Floral diversification in Loranthaceae reaches its highest peak in the Andes. The flowers of the exclusively Andean genus Tristerix exhibit tubular and vividly coloured flowers pollinated by hummingbirds. We studied inflorescence and flower morphoanatomy of the two Colombian species, T. longebracteatus and the highly endangered T. secundus . Both species have terminal racemes with up to 26 ebracteolate flowers, of which the proximal one opens and sets fruits first. The slightly irregular calyx initiation is followed by the simultaneous initiation of petals and the successive initiation of stamens. Anthesis is fenestrate, explosive, and triggered by the tension of the style against the abaxial petals, a mode so far not reported in Loranthaceae . Anthetic petals spread symmetrically in T. longebracteatus and asymmetrically in T. secundus . Nectar is produced by a supraovarial disk and by the petal mesophyll. Floral lifespan lasts up to 20 days. The hummingbirds Eriocnemis vestita and Pterophanes cyanopterus are the likely pollinators of T. secundus . Morphological traits are inconclusive to support one of the two competing sister group relationships that involve Tristerix , as the lack of cataphylls in renewal shoots links Ligaria and Tristerix , whereas the terminal inflorescences support its relationship with Desmaria and Tupeia .

The original description of Helianthemum mathezii regarded the species to be a therophyte. However, the detailed observation of the holotype of H. mathezii , as well as newly collected specimens from the type locality, does not support its condition of annual plant. Further study has led to the conclusion that all these plants can readily be identified as H. pomeridianum ; the descriptions of H. mathezii and H. pomeridianum are equivalent except for the habit, being the former annual and the latter suffruticose. We show in this study that H. mathezii is to be considered a synonym of H. pomeridianum , and report a new locality of H. pomeridianum in Morocco. Also, we provide the first chromosome count for this species (2n = 22) which emphasizes the close relationship of H. pomeridianum to H. subgen. Plectolobum .

DNA barcoding in combination with morpho-anatomical analysis was applied to study the diversity of crustose coralline algae associated to two maerl beds from two protected Atlantic European areas from Brittany and Galicia —France and Spain, respectively—. Given the records of gametophytes of the maerl species Phymatolithon calcareum under crustose growth-forms, and that associated crustose coralline algae appear to be involved in the recruitment of new maerl plants, we compared the species composition between the associated crustose coralline algae to Breton and Galician maerl beds with the maerl species identified in these beds in previous DNA barcoding surveys. Our molecular results revealed higher species diversity in associated crustose coralline algae than in maerl-forming species. Nine taxa of crustose coralline algae were found in both study areas: four in Brittany and five in Galicia. Three species from Brittany were identified as Phymatolithon calcareum, Phymatolithon lamii , and Lithophyllum hibernicum . The remaining six ones were assigned to the genera Phymatolithon and Mesophyllum , along with Lithothamnion and Lithophyllum . Morpho-anatomical examination of diagnostic characters corroborated our molecular identification. Our results showed that the most representative genus of crustose coralline algae in Brittany was Phymatolithon , while in Galicia was Mesophyllum . In Brittany, Phymatolithon calcareum was found under both growth-forms, maerl and crustose coralline algae, the latter assigned to the gametophyte stage by the presence of uniporate conceptacles. The recruitment of new maerl plants involving associated crustose coralline algae with maerl beds may occur, but only we can affirm it for Phymatolithon calcareum in Brittany. By contrast, the different species composition between both growth-forms in the Galician maerl beds would indicate that the fragmentation of own free-living maerl species appears to be the most common propagation mechanism.

The aim of this study was to describe morphological variations of Opuntia jaliscana in 5 wild populations in the state of Jalisco (Mexico). Populations were selected along an environmental aridity gradient, and 61 vegetative and reproductive characters from 25 individuals were measured per population. Quantitative characters were analyzed independently by a one-way ANOVA test using the site as variation factor. Subsequently, a discriminant analysis was performed. The discriminant analysis results showed that the 46% of the total variation was explained by the first four discriminant functions. The analysis of overall membership between populations indicated that individuals were correctly classified in 87% of cases. Pearson linear correlation between the most significant variables and the aridity index, showed a positive relationship to cladode thickness and diameter of the trunk. The population from Tierra Blanca shows an outlier behavior because of variation in cladode thickness and fruit size, which might be related to plasticity of individuals to have a greater availability of water, while in Los Vallejo the separation might be due to selection by management and use. The remaining populations exhibited some morphological variability without separation.

