Elwendia wolfii and E. caroides are two herbaceous perennials that were initially classified in the Bunium genus and later transferred to the Elwendia genus. They are a rich source of bioactive and antioxidant compounds and have the potential to become sources of oil-bearing crops. The aim of this study was to investigate requirements for embryo growth, dormancy break and seed germination in these two species. The effects of gibberellic acid (GA3) and dry storage were also examined to determine the type of dormancy. The pericarps and seed coats of both species were water-permeable, and the embryos were small and differentiated but underdeveloped, with initial embryo lengths of 0.28 mm in E. wolfii and 0.96 mm in E. caroides, respectively. These underdeveloped embryos were either di (>98%) or tricotyledonous (<2%) and required cold temperatures to grow, indicating that these seeds had morphological dormancy (MD). The critical length required for germination was 3.44 mm for E. wolfii and 4.17 mm for E. caroides. However, seeds of both species reached less than 50% final germination if subjected only to cold incubation. Higher final germination was possible if seeds were pre-treated with dry cold storage (-22 ºC) or exposed to GA3, indicating the existence of physiological dormancy (PD) in part of the seed population. Therefore, both species had non-deep complex morphophysiological dormancy (MPD). This study demonstrates that E. caroides and E. wolfii share the same germination requirements, suggesting a common ecological strategy in their seed germination process.

The melliferous flora of Central Western Morocco, precisely in the territory of the Ait Baâmrane of Sidi Ifni Province was studied between 2016 and 2018 using surveys among beekeepers and by observing the behavior of bees towards flowers. The plants foraged by bees were collected, identified and listed. A total of 117 honey species were recorded, representing 41.64% of the 281 species of the total flora of the study area, belonging to 98 genera and 40 families. The Asteraceae family is the most represented with 17.95%, followed by Labiatae and Leguminosae with 6.84% each. The area is characterized by a high rate of endemism, estimated at 26.5% of the 117 melliferous species. However, there are species classified as rare and endangered taxa, estimated at 10 species. According to their biological types, Therophytes represent 36.75% of the foraged species, followed by Chamephytes (17.95%). Regarding the flowering period, it lasts throughout the year. Spring however is the most represented period with 42.45% of the plants, followed by summer with 28.98%, then winter and autumn, with 15.10% and 13.47% respectively. Melliferous plants with yellow flowers are the most attracted by bees (28.21%), followed by white flowers (24.79%). These listed plants are either foraged for their nectar and pollen (74.36%), only pollen (15.38%), or only nectar (8.55%). In addition, they have other uses, such as edible, medicinal, and others. It appears from this study that the conservation of the melliferous flora is very imperative in order to improve and promote the continuity of the beekeeping sector in the region.

Helianthemum polygonoides is a perennial halophyte identified in 1987 in the Saltmarsh of Cordovilla (Albacete, SE Spain). In 2004 its distribution area was approximately 16 hectares, and its population was estimated at around 185000 adult individuals. Thus, this species is considered a local endemism due to its restricted distribution area, being catalogued as a "Critically Endangered" (CR). The main goal of this study is to review the current situation of the endemism, updating its distribution area and current threats and, consequently, establishing up-to-date conservation guidelines. A marked increment in the H. polygonoides population have been found (381909 individuals were estimated in 2022 census). We located new populations of H. polygonides, increasing its core distribution area and revealing the consolidation of proposed protection measures. In this context, our results have confirmed the direct relationship between the population size and the protection measures. According to the threat’s assessment, we have observed that most of the threats and impacts have been reduced (e.g., grazing) or stopped (e.g., accumulation of debris). However, we have found new threats (e.g., rabbit proliferation, wild boar damages, and fires), emphasising the need to review and update the Recovery Plan of H. polygonoides. In fact, we want to be pointed out that the mentioned threats are in constant change. We suggest the inclusion of new guidelines to control the new-found threats and provide eight new conservation guidelines to improve the conservation status of the current populations of H. polygonoides.
Helianthemum polygonoides 是一种多年生盐生植物，1987 年在科尔多瓦盐沼（西班牙东南部阿尔瓦塞特）被发现。2004 年，其分布面积约为 16 公顷，成年个体数量约为 185000 个。因此，由于其分布区域有限，该物种被视为当地特有物种，并被列为 "极度濒危"（CR）物种。本研究的主要目的是回顾这一地方特有物种的现状，更新其分布区域和当前面临的威胁，从而制定最新的保护准则。我们发现 H. polygonoides 的种群数量显著增加（2022 年普查估计为 381909 个）。我们找到了 H. polygonoides 的新种群，扩大了其核心分布区，并揭示了拟议保护措施的巩固性。在这种情况下，我们的结果证实了种群数量与保护措施之间的直接关系。根据威胁评估，我们发现大多数威胁和影响已经减少（如放牧）或停止（如瓦砾堆积）。然而，我们也发现了新的威胁（如野兔扩散、野猪破坏和火灾），这就强调了审查和更新 H. polygonoides 恢复计划的必要性。事实上，我们希望指出，上述威胁是不断变化的。我们建议纳入新的指导方针，以控制新发现的威胁，并提供八项新的保护指导方针，以改善目前 H. polygonoides 种群的保护状况。

Carex hartmaniorum (sect. Racemosae, Cyperaceae) is reported for the first time for Spain, from a single known population in the Cerdanya region (Eastern Pyrenees, Girona province). The main differences with closely related taxa are highlighted, a dichotomous key to differentiate this species from members of section Racemosae inhabiting the Iberian Peninsula and the Pyrenees is presented, and some comments on its distribution and ecology are made. A preliminary conservation assessment for Spain resulted in the proposal of the Endangered category of C. hartmaniorum for Spain.

