Two species are newly reported for the Arabian Peninsula and eight new records for the Sultanate of Oman. Brief comments are provided on the phytogeography and ecology of these species. Most new records have been made from the botanically very poorly known or unexplored mountainous areas of northern Oman, including Musandam and poorly collected areas in Dhofar. These additional records raise the total number of known taxa in the national flora of Oman to 1417.
阿拉伯半岛新报告了两个物种,阿曼苏丹国新记录了八个物种。本文对这些物种的植物地理学和生态学进行了简要评述。大多数新记录都来自植物学上知之甚少或未经勘探的阿曼北部山区,包括穆桑达姆和佐法尔采集较少的地区。这些新增记录使阿曼国家植物区系中的已知分类群总数增至 1417 个。

A TAXONOMIC REVISION OF THE MADAGASCAR-ENDEMIC GENUS BEMANGIDIA (SAPOTACEAE), WITH DESCRIPTION OF A SECOND SPECIES 马达加斯加特有的贝曼吉德属(无患子科)的分类学修订,并描述了第二个种

Bemangidia L.Gaut. (Sapotaceae) is a genus endemic to a restricted area in the southeastern lowland moist evergreen forests of Madagascar. It was published in 2013 to accommodate an undescribed species, Bemangidia lowryi L.Gaut., which showed a combination of characters unique in the family Sapotaceae. At the time of description, three atypical collections from the same locality but growing on a ridge, slightly higher in altitude, were already known. Although matching well with the Bemangidia genus, they were phenotypically different from B. lowryi and were therefore not included in the species description. In the present study, we evaluate whether these specimens correspond to a new species, using a combination of morphological and genetic data based on 638 nuclear genes. The results show that Bemangidia contains two lineages, each one corresponding to a different morphology, with a genetic branch length similar to those observed among species pairs in other genera of Sapotaceae. We conclude that the genetic and  morphological differences are sufficient to consider the two lineages as two distinct species. Consequently, the genus is here revised and a second species described.
Bemangidia L.Gaut.(无患子科)是马达加斯加东南部低地常绿湿润森林中一个有限地区特有的属。该属于 2013 年发表,以容纳一个未被描述的物种,即 Bemangidia lowryi L.Gaut.,该物种显示出无患子科特有的特征组合。在描述该物种时,人们已经知道来自同一地点但生长在海拔略高的山脊上的三个非典型采集物。虽然与 Bemangidia 属非常吻合,但它们在表型上与 B. lowryi 不同,因此未被纳入物种描述。在本研究中,我们结合形态学和基于 638 个核基因的遗传数据,对这些标本是否对应于一个新物种进行了评估。结果表明,Bemangidia 包含两个世系,每个世系对应不同的形态,其遗传分支长度与山榄科其他属的物种对中观察到的分支长度相似。我们的结论是,遗传和形态上的差异足以将这两个系视为两个不同的种。因此,我们在此对该属进行了修订,并描述了第二个种。

A TIME-CALIBRATED PHYLOGENY OF VERBESINA (HELIANTHEAE – ASTERACEAE) BASED ON NUCLEAR RIBOSOMAL ITS AND ETS SEQUENCES 基于核核糖体序列和ERS序列的verbesina( heliantheae - asteraceae)的时间校准系统发育