Carex sylvatica subsp. paui is a poorly studied taxon considered endemic from a few places in the western Mediterranean. It has been frequently misidentified as C. sylvatica subsp. sylvatica . To date, it has been reported only from the NE Iberian Peninsula and the NW Africa. We use molecular —nuclear ribosomal and plastid sequences— and morphological data to shed light on the taxonomic circumscription and distribution of this taxon, especially regarding its distinction from the type subspecies. The genetic data support the recognition of C. sylvatica subsp. paui as an independent taxon, and confirm new records from the Balearic and Tuscan archipelagos. It implies a considerable increase in its range and a new taxon for the Italian flora. Strikingly, the morphometric analyses revealed that the Sicilian type specimen of C. laxula identifies this species with C. sylvatica subsp. paui . We consider that the taxon should be ranked at the species level. Based on the priority of the name C. laxula over C. paui , we subsume C. sylvatica subsp. paui in C. laxula . We also provide notes on the ecology of the species.

Freshwater systems are particularly susceptible to non-native organisms, owing to their high sensitivity to the impacts that are caused by these organisms. Species distribution models, which are based on both environmental and socio-economic variables, facilitate the identification of the most vulnerable areas for the spread of non-native species. We used MaxEnt to predict the potential distribution of 20 non-native aquatic macrophytes in the Iberian Peninsula. Some selected variables, such as the temperature seasonality and the precipitation in the driest quarter, highlight the importance of the climate on their distribution. Notably, the human influence in the territory appears as a key variable in the distribution of studied species. The model discriminated between favorable and unfavorable areas with high accuracy. We used the model to build an invasion risk map of aquatic macrophytes for the Iberian Peninsula that included results from 20 individual models. It showed that the most vulnerable areas are located near to the sea, the major rivers basins, and the high population density areas. These facts suggest the importance of the human impact on the colonization and distribution of non-native aquatic macrophytes in the Iberian Peninsula, and more precisely agricultural development during the Green Revolution at the end of the 70’s. Our work also emphasizes the utility of species distribution models for the prevention and management of biological invasions.

Sternbergia is a genus containing mostly remarkable autum flowering taxa within Amaryllidaceae. Its distribution ranges from the Mediterranean region through the Irano-Anatolian region to Caucasus and Central Asia. In Flora of Iraq, the information about the occurrence, habitat, and distribution of its species is outdated or incomplete. The main aim of this study has been to contribute with new data from the field in order to update its status in the Kurdistan Region. Botanical field surveys were mostly carried out between 2013 and 2015 in autumn and spring. The main result of this study has been the occurrence of 3 species of Sternbergia: S. colchiciflora, which is reported in this study for the first time for the Kurdistan Region and therefore for Iraq; S. clusiana, which has been rediscovered in Iraq; and S. vernalis, which has been found again in the Berwarya Mountains, after being considered a lost species in Iraq over the last 80 years. These 3 observed species occur in the mountains of Amadiya District, making this area the richest territory for Sternbergia in the country. Due to certain factors that currently threaten their natural habitats, they are rare species and could be regarded as potentially endangered at regional level according to the IUCN criteria.
紫檀属是紫檀科中一个主要包含秋季开花分类群的属。其分布范围从地中海地区到伊朗-安纳托利亚地区到高加索和中亚。在《伊拉克植物志》中，关于其物种的发生、栖息地和分布的信息已经过时或不完整。这项研究的主要目的是提供来自实地的新数据，以便更新其在库尔德斯坦地区的状况。植物野外调查主要在2013 - 2015年秋季和春季进行。本研究的主要结果是发现了3种Sternbergia: S. colchiciflora，这是本研究在库尔德斯坦地区和伊拉克首次报道的;在伊拉克重新发现的美国克卢西亚纳;以及在过去80年里被认为是伊拉克消失的物种，如今在伯瓦亚山脉再次被发现的春天花。这3种观察到的物种出现在Amadiya区的山区，使该地区成为该国Sternbergia最丰富的地区。由于某些因素目前威胁到它们的自然栖息地，它们是稀有物种，根据世界自然保护联盟的标准，它们可以在区域一级被视为潜在濒危物种。

The genus Mulinum is endemic to southern South America and is ecologically important because of its dominance in the vegetation of the high Andes and the Patagonian steppe. We present a treatment in which 10 species and 3 new varieties are accepted. A diagnostic key to the species is included, and lists of synonyms, morphological descriptions, observations on the morphological affinities between species, review of the relevant literature, illustrations, and distribution maps are provided. We also analyze and resolve nomenclatural problems, and we provide a list of dubious names and excluded names. Six new synonyms are recognized, including the names M. axilliflorum and M. echinus. Mulinum famatinense is considered here a variety of M. triacanthum . The other two varieties recognized are M. spinosum var. hirsutum and M. spinosum var. zechii . The area of distribution for M. crassifolium, M. leptacanthum, M. spinosum, M. triacanthum, and M. ulicinum has been extended. In addition, 27 lectotypes and one neotype are designated.
