The breeding system and pollination ecology of Tamarix taklamakanensis, an endangered shrub occurring in sand dunes in the Taklamakan Desert, were examined by seven pollination treatments and observational studies in natural populations in 2019.The results showed that T. taklamakanensis exhibits an outcrossed breeding system that is dominated by insect‐pollination. It is largely self‐incompatible, with infrequent occurrence of anemophily, but relies strictly on pollinators in outcrossing. The pollen vitality could last about six days versus the stigma receptivity last about one day. Two effective pollinators were detected, and the peaks of visitation were 10:30–13:30, 16:30–17:30 and 18:30–19:30 h. Seed set by artificial cross‐pollination was significantly higher than natural pollination rates, and seed set for a population with high insect visitation rates was significantly higher than a population with low visitation rate, suggesting that pollen limitation is an important constraint on seed production for this species. Adverse weather conditions and habitat fragmentation were speculated to be the primary factors affecting the insect visitation of T. taklamakanensis in the Taklimakan Desert.

Two new species of Bulbophyllum,B. barcelonae and B. pelseri are described here from the Pantabangan-Carranglan Watershed Forest Reserve, Luzon Island, Philippines. Bulbophyllum barcelonae resembles B. charisae, but differs by having smaller vegetative parts, ovate petals with a rounded apex, and a labellum with two ridges that are strongly angled outwards the adaxial surface, rounded proximal crests, and a canaliculate abaxial surface. Bulbophyllum pelseri resembles B. aureobrunneum but differs by having caducous sheath covering the pseudobulbs, punctulate leaf surface, shorter leaves, absence of transverse callus in median portion of labellum, median portion with short, rounded ridge, rounded apex, and triangular stelidia. These discoveries increase to 207, the known species of Bulbophyllum in the Philippines.

Norway launched a national action plan on wetland restoration in 2016. So far, 90% of the restoration effort has been on peatland restoration, with about 140 mires restored so far. There are three main restoration goals stated in the action plan: 1) limit greenhouse gas (GHG) emission, 2) climate adaptation and 3) improved ecological condition. Quantifying the outcome of the restoration actions is necessary to evaluate whether the goals of the action plan are met. A vegetation monitoring protocol was suggested before restoration started and has been implemented at five restoration sites. As the peatland restoration effort in Norway is increasing, it is timely to evaluate if the data currently collected can measure peatland restoration outcome. We evaluate the monitoring protocol based on statistical analyses of the data collected at two sites, describe how indicator species can be identified using generalized composition data used as the basis for classifying habitats in Norway (EcoSyst framework), and suggest the way forward for peatland restoration monitoring in Norway. Data collected according to the monitoring protocol can document changes in species composition at restoration sites, but has limitations when the ecological complexity at the sites increases and reference sites are unavailable. We argue that adjusting the monitoring protocol will: 1) facilitate alignment with existing peatland research; 2) connect better with monitoring programs where data is collected applying EcoSyst framework principles; and 3) enable upscaling to cover the wide variation emerging in peatland restoration.

A new salsify species, Tragopogon davutii-turanii, is described from Anatolia based on micro-/macro-morphological and molecular evidence. The new species is morphologically similar to T. vvedenskyi and T. abbreviatus, but differs from T. vvedenskyi mainly in ligule colour and from T. abbreviatus by achene characters and number of phyllaries. In contrast to morphological similarities, based on the phylogenetic tree obtained from nrDNA ITS sequences T.davutii-turanii is closely related to T. stenophyllus and T. coelesyriacus. Diagnostic characters, description, and conservation status of the new species, as well as micro- and macro-morphological features of its achenes and pollen grains, are provided.

