Summary: The paper reports the discovery of the Southern African endemic Ruschia uncinata (L.) Schwantes (Aizoaceae) along the Mediterranean coastline on cliffs at Monastir in Tunisia (CE Tunisia, N-Africa). This is the first record of this species in this area. The population of R. uncinata, appears to be well-established and expanding. The large number of accompanying alien species suggests that the population of R. uncinata could have originated from dumped garden debris. Description of the morphology, distribution as well as habitat is provided.

Summary: The genus Lithops (Aizoaceae; Ruschioideae) is widely distributed across South Africa, Namibia and into Botswana. Using the environmental niche modelling software Maxent, 416 Lithops localities were examined against environmental variables of climate, dominant soil, geology, ecoregion and altitude. Predictions obtained suggested that a combination of suitable soil or geology and climatic conditions determine the limits of the range of distribution of the genus. Predictions for paleoclimatic conditions at the last glacial maximum suggested the area of distribution of the genus Lithops was significantly contracted at this time but that all current species had at least one locality suitable to sustain them. Predictions using future climate simulations suggest a significant reduction in the range of the genus and potential extinction of two species due to habitats becoming unsuitable. A prediction using suitability of different ecoregions supports the hypothesis for an origin of the genus near to the mouth of the Orange River.

Summary: In terms of number of taxa accepted at present – about 180 – Kalanchoe (Crassulaceae subfam. Kalanchooideae) is the third largest genus recognised in the family. Madagascar is home to more than one third of the recognised taxa with the rest spread across Africa, and the Near, Middle, and Far East. In terms of growth form (trees, various types of shrubs, herbs, epiphytes; all leaf succulents), Madagascar also harbours the greatest diversity found in the genus. Several Malagasy species of Kalanchoe have attracted significant research interest from horticultural, (eco-)physiological and invasions biological perspectives. However, the species that occur beyond Madagascar have not been studied to the same degree. This review provides a synthesis of field observations made over several decades, especially in southern Africa, and of available information on several aspects of kalanchoe biology and ecology assembled from a wide range of sources. Such synthesised knowledge is important for, inter alia, informing conservation management strategies for wild kalanchoe populations, as well as more widely for the grassland and savanna and, to a lesser degree, forest and thicket, habitats in which the species mostly occur.

Summary: Willem Frederik Reinier Suringar and Jan Valckenier Suringar between them named a large number of Melocactus species in the middle of the nineteenth and start of the twentieth century. All of them subsequently have been considered to be synonyms of M. macracanthos, M. stramineus, M. curvispinus subsp. koolwijkianus or M. ×bozsingianus. W. Suringar visited the West Indies, Suriname, Guyana and Trinidad, collecting plants. In Curaçao he took special note of melocacti. Through a study of their descriptions, herbarium material and published images, several new synonyms of their taxa are designated in this paper. One Suringar Melocactus, M. stramineus, recently demoted to a subspecies of macracanthos, is reinstated as a good species. An assessment of the work of the Suringars is made. It is noted that, in spite of reservations about their species concept, the Suringar taxa are valid and have to be considered in any taxonomic study of melocacti from the West Indies.
摘要：Willem Frederik Reinier Suringar和Jan Valckenier Surngar在19世纪中期和20世纪初命名了大量的甜瓜属植物。所有这些后来都被认为是M.macracanthos、M.stramineus、M.curvispinus subsp。koolwijkianus或M.×bozsingianus。W.Suringar访问了西印度群岛、苏里南、圭亚那和特立尼达，收集植物。在库拉索，他特别注意到了甜瓜。通过对它们的描述、植物标本和已发表的图像的研究，本文确定了它们分类群的几个新的同义词。最近被降级为macracanthos亚种的一种Suringar Melocatus，M.stramineus，被恢复为一个好物种。对Suringars的工作进行了评估。值得注意的是，尽管对其物种概念持保留意见，但Suringar分类群是有效的，必须在对西印度群岛甜瓜的任何分类学研究中予以考虑。

Summary: Ensuring the protection of the natural environment and its components from the damage caused by humans, whether directly or indirectly, is a commitment that can no longer be delayed or disregarded. However, before attempting to conserve wild populations of any kind of animal or plant, it is important to know which taxa are involved and where they live, as this also allows us to identify the relevant hotspots and suggest the areas which need to be protected. In this paper the author presents a provisional checklist of taxa belonging to the Crassulaceae family, selected as a priority for conservation. This list itemises taxa with a restricted distribution (endemic) in a specific area of the Euro-Mediterranean biogeographical context. Only the taxa with a range confined to a single country of this geographic area are dealt with in this paper. The study also focused on taxa whose distribution is included in the political boundaries of a single nation, in order to connect them with the local ‘Red List’ and appropriate legislative measures. We have selected ninety-seven taxa divided between species and subspecies (varieties and hybrids are excluded), with details on their distribution (country and biogeographic area), category of endemism, and conservation references.

Summary: Echinocereus fitchii subsp. albertii is a federally and state endangered cactus endemic to Texas that occurs exclusively on private lands. Sclerocactus brevihamatus subsp. tobuschii is a federally threatened and state endangered cactus occurring on private lands, as well as protected lands in Texas. Although listed under both federal and state laws, these laws give very limited protections to listed plants on private land. Nevertheless, section 7 of the Endangered Species Act requires federal agencies to ensure that their actions do not harm listed species. This paper provides case studies demonstrating how section 7 consultations lead to collaborations of federal and state conservation agencies, environmental consultants, non-profit organisations, and private landowners to conserve cactus populations in Texas, USA. Establishing good working relationships with landowners is essential for these conservation efforts.

Summary. Coleocephalocereus pluricostatus is an endemic cactus from eastern Brazil that occurs on naked gneiss/granite inselbergs in the Atlantic Forest biome. Here we report the extinction of a population of C. pluricostatus and the rapid decline of other populations of the species in eastern Minas Gerais, Brazil due to cochineal insects, diseases and mining operations. We offer some hypotheses to explain this dramatic decline and suggestions for monitoring the populations.

Summary: Echinocereus fitchii subsp. albertii (L.D.Benson) W.Blum & Mich.Lange, also known as Echinocereus reichenbachii var. albertii L.D.Benson, is a south Texas, USA endemic. The plant, commonly called black lace cactus, is listed as a federally endangered species in the United States. The objectives of this study are to 1 – survey populations of black lace cactus to determine current occurrence status, 2 – examine habitat and morphological features of black lace cactus across occurrences and 3 – examine the phylogeny of the E. reichenbachii-fitchii species complex to decipher the closest evolutionary relatives of black lace cactus. We photo-documented E. fitchii subsp. albertii individuals and confirmed extant populations in Kleberg, McMullen, and Refugio counties, Texas. Our study identified additional populations extending the sub-species' distributional range into Atascosa and La Salle counties, Texas. Flower colour of E. fitchii subsp. albertii is characteristic of the E. fitchii group. Central spines are absent to rare in E. fitchii subsp. albertii individuals in most populations, with only plants growing in the Kleberg Co. population commonly exhibiting central spines. We used genome skimming and assembly of nuclear ribosomal regions and nearly complete chloroplast genomes to examine phylogenetic relationships of fifteen taxa of Echinocereus. The most significant finding emerging from this phylogenetic study is that two distinct chloroplast genome lineages can be distinguished in E. fitchii subsp. albertii. One lineage includes individuals from Refugio Co. and McMullen Co. populations which are most closely related to E. reichenbachii subsp. caespitosus. The other lineage includes individuals from Atascosa and Kleberg Cos., which are most closely related to E. fitchii subsp. fitchii. These two lineages are not defined by geographic proximity.
