A new subalpine species of Bufonia sect. Longipedicellata from the Zagros Mountains in west Iran is described and illustrated here. It colonizes mountain slopes with gravelly, stony, and scree substrates in one locality of Chaharmahal and Bakhtiari province, preferably with a western and north‐west orientation, at elevations between 2700 and 3100 m a.s.l. The new species, B. darvishii, is diagnosed against the morphologically similar B. macrocarpa. The two species share similarities such as filiform and long pedicels, a lax panicle‐cyme inflorescence, distribution pattern of trichomes, and long peduncles. However, the new species stands out with semi‐shrub life form, its greater height, retention of the previous year's stems, cymes bearing more flowers, orbicular petals, larger petals, a broadly ovate ovary, larger sepals with more pronounced nervation, shorter pedicels, larger flowers, etc. Bufonia darvishii is proposed to be Critically Endangered (CR) following the guidelines of the IUCN.
本文描述了伊朗西部扎格罗斯山脉的一个亚高山新种 Bufonia sect.Longipedicellata 的一个亚高山新种。新种 B. darvishii 是根据形态上相似的 B. macrocarpa 诊断出来的。这两个物种有相似之处，如丝状的长花梗、疏松的圆锥花序、毛状体的分布模式和长花序梗。不过，新种以半灌木的生活形态、更高的高度、保留前一年的茎、聚伞花序开更多的花、圆形花瓣、更大的花瓣、宽卵形的子房、更大的萼片和更明显的叶脉、更短的花梗、更大的花等特点脱颖而出。根据世界自然保护联盟的指导方针，Bufonia darvishii 被列为极危物种。

The beneficial effects of smoke and its constituents, karrikinolide (KAR1) and cyanohydrin glyceronitrile, on the germination of Mediterranean lowland species are well‐documented. However, very little is known about the role of these signals on the germination of plants at higher altitudes. In addition, lignin‐derived chemicals, such as syringaldehyde (SAL), have recently been proposed as overlooked cues for smoke‐induced germination. To address these gaps in the literature, we investigated the effects of smoke‐water and SAL on the germination of 10 midland species growing on serpentine soils. We also sought to determine whether SAL interacts with KAR1 and/or mandelonitrile (MAN, a cyanohydrin) to enhance seed germination. The results show that smoke‐water significantly improved the germination of three species (Barbarea duralii, Digitalis cariensis and Turritis laxa). SAL, on the other hand, had no positive effect on the germination of the 10 species tested. Furthermore, three smoke‐sensitive species and Verbascum cariense responded to KAR1 and/or MAN. Finally, SAL did not exert any synergistic effects on germination in interaction with KAR1 and MAN. In conclusion, we provide evidence that smoke is an important germination cue also for Mediterranean midland species. Moreover, SAL did not play a role in stimulating germination in smoke‐sensitive species, either independently or in combination with other smoke chemicals.
烟雾及其成分卡里基内酯（KAR1）和氰氢甘油腈对地中海低地物种发芽的有利影响已得到充分证实。然而，这些信号对高海拔植物发芽的作用却知之甚少。此外，木质素衍生化学物质，如丁香醛（SAL），最近也被认为是烟雾诱导发芽的被忽视的线索。为了填补这些文献空白，我们研究了烟水和 SAL 对生长在蛇纹石土壤上的 10 种中部地区物种发芽的影响。我们还试图确定 SAL 是否与 KAR1 和/或曼德拉腈（MAN，一种氰醇）相互作用，从而提高种子萌发。结果表明，烟水能显著提高三种植物（Barbarea duralii、Digitalis cariensis 和 Turritis laxa）的萌发率。另一方面，SAL 对测试的 10 个物种的萌发没有积极影响。此外，三个对烟雾敏感的物种和 Verbascum cariense 对 KAR1 和/或 MAN 有反应。最后，在与 KAR1 和 MAN 的相互作用中，SAL 没有对萌芽产生任何协同效应。总之，我们提供的证据表明，烟雾也是地中海中部地区物种的重要萌发线索。此外，无论是单独使用还是与其他烟雾化学物质结合使用，SAL 对烟雾敏感物种的萌芽都没有刺激作用。

A newly discovered species, Stereochilus linearifolius (Vandeae, Orchidaceae), which was found in Maguan (Yunnan Province, China), is described and illustrated. Detailed morphological examination revealed that S. linearifolius exhibits similarities to S. dalatensis, however, it distinguishes itself in terms of plant size, leaf dimensions (length and width), sepal width, spur shape, midlobe shape, as well as the coloration of lip, anther cap and stigma.