Litter decomposition represents a major path for atmospheric carbon influx into Arctic soils, thereby controlling below-ground carbon accumulation. Yet, little is known about how tundra litter decomposition varies with microenvironmental conditions, hindering accurate projections of tundra soil carbon dynamics with future climate change. Over 14 months, we measured landscape-scale decomposition of two contrasting standard litter types (Green tea and Rooibos tea) in 90 plots covering gradients of micro-climate and -topography, vegetation cover and traits, and soil characteristics in Western Greenland. We used the tea bag index (TBI) protocol to estimate relative variation in litter mass loss, decomposition rate (k) and stabilisation factor (S) across space, and structural equation modelling (SEM) to identify relationships among environmental factors and decomposition. Contrasting our expectations, microenvironmental factors explained little of the observed variation in both litter mass loss, as well as k and S, suggesting that the variables included in our study were not the major controls of decomposer activity in the soil across the studied tundra landscape. We use these unexpected findings of our study combined with findings from the current literature to discuss future avenues for improving our understanding of the drivers of tundra decomposition and, ultimately, carbon cycling across the warming Arctic.
枯落物分解是大气碳流入北极土壤的主要途径，从而控制地下碳的积累。然而，人们对苔原垃圾分解如何随微环境条件变化知之甚少，这阻碍了对未来气候变化下苔原土壤碳动态的准确预测。在 14 个月的时间里，我们在格陵兰西部的 90 个地块中测量了两种对比鲜明的标准枯落物（绿茶和路易波士茶）的景观尺度分解情况，这些地块涵盖了小气候和地形、植被覆盖和特征以及土壤特性的梯度。我们使用茶袋指数（TBI）方案来估算不同空间内枯落物质量损失、分解率（k）和稳定因子（S）的相对变化，并使用结构方程模型（SEM）来确定环境因素与分解之间的关系。与我们的预期不同的是，微观环境因素对观察到的废弃物质量损失、k 和 S 的变化几乎没有解释作用，这表明我们的研究中所包含的变量并不是所研究的苔原地貌中土壤中分解者活动的主要控制因素。我们利用这些意想不到的研究结果，结合现有文献的研究结果，来讨论未来的途径，以提高我们对苔原分解驱动因素的认识，并最终提高我们对整个变暖的北极地区碳循环的认识。

Pinelliacordata (Araceae) is a perennial herb species distributed in China and Japan. Several studies have shown that there are two types of this species, and chromosome counts have shown irregular variation among populations. In this study, we investigated the morphological characteristics, established the chromosome number in root tips, reconstructed phylogenetic relationship based on whole chloroplast genomes, and elucidated biogeographic patterns based on data collected from the Chinese Virtual Herbarium (CVH) and the Plant Photo Bank of China (PPBC) for the two types of P. cordata, including type I (greenish leaf blade) and type II (colored leaf blade). We found stable significant differences in morphometric characteristics (color of the leaf blade abaxially, petiole, spathe and appendix) and the number of chromosomes. The results of the phylogenetic analysis showed that types I and II were located to different places in the evolutionary tree compared to the group. The distribution regions of these types of P. cordata were also slightly different in mainland China. These findings suggested that P. cordata should be divided into P. cordata (type I) and Pinellia discolor (type II, a cryptic species) and the latter is here described as a new species.

Nothapodytes burmanica Y.H.Tan & S.K.Shen, sp. nov. (Icacinaceae) from Kachin State, Myanmar is described and illustrated. It belongs to Nothapodytes due to the lorate hairy petals being connate at the base and a fleshy foliaceous disk divided into five leaflike lobes. Morphological and phylogenetic evidence indicates that it is close to N. pittosporoides. Morphologically, both species have oblanceolate or oblong leaf blades that are adaxially sparsely pubescent, but the new species is distinguished by its leaf base usually being oblique, and the paniculate inflorescence that has more numerous but smaller flowers with shorter petals. Phylogenetic results indicate that N. burmanica is deeply nested within the genus and forms a sister group of N. pittosporoides.
Nothapodytes burmanica Y.H.Tan & S.K.Shen, sp. nov. (Icacinaceae) 产自缅甸克钦邦。该植物属于 Nothapodytes，因为其多毛花瓣在基部合生，肉质叶状花盘分为五个叶状裂片。形态学和系统发生学证据表明，它与 N. pittosporoides 接近。从形态上看，这两个物种的叶片都倒披针形或长圆形，正面有稀疏短柔毛，但新物种的区别在于其叶基部通常偏斜，圆锥状花序的花朵数量更多，但花朵较小，花瓣较短。系统发育结果表明，N. burmanica 在该属中嵌套较深，是 N. pittosporoides 的姊妹群。
