了深入了解气候变化对未来东方桉树分布范围的潜在影响,我使用了基于共同社会经济路径(SSP1-2.6 和 SSP5-8.5,2035、2055 和 2070 年)的物种分布模型集合建模方法。这些模型表明,最潮湿月份的降水量对东方桉树的出现起着至关重要的作用。未来预测表明,由于气候变暖和降水量减少,东方甘李的原生分布范围将大幅缩小。此前,由于人类活动的影响,东方桉树的数量已经减少。因此,面对人类活动造成的后果和气候变化的持续影响,加强东方甘李物种保护工作的紧迫性势在必行。

A new species of Melanoleuca subg. Urticocystis with urticiform cheilocystidia is proposed from Lal suhanra National Park, Bahawalpur district, Punjab, Pakistan. The identification is based on morphological characters and molecular phylogenetic analyses using ITS sequences. A comparison of morphological features and molecular phylogenetic data with the known taxa of the subgenus confirms the identity of the species as a new taxon. Detailed descriptions, line drawings and phylogenetic results are presented.

A comparison of morphological features and molecular phylogenetic data with the known taxa of the subgenus confirms the identity of the species as a new taxon. Detailed descriptions, line drawings and phylogenetic results are presented.","PeriodicalId":54716,"journal":{"name":"Nordic Journal of Botany","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140589240","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}
