En las Américas tropicales, Orthosiinae (Apocynaceae) comprende especies de plantas con flores pequeñas pero complejas y alberga una alta diversidad, aún poco estudiada, actualmente clasificada en cuatro géneros: Jobinia, Monsanima, Orthosia y Scyphostelma. En este estudio, describimos e ilustramos cuatro especies nuevas de Scyphostelma: S. bolivianum, S. gracile, S. rotorum y S. solomonii, con base en especímenes recolectados en Bolivia y Perú. El análisis filogenético ubica a S. bolivianum y S. gracile en un clado con S. harlingii, una especie del sur de Ecuador y el centro de Perú, juntas como clado hermano del resto de Scyphostelma. Debido al tamaño de las flores y a los pedúnculos y pedicelos filiformes largos, consideramos a las dos nuevas especies S. roturum y S. solomonii y la nueva combinación S. erikseniae una parte del grupo S. harlingii, para el cual se presenta una clave de identificación. Además, se lectotipifican cuatro nombres de especies y se realizan seis nuevas combinaciones en Scyphostelma: S. fasciculiflorum, S. jaramilloi, S. purpurascens, S. quitense, S. stenospira y S. unguiculatum.
在热带美洲，Orthosiinae(夹竹桃科)由花小但复杂的植物组成，具有高度的多样性，目前仍很少被研究，目前分为四个属:Jobinia, Monsanima, Orthosia和Scyphostelma。本文以玻利维亚和秘鲁采集的标本为基础，描述和说明了Scyphostelma的4个新种:S. bolivianum、S. gracile、S. rotorum和S. solomonii。系统发育分析将S. bolivianum和S. gracile与来自厄瓜多尔南部和秘鲁中部的S. harlingii归为一个分支，作为Scyphostelma其余部分的姐妹分支。由于花的大小和长丝状花梗和花梗，我们认为两个新种S. roturum和S. solomonii和新组合S. erikseniae是S. harlingii群的一部分，并给出了鉴定关键。此外，选择了4个物种名称和6个新的组合:S. fasciculiflorum, S. jaramilloi, S. purpurascens, S. quitense, S. stenospira和S. unguiculatum。

Abstract: Thirteen species of Friesodielsia Steenis (Annonaceae) and 11 representatives of related genera were included in molecular phylogenetic analyses using up to six plastid DNA regions (psbA-trnH, trnL-trnF intergenic spacers; trnL intron; matK, ndhF, rbcL exons). The results support the recognition of a new species, F. lalisae Damth., Baka & Chaowasku from Narathiwat, S Thailand, as belonging to one of the two major clades of Friesodielsia. The members of this clade show outer petals that separate at anthesis and have a concave basal portion, while members in the other major clade exhibit outer petals that separate early during developmental stages and have a flat base. Friesodielsia lalisae is described and illustrated. It is most morphologically similar to F. argentea (J. Sinclair) Steenis and F. glauca (Hook. f. & Thomson) Steenis but differs from the two by having dissimilar sepal shape, higher proportion of inner petal to outer petal length and longer inner petals. The new species additionally differs from the former by having different leaf base and from the latter by having denser indumentum on young twigs and shorter flowering pedicels. Narathiwat, a province to which the new species is endemic, seems to be one of the most underexplored areas in Thailand as evidenced by a number of species described based on recent material. The conservation status of the new species is provisionally assessed as Critically Endangered.

Abstract: In this study, we provide a new analysis on strict-endemic vascular plant taxa of Algeria and discuss their taxonomic diversity, geographical distribution and conservation status, based on a large literature review and our own field observations. Overall, 248 taxa (species, subspecies and varieties) are currently considered as Algerian endemics, from 41 families and 128 genera. They constitute about 6.3% of the total known flora of Algeria. The northern floristic regions are richer in endemic species: K1, K2, AS3, C1+C2 and O1 are by far the richest floristic regions for strict-endemic taxa, highlighting the importance of their mountain ranges. Most (59%) of the endemic plants have a narrow geographical distribution range (range-restricted). An overview of the IUCN conservation status of the Algerian endemics indicates that only 16 taxa (6.4%) are evaluated, out of which 5.6% of the taxa are threatened. Overall, 44% of the Algerian endemics are legally protected and 43% are included in the protected areas network. Finally, we focus on the shortfalls of knowledge that could orient further research on endemism data in Algeria. They concern taxonomic, chorological or conservation figures and above all the actual presence of the endemic species. It is, therefore, urgent to carry out targeted field expeditions in order to find and re-collect these species, most of which are strictly localized and have probably never been searched or found for 60 years to over a century.

