The objective of this study is two-fold: firstly, to review the local endemic plants of Tunisia and northern Morocco (Mediterranean coast and Rif region) and the extent to which extinction risk status characterisations have been assigned to date to the endemic plants of these areas; and secondly, to identify which of these unique taxa are conserved ex-situ around the world. For the first aim, five major online databases as well as widely scattered literature sources were consulted; for the latter, the PlantSearch facility of Botanic Gardens Conservation International was used, followed by communication with domestic institutions. The examination of the extent of the ex-situ conservation of endemic plants of the Mediterranean part of northern Morocco (n=94 taxa) showed that only six of them are conserved in one conservatory, four arboretums and 18 botanic gardens of 10 countries, totalling only 25 accessions, with 40% of these in UK institutions. The threatened and near threatened flora of northern Morocco (Mediterranean coast and Rif region) is estimated at 64 taxa; only five of these are preserved ex-situ, among which only Abies marocana and Rhodanthemum hosmariense are assessed as effectively conserved. For the endemic flora of Tunisia which is estimated at 83 taxa, we have found only one taxon (Calendula suffruticosa subsp. suffruticosa) conserved ex-situ. With scarce evaluations made to date, the threatened endemic flora of Tunisia is limited to one taxon only (Rumex tunetanus). This study presents comprehensive and evaluated lists of the endemic plant taxa found in the studied countries/regions, indicating that consensus is compromised among the widely used taxonomic/phytogeographical online sources. Additionally, it is suggested that more coordinated efforts are needed to conserve the plant heritage of these countries, through integrated management, species-prioritisation, restoration of populations of threatened taxa, inclusion of threatened species in national lists of protected species, and establishment of seed banks focused on the wild flora.

这项研究的目的有两个方面：首先，回顾突尼斯和摩洛哥北部（地中海沿岸和里夫地区）的地方特有植物，以及迄今对这些特有植物的灭绝风险状况表征的程度区域 其次，确定哪些独特的分类单元在世界各地被异地保存。为了第一个目标，参考了五个主要的在线数据库以及分布广泛的文献资源。对于后者，使用了国际植物园保护组织的PlantSearch设施，然后与国内机构进行了沟通。对摩洛哥北部地中海地区（n = 94类群）特有植物的迁地保护程度的检查表明，其中只有6个在一个温室中得到保存，10个国家/地区的4个植物园和18个植物园，总共只有25种材料，其中40％在英国的机构中。摩洛哥北部（地中海沿岸和里夫地区）受威胁和近受威胁的植物群估计有64个分类单元。其中只有五个被异地保存，其中只有Abies marocana和Rhodanthemum hosmariense被评估为有效保存。对于估计为83个分类单元的突尼斯地方性植物区系，我们发现仅一个分类单元（金盏草suffruticosa亚种suffruticosa）在异位保存。迄今为止缺乏评估，突尼斯受威胁的地方病区系仅限于一个分类群（Rumex tunetanus）。这项研究提供了在所研究的国家/地区中发现的特有植物类群的综合和评估列表，表明在广泛使用的生物分类/植物地理在线资源中，共识已受到损害。此外，建议通过综合管理，物种优先化，恢复受威胁生物群的种群，将受威胁物种列入国家保护物种清单和建立种子，需要采取更多协调措施来保护这些国家的植物遗产。银行专注于野生植物。