Verbesina L. is a genus of the tribe Heliantheae, subtribe Verbesininae (Asteraceae), with distribution in the Americas, where Mexico and the Andes harbour the richest concentration of species. The approximately 325 species in the genus are shrubs, subshrubs, trees and rarely herbs. Despite its high species diversity and biogeographical importance, the only available phylogenetic hypothesis for Verbesina was based on chloroplast DNA restriction site data. In the present study, nuclear ITS and ETS DNA sequence data were used with an expanded taxon sampling, particularly among the South American Verbesina species, to improve phylogenetic resolution and support, clarify infrageneric relationships, and resolve biogeographical questions in the genus. The results of our new analysis corroborate the monophyly of Verbesina, but its current classification into 12 taxonomic sections, based on morphological characters such as phyllotaxis, head size, corolla colour, and presence of ray flowers, is not congruent with the molecular phylogeny, in which most sections are polyphyletic. We also show that Verbesina diverged in the late Miocene of North America, about 8 Ma. At least two independent Pleistocene dispersals into South America across the Isthmus of Panama and along the Southern Andes are evident, beginning around 3.23 Ma (1.27–3.23 Ma) in the Middle Pliocene, and resulting in an extra-Amazonian distribution of the genus inSouth America. Diversification in South America began around 2.83 Ma with occupation of the Andes. Colonisation of Brazil is  estimated to have occurred around 2.15 Ma, from Andean lineages.
马鞭草属(Verbesina L.)是菊科马鞭草亚科马鞭草属(Heliantheae)的一个属,分布于美洲,其中以墨西哥和安第斯山脉的物种最为丰富。该属的约 325 个物种为灌木、亚灌木、乔木,很少有草本植物。尽管其物种多样性很高,在生物地理学上也很重要,但 Verbesina 唯一可用的系统发育假说是基于叶绿体 DNA 限制位点数据。在本研究中,我们使用了核 ITS 和 ETS DNA 序列数据,并扩大了分类群取样范围,尤其是南美洲 Verbesina 物种之间的取样范围,以提高系统发育的分辨率和支持率,澄清属下关系,并解决该属的生物地理学问题。我们新的分析结果证实了 Verbesina 的单系性,但目前根据植轴、头部大小、花冠颜色和是否有射线花等形态特征将其划分为 12 个分类单元的做法与分子系统发生不一致,在分子系统发生中,大多数单元都是多系的。我们还表明,Verbesina 在北美中新世晚期(约 8 Ma)分化。从中新世大约 3.23 Ma(1.27-3.23 Ma)开始,至少有两次独立的更新世扩散,穿过巴拿马地峡和沿南安第斯山脉进入南美洲,导致该属在南美洲亚马孙河外分布。南美洲的多样化始于公元前 2.83 年左右,安第斯山脉被占领。据估计,巴西的殖民化发生在公元前 2.15 年左右,来自安第斯山系。

The only Mahonia species found in Cuba is investigated. Although known since the nineteenth century, it has previously been identified as Mahonia tenuifolia (or its synonym Berberis fraxinifolia), otherwise found in Mexico. The Cuban species is shown to differ inter alia from the Mexican species by its leaf shape and texture, shorter racemes and pedicels, and greater number of ovules. The habitat and distribution of the species are described. Mahonia tenuifolia and Berberis fraxinifolia are also lectotypified.
经调查,这是古巴发现的唯一 Mahonia 树种。虽然早在十九世纪就已为人所知,但它之前一直被认定为 Mahonia tenuifolia(或其异名 Berberis fraxinifolia),在墨西哥也有分布。研究表明,古巴种与墨西哥种的区别主要在于叶形和质地、总状花序和花梗较短以及胚珠数量较多。报告还描述了该物种的栖息地和分布情况。还对 Mahonia tenuifolia 和 Berberis fraxinifolia 进行了分类。

A new micro-endemic species of Rhododendron is described and illustrated from botanical expeditions to the Victoria-Anepahan  Mountain Range on the island of Palawan. It closely resembles Rhododendron wilkiei but differs in having leaves with laminae that are  narrowly elliptic-oblanceolate, have adaxially indistinct venation, and are arranged in 4–8 active and mostly terminal pseudowhorls  along the length of the stem; bracts without scales on the margin; yellow flowers with a red corolla tube interior that is densely hairy  towards the base; and hairy anther filament bases. Morphological and geographical data place the species in Rhododendron sect.  Schistanthe. The new species, together with a first record of Rhododendron vidalii on Palawan as part of this research, represent the  tenth and eleventh members of this genus recorded from the island. A revised key to the Palawan species of Rhododendron is provided.
通过对巴拉望岛维多利亚-阿内帕汉山脉的植物考察,描述并说明了杜鹃花的一个微型特有新种。该种杜鹃花与威尔基杜鹃花(Rhododendron wilkiei)非常相似,但不同之处在于:叶片呈倒披针形狭椭圆形,正面脉序不明显,沿着茎的长度排列成 4-8 个活动的假轮,大多为顶生;苞片边缘无鳞片;花黄色,花冠筒内部红色,基部密生毛;花药花丝基部有毛。形态学和地理数据将本种归入杜鹃花科。 Schistanthe。该新种以及首次在巴拉望岛记录到的 Rhododendron vidalii 是本研究的一部分,是该岛记录到的该属的第 10 个和第 11 个成员。本报告还提供了巴拉望杜鹃花物种的修订检索表。