Cistus pouzolzii is a species distributed in the western Mediterranean. Its populations are located in France and North Africa, being absent in the Iberian Peninsula.. It was described by Delile, but its taxonomic and nomenclatural status has been discussed by several authors, mainly based on its particular combination of morphological characters. We have recently found several populations of a Cistus species whose morphological characters match those of C. pouzolzii. To confirm the taxonomic identity of these populations, a comparative study was performed using herbarium specimens of C. pouzolzii from France and North Africa. In addition, two chloroplast regions were sequenced to study the phylogenetic relationships between the newly discovered Iberian populations and the rest of the species of the genus Cistus, including the sequences belonging to C. pouzolzii from France and Morocco previously used. Both analyses (morphological and phylogenetic studies) confirmed that the specimens sampled in the Iberian populations were C. pouzolzii. Furthermore, both the nomenclature of this species and its conservation status are briefly discussed.
Cistus pouzolzii 是一种分布于地中海西部的植物。其种群分布在法国和北非，伊比利亚半岛没有分布。它由 Delile 描述，但其分类学和命名学地位已被多位学者讨论过，主要是基于其形态特征的特殊组合。我们最近发现了几个形态特征与 C. pouzolzii 相同的肉苁蓉种群。为了确认这些种群的分类学特征，我们利用标本馆中来自法国和北非的 C. pouzolzii 标本进行了比较研究。此外，还对两个叶绿体区域进行了测序，以研究新发现的伊比利亚种群与肉苁蓉属其他物种之间的系统发育关系，包括之前使用的属于法国和摩洛哥 C. pouzolzii 的序列。这两项分析（形态学和系统发育研究）都证实了伊比利亚种群中的样本为 C. pouzolzii。此外，还简要讨论了该物种的命名及其保护状况。

Orobanche salviae is a European orophyte and considered an exclusive parasite of Salvia glutinosa. Here we provide the first report of the species for the Iberian Peninsula, which we discovered recently in the eastern Catalan Pyrenees. The closest reliable known localities are in the French Maritime Alps, although it was also previously reported with uncertainty from the French Pyrenees. The new found populations are located at the absolute western limit of the distribution of the species. We provide a description of its distribution, habitat and, given its rarity, we suggest a category of threat following the IUCN criteria.

Allium sect. Codonoprasum represents an evolutionarily young and rapidly radiating group of bulbous geophytes, with a significant proportion of polyploids and minor morphological differences between species. In the last 20 years, dozens of new species of this section have been described from the Mediterranean. Still, very little new information has been obtained on most of them since their description, especially concerning cytogenetic, molecular, and distribution data. Allium goumenissanum is a recently described species of this section, known only from three nearby localities in northern Greece. During the last 10 years, the senior authors' team collected population samples of an unknown species of this section from the southern Balkans, which appeared to be representative of A. goumenissanum. Using an integrated approach employing a range of methods (cytogenic, molecular, morpho- and micromorphological methods), the populations of an unknown species were compared with morphologically similar species A. goumenissanum and A. stamatiadae. AFLP, ITS sequencing and genome size analyses revealed that all the populations of the unknown species represent A. goumenissanum, and that this species is differentiated genetically and in genome size from A. stamatiadae. ITS sequencing indicates an allotriploid origin of A. goumenissanum from unknown ancestors. The characterization of the morphology and reproduction of A. goumenissanum is completed and micromorphological and anatomical characteristics of the leaves of both species are newly published. The distribution of A. goumenissanum, based on new data, now includes a more extensive area of north central Greece and the species has been found as a new one for Bulgaria.
薤白科Codonoprasum 代表了一个进化年轻、辐射迅速的球根地生植物群落，多倍体占很大比例，物种之间的形态差异很小。在过去的 20 年中，地中海地区描述了数十个该科的新物种。不过，自描述以来，关于其中大多数物种的新信息，特别是细胞遗传学、分子和分布数据，仍然很少。Allium goumenissanum 是新近描述的该区系的一个物种，仅从希腊北部附近的三个地方知道它的存在。在过去 10 年中，资深作者的团队从巴尔干半岛南部采集了该部分一个未知物种的种群样本，该样本似乎是 A. goumenissanum 的代表。采用综合方法（细胞学、分子学、形态学和微形态学方法），将未知物种的种群与形态上相似的物种 A. goumenissanum 和 A. stamatiadae 进行了比较。AFLP、ITS 测序和基因组大小分析表明，该未知物种的所有种群均代表 A. goumenissanum，而且该物种在基因组和基因组大小上与 A. stamatiadae 有所区别。ITS 测序表明，A. goumenissanum 起源于未知祖先的异源三倍体。goumenissanum 的形态和繁殖特征的研究已经完成，并新发表了这两个物种叶片的微观形态和解剖特征。根据新的数据，A. goumenissanum 的分布现在包括了希腊中北部更广阔的地区，该物种也被发现为保加利亚的新物种。
