The Sierra de Maigualida is a poorly explored mountain range in the central Guayana Shield with high levels of endemism. In the present installment, this area is further delimited and mapped, toponymy is reviewed, and the genus Ilex L. is locally reviewed, with two species, namely I. huberi J.R.Grande sp. nov. and I. maigualidensis J.R.Grande sp. nov., described as new to science. Ilex huberi sp. nov. can be distinguished by its leaf blades strongly revolute, mucronate, and with obscure secondary venation, simple dichasia, and depressed-lunate sepals; I. maigualidensis sp. nov. by its dull leaves, flowers with undeveloped styles, and capitate-subcoronate stigmata. Stem buds and cataphylls are proposed as useful characters in species delimitation within the genus, while I. magnifructa Edwin is illustrated for the first time. A key is presented to differentiate all the species of Ilex of the Sierra de Maigualida.

As a part of a taxonomic update of the family Convolvulaceae Juss. for Guayana Shield, the species Jacquemontia austiniana J.R.Grande sp. nov., is described and illustrated as new to science. This species is characterized by its linear-subulate bract, ovate-lanceolate external sepals, conspicuously acuminate, villose, with the margins ciliate, and a relatively large and infundibuliform corolla. To date, this is the only species of Jacquemontia Choisy endemic to the Guayana Shield; its relationships within the genus are still to be elucidated.

Material of Jania J.V.Lamour. with a different morphology from the typical one attributed to J. longifurca Zanardini and J. rubens (L.) J.V.Lamour.—the only species in this habitat in Galicia—has been detected in the maerl beds of Galicia. This morphology consists on: thin intergenicula, an irregular pattern of dichotomies and secondary attachment discs that facilitate the refixation to the substrate, all of them similar to those of other southern species of Jania. Nevertheless, the integrative taxonomic study of this material and other collections from rocky habitat confirmed its identification as J. longifurca. Thereby, the atypical morphology with thin intergenicula and secondary attachment disc is dominant in samples of J. longifurca from maerl beds, while the samples from rocky environments showed the typical robust intergenicula. Moreover, molecular analysis resolved some phylogenetic affinities with samples from New Zealand, where this species is not recorded. It is concluded therefore the morphological variation related to the environment and it is evident the need of molecular studies to clarify this genus taxonomy, which is based fundamentally on morphological characters.

The composition, abundance, and distribution of epiphytic macroalgae living in meadows of Zostera marina L. in the northwestern Iberian Peninsula are here analyzed. We identified 63 species: 40 red algae, 16 brown algae, and 7 green algae. Most of them are classified as filamentous or filiform functional forms, while Pneophyllum fragile Kütz. was the only encrusting species. In general, the surface covered by epiphytes on the leaves of Zostera marina was low and a 43% of species were only found in juvenile stages. Regarding their frequency, 10 species were collected in the majority of the areas, while others were rare. Most species were found both epiphytic and in other substrata of the meadows, but 9 were exclusively epiphytic. We detected 9 introduced species.

We here present the partial results of a research project focusing on the lichen diversity and lichen-induced biodeterioration processes in two archaeological places -Siega Verde, Spain, and Foz-Côa, Portugal, both declared World Heritage sites by the UNESCO-. In this article the floristic results corresponding to the area of Siega Verde -Salamanca- are presented. In total, 97 taxa of lichens and two lichenicolous fungi have been identified. The presence of Peltula lobata J.Marques & al., Cyphelium lecideinum (Nyl.) Trevis., Variospora cancarixiticola (Nav.-Ros. & al.) Arup & al., and the lichenicolous fungus Llimoniella phaeophysciae Diederich & al. is particularly relevant. Somedifferences have been observed between the floristic composition of this area and that of the neighbor of Foz-Côa, attributable to the eutrophicationof Siega Verde.