We studied Rubus wahlbergii and related species in R. sect. Corylifolii, primarily in Sweden, using DNA microsatellites. The results show that the material can be divided into three species: R. wahlbergii s.s. which occurs along the Swedish coast from Bohuslän to Uppland, R. nordicus which occurs on the western coast all the way south to north‐western Skåne, and a previously unrecognized taxon which we here describe as R. wahlbergioides. The latter has scattered localities in Halland, Skåne, Blekinge, Öland and Småland, but is common around Kivik in Skåne and Kalmar in Småland. It is characterised by leaves that are without felt underneath, terminal leaflets with a somewhat more triangular shape and coarser serration than those of R. wahlbergii and also has more glands on the stem and the inflorescence. In the northern part of the distribution, R. nordicus is easily distinguished morphologically from R. wahlbergii, e.g. by a strong tendency to form 7‐foliolate leaves, but in Skåne and Halland, the two species are harder to distinguish. Still, genetically R. nordicus is more similar to R. sordirosanthus than to R. wahlbergii s.s.
我们主要在瑞典利用 DNA 微卫星对 Rubus wahlbergii 和 R. sect.Corylifolii 中的相关物种。结果表明，这些材料可分为三个物种：nordicus 分布在西海岸，一直向南延伸到斯科内省西北部，还有一个以前未被发现的类群，我们在此将其描述为 R. wahlbergioides。后者在哈兰德、斯科纳、布莱金、厄兰和斯莫兰有零星分布，但在斯科纳的基维克和斯莫兰的卡尔马附近很常见。它的特点是叶片下面没有毡，顶生小叶的形状略呈三角形，锯齿比 R. wahlbergii 更粗，茎和花序上的腺体也更多。nordicus 与 R. wahlbergii 很容易从形态上区分开来，例如它们都有形成 7 小叶的强烈倾向，但在斯科纳省和哈兰德省，这两个物种就很难区分了。不过，从遗传学角度来看，诺迪克斯（R. nordicus）与索尔迪罗桑特斯（R. sordirosanthus）的相似度要高于华尔贝里（R. wahlbergii s.s.）。

Iris luojiensis Z.Y. Wang, H.W. Huang and R. Li sp. nov. from southwest China is described and illustrated. This species occurs on shrub slopes in mountainous regions of southwest China. Iris luojiensis is morphologically similar to Iris japonica Thunb., Iris calcicola Z. C. Lu, Z.P. Huang and Yan Liu and Iris wattii Baker, but easily distinguished from them by its bluish‐violet flowers, 3–6 flowering‐stem branches, leaf size, particularly the upper leaves, and by only having two to three (seldom one) flowers per bract. A phylogenetic analysis based on the complete plastid genome supports the separation of I. luojiensis from other morphologically related species. According to morphological and molecular evidence, I. luojiensis can be placed in the I. sect. Lophiris.
来自中国西南部的新种鸢尾（Iris luojiensis Z.Y. Wang, H.W. Huang and R. Li sp.nov.）被描述并图解。本种分布于中国西南山区的灌木斜坡上。洛吉鸢（Iris luojiensis）在形态上与鸢尾（Iris japonica Thunb.）、鸢尾（Iris calcicola Z. C. Lu, Z.P. Huang and Yan Liu）和鸢尾（Iris wattii Baker）相似，但由于其花为蓝紫色，花茎分枝为 3-6 个，叶片大小（尤其是上部叶片）以及每个苞片只有 2-3 朵花（很少为 1 朵），因此很容易与它们区分开来。基于完整质粒基因组的系统发育分析支持将 I. luojiensis 与其他形态上相关的物种区分开来。根据形态学和分子证据，I. luojiensis 可归入 I. sect.Lophiris.
