Sixty new or updated records of plants species are reported from the Sultanate of Oman, as a result of fieldwork and research undertaken. Five taxa represent new records for Arabia, twenty-seven taxa are new records for Oman, and twenty-eight records represent an extended distribution within Oman. Some previously doubtful records are confirmed. Brief comments are given on the phytogeography, taxonomy and ecology of the taxa. Most new records have been collected in mountainous areas, either in southern Oman or in northern Oman, mainly in areas that previously were botanically poorly known.

Epiphytes are an important component of the diversity of tropical forests, and they also have several ecological functions. Vegetation heterogeneity is one of the features responsible for the high biodiversity of the Atlantic Forest, especially in the domain’s seasonal semideciduous forest (SSF). This biodiversity presents as high endemism and species richness. Owing to the seasonal nature of SSF, organisms that require high humidity (e.g. epiphytes) would be expected to show low species richness in these forests. The aims of this study were to conduct a survey of the vascular epiphytes in remnants of montane SSF in the Serra do Ibitipoca, Brazil, and to evaluate the importance of habitat heterogeneity for the richness and composition of species in these areas. We also evaluated whether the intrinsic characteristics of the SSF phytophysiognomy and fragmentation could result in low species richness and a high number of accidental epiphyte species. The study was conducted in the course of 18 expeditions undertaken between September 2013 and December 2016, covering five fragments of montane SSF (totalling 23.6 ha). We recorded 96 species (only one of which is an accidental epiphyte), distributed across 41 genera and 10 families. This is the highest epiphytic species richness recorded in Brazilian SSF to date. The results refuted the initial hypothesis and reinforce the importance to the epiphytic community of conservation of fragments with different structures.
附生植物是热带森林多样性的重要组成部分，具有多种生态功能。植被异质性是大西洋森林，特别是季节性半落叶林生物多样性高的特征之一。这种生物多样性表现为高地方性和物种丰富度。由于SSF的季节性，需要高湿度的生物(如附生植物)在这些森林中可能显示出较低的物种丰富度。本研究旨在调查巴西伊比提波卡山(Serra do Ibitipoca)山地森林植被残余物中的维管附生植物，并评价生境异质性对该地区物种丰富度和组成的重要性。我们还评估了SSF植物地貌和破碎化的内在特征是否会导致低物种丰富度和高偶然附生物种数量。这项研究是在2013年9月至2016年12月期间进行的18次探险中进行的，覆盖了山地SSF的5个片段(总计23.6公顷)。共记录到96种附生植物，分布于10科41属。这是迄今为止巴西SSF记录的最高附生物种丰富度。研究结果驳斥了最初的假设，强调了不同结构片段保存对附生群落的重要性。

The focus of community ecology has shifted from the description of taxonomic composition towards an understanding of community assembly based on species’ ‘functional traits’. The functional trait approach is well developed for vascular plants, utilising variability of continuous phenotypic characters that affect ecological fitness, such as specific leaf area, tissue nitrogen concentration or seed mass, to explain community structure. In contrast, community assembly studies for poikilohydric cryptogamic plants and fungi, such as lichens, remain focused on broad categorical traits such as growth form difference: fruticose, foliose or crustose. This study examined intra- and interspecific variability for two highly promising continuous phenotypic measurements that affect lichen physiology and ecological fitness: water-holding capacity (WHC) and specific thallus mass (STM). Values for WHC and STM were compared within and among species, and within and among key macrolichen growth forms (fruticose and green-algal and cyanolichen foliose species), asking whether these widely used categories adequately differentiate the continuous variables (WHC and STM). We show large intra- and interspecific variability that does not map satisfactorily onto growth form categories, and on this basis provide recommendations and caveats in the future use of lichen functional traits.

Cerrado sensu stricto (a physiognomy of the Cerrado domain, the Brazilian savanna) is subject to the annual occurrence of fire. Data on the epiphytic community in this physiognomy is scarce, as is evaluation of the influence of fire on its structure and composition. The aim of this study was to describe the structure of the vascular epiphyte community and its relationships with phorophytes in the Cerrado domain, Southeast Region of Brazil, after the passage of fire. We found the greatest abundance of epiphytes in the upper strata (65% of the individuals occurring above 3 m in height) and the dominance of three generalist species (Tillandsia streptocarpa, T. recurvata and Epiphyllum phyllanthus), suggesting that fire has an influence on the structure and composition of the epiphytic community.

A striking new species of Begonia, B. joshii, is described from Amazonas Region, Peru. The new species is unusual among the South American members of the genus both in its combination of tuberous habit with peltate leaves and in living in a seasonally dry tropical forest environment. A phylogeny of this and closely related species is presented, and its sectional affiliation and IUCN conservation status are discussed. A key to the peltate Peruvian species of Begonia is provided.