The goal of this study was the identification of mycorrhizal fungi associated with three terrestrial orchids of the genus Bletia Ruiz & Pav.: B. roezlii Rchb. f., B. purpurata A.Rich., and B. punctata Lex., in Barranca del Cupatitzio Natural Reserve - Michoacán, México - . Thirty-nine strains were isolated and morphologically characterized. Nine strains were selected from the molecular analysis. Bletia punctata, an endemic species of Mexico, showed the lowest variability in mycorrhizal fungi. Morphological analysis showed that 39 isolated strains belong to the ‘Rhizoctonia-like fungal complex’. According with the tree of Euclidian distances generated by the analysis WARD, all isolates were included into four subgroups, all related to the genus Tulasnella J.Schröt - which belongs to the ‘Rhizoctonia-like fungal complex’?. Molecular and phylogenetic analysis of the nine selected strains corroborated the results of the morphological study: the sequences obtained were clustered in four subclades related to species of Tulasnella. Our results indicate that a single species of Bletia from a single locality can be associated with different species of mycorrhizal fungi, at least during the adult stage and that the combination of morphological and molecular analyses is a good tool to identify orchid mycorrhizal fungi.
本研究的目的是鉴定与三种陆生兰科植物Bletia Ruiz & Pav的菌根真菌。: B.罗兹利。B.紫癜;和B. punctata Lex。，在Barranca del cupatizio自然保护区- Michoacán, m xico。分离得到39株菌株并进行了形态鉴定。从分子分析中筛选出9株菌株。斑点布利亚(Bletia punctata)是墨西哥特有种，其菌根真菌的变异性最低。形态学分析表明，39株分离菌株属于“根丝胞菌样真菌复合体”。根据WARD分析生成的Euclidian距离树，所有分离株被分为4个亚群，均与Tulasnella J.Schröt属有关，属于“Rhizoctonia-like fungi complex”?对所选菌株的分子和系统发育分析证实了形态学研究的结果:所获得的序列聚集在图拉菌属的4个亚枝上。本研究结果表明，至少在成虫阶段，来自同一地区的一种蓝属植物可能与不同种类的菌根真菌有关联，形态和分子分析相结合是鉴定兰花菌根真菌的良好工具。

Euphorbia duvalii Lecoq & Lamotte is an endemic species from the Catalan-Occitan territory -western Mediterranean area- and is usually found in the south of France. Euphorbia duvalii has been cited from some localities of the Iberian Peninsula, but in later reviews all of these citations were finally identified as other species of Euphorbia L. One of these citations, from the Alt Empordà -Girona, Spain-, was of specific interest because not all the sources agreed on what the species was. To clarify whether or not this species is really present in the Iberian Peninsula, we examined new material from this population in order to establish whether the species is in fact E. duvalii. Once the morphology of the specimens from the Serra de Bac Grillera population had been analysed, we were able to confirm that they were indeed E. duvalii. This means that this is the only area on the Iberian Peninsula where this endemic species has been identified. The population is located in a rocky meadow that contains some scrub and is surrounded by pinewoods. Because this is the one and only Iberian population, a management and conservation plan needs to be drawn up to ensure its preservation.
Euphorbia duvalii Lecoq & Lamotte是加泰罗尼亚-奥西坦地区(地中海西部地区)的特有物种，通常在法国南部发现。Euphorbia duvalii在伊比利亚半岛的一些地方被引用，但在后来的评论中，所有这些引用最终都被确定为Euphorbia L.的其他物种。其中一篇来自西班牙的阿尔恩波顿-赫罗纳的引用引起了特别的兴趣，因为并不是所有的来源都同意该物种是什么。为了弄清这个物种是否真的存在于伊比利亚半岛，我们检查了来自这个种群的新材料，以确定这个物种是否真的是E. duvalii。一旦分析了Serra de Bac Grillera种群标本的形态，我们就能够确认它们确实是E. duvalii。这意味着这是伊比利亚半岛上唯一发现这种特有物种的地区。种群位于岩石草地上，有一些灌木，周围是松林。由于这是唯一的伊比利亚种群，因此需要制定管理和保护计划以确保其得到保护。

To explore if fruit morphology could aid in taxonomy of the genus Pimpinella L., we have undertaken a study of fruits from 26 Turkish taxa of Pimpinella using light and scanning electron microscopy—SEM—. A great deal of inter and intraspecific variation for both fruit shape and surface was observed. Fruit shapes of Turkish taxa of Pimpinella range from oblong-cylindrical to subglobose and indumentum when present can be strigose, hispid and may include hamate trichomes. Variation in fruit surface is also considerable and allows recognizing nine different ornamentation patterns. However, variation in shape, surface ornamentation and indumentum is not tightly associated since species with similar fruit shapes do not necessarily have similar surface ornamentation. To jointly analyse fruit morphology together with the most commonly used morphological characters of the whole plant and to compare morphological evidence with available phylogenetic hypotheses, a cluster analysis was also performed: the Turkish species of Pimpinella were clustered into two distinct groups, the second one subdivided in another two subgroups.