摘要/ Abstract摘要:本文在大量文献回顾和野外观察的基础上，对阿尔及利亚严格地方性维管植物分类群进行了新的分析，并对其分类多样性、地理分布和保护现状进行了探讨。总的来说，248个分类群(种、亚种和变种)目前被认为是阿尔及利亚特有的，来自41科和128属。它们约占阿尔及利亚已知植物群总数的6.3%。北部区区特有物种丰富，K1、K2、AS3、C1+C2和O1是目前严格特有分类群最丰富的区区，突出了其山脉的重要性。大多数(59%)特有植物地理分布范围狭窄(范围受限)。IUCN对阿尔及利亚特有物种保护状况的概述表明，仅有16个分类群(6.4%)被评估，其中5.6%的分类群受到威胁。总体而言，44%的阿尔及利亚地方病受到法律保护，43%被纳入保护区网络。最后，我们关注知识的不足，这些不足可以指导阿尔及利亚地方性数据的进一步研究。它们涉及分类学、时代学或保护数据，最重要的是地方性物种的实际存在。因此，迫切需要进行有针对性的实地考察，以发现和重新收集这些物种，其中大多数都是严格限定的，可能在60年至一个多世纪内从未被搜索或发现过。引用本文:Meddour R Sahar O & Jur S 2023:新疆特有维管植物的多样性、分布格局及保护现状。- wildenwia 53: 25-43记录版本于2023年3月21日首次在线发布，并将于2023年4月出版。

Abstract: Based on analyses carried out with plant material found in mummy shrouds preserved in the archaeological museum El Museo Canario, a putatively extinct new species of Ruta (Rutaceae) was identified and is described here as R. museocanariensis. The mummies were found in the funerary sites of Acusa and the Barranco de Guayadeque on Gran Canaria, Canary Islands, Spain. This article discusses taxonomic relationships with other species of the genus, aspects of colonization and evolutionary processes on islands. The archaeological plant material consists of vegetative and reproductive branches with leaves, remains of flowers and capsules. Several morphological traits, especially the type of fruits, establish a clear difference between Ruta species from Gran Canaria and the mainland (dehiscent) and species from the W Canary Islands (indehiscent). The discovery of R. museocanariensis, with dehiscent fruits, suggests that indehiscence is a post-colonization evolutionary process in the Canary Islands. It also supports a stepping-stone model of inter-island colonization with Gran Canaria as its starting point, in agreement with the age of the islands and to some extent with their distance from the mainland.

摘要：根据对保存在El Museo Canario考古博物馆的木乃伊裹尸布中发现的植物材料的分析，确定了一种被认为已灭绝的芸香属新种，并在这里被描述为R.museocanariensis。这些木乃伊是在西班牙加那利群岛大加那利岛的Acusa和Barranco de Guayadeque的墓地发现的。本文讨论了该属其他物种的分类学关系、在岛屿上的定居和进化过程。考古植物材料包括有叶子的营养和繁殖枝条、花朵和胶囊的残骸。几个形态特征，特别是果实的类型，在大加那利群岛和大陆的芸香属物种（开裂）和加那利群岛的物种（不开裂）之间建立了明显的差异。museocanariensis R.museocanarinsis果实开裂的发现表明，不裂是加那利群岛殖民后的进化过程。它还支持以大加那利群岛为起点的岛间殖民的垫脚石模式，这与这些岛屿的年龄以及在某种程度上与它们与大陆的距离相一致。引文：Marrero RodríguezÁ。，Vidal Matutano P.、Delgado Darias T.、Jaén-Molina R.、Morales Mateos J.、Alberto Barroso V.和Velasco-Vázquez J.2023：与木乃伊一起保存的一种被认为已经灭绝的芸香属新物种的材料能为加那利群岛植物群的进化提供新的知识吗Willdenowia 53:5-23。该记录的版本于2023年2月7日首次在网上发布，随后将收录在2023年4月号中。

The mummies were found in the funerary sites of Acusa and the Barranco de Guayadeque on Gran Canaria, Canary Islands, Spain. This article discusses taxonomic relationships with other species of the genus, aspects of colonization and evolutionary processes on islands. The archaeological plant material consists of vegetative and reproductive branches with leaves, remains of flowers and capsules. Several morphological traits, especially the type of fruits, establish a clear difference between Ruta species from Gran Canaria and the mainland (dehiscent) and species from the W Canary Islands (indehiscent). The discovery of R. museocanariensis, with dehiscent fruits, suggests that indehiscence is a post-colonization evolutionary process in the Canary Islands. It also supports a stepping-stone model of inter-island colonization with Gran Canaria as its starting point, in agreement with the age of the islands and to some extent with their distance from the mainland.
