查看更多>>摘要：The taxonomic relationships between Orobanche australis and O. thapsoides are analyzed through the study of the original material. These species are also compared with other morphologically similar ones occurring in the Mediterranean (O. canescens, O. pubescens, O. palaestina, O. amethystea). The lectotype of O. palaestina is designated. From the comparison of these taxa it is evident that O. australis and O. thapsoides refer to the same taxon, to which the name O. australis must be given by priority. The distribution of this species includes Sardinia, Sicily, Peninsular Italy and Southern France. It grows on pastures from the sea level to about 1000 m of altitude, host of Asteraceae. An identification key between the species considered and a distribution map is provided.
查看更多>>摘要：Knautia goecmenii, from Nif Mountain (Izmir) in western Anatolia (Turkey), is described as a new species based on morphological and molecular evidence. Its phylogenetic relationships within the genus are provided based on the nuclearencoded ribosomal internal transcribed spacer (ITS) region. Bayesian and Maximum Likelihood analyses of the molecular data clearly showed that K. goecmenii falls into a clade together with morphologically irrelevant annual species from sections Knautia and Tricheroides. From a morphological perspective, by having a suffrutescent and caespitose habitus with very rich stemmed base (up to 152 stems) without basal leaf rosettes and showing very pale whitish-lilac flowers, K. goecmenii is placed in a unique position within genus Knautia. Both the main morphological features of K. goecmenii and its phylogenetic position make difficult to accommodate it any extant Knautia sections. Finally, the International Union for Conservation of Nature (IUCN) threat category is assessed and observations on the ecology of the only known population of this rare species are noted.
查看更多>>摘要：Geographic novelties of three species of Lamiaceae are newly reported in this paper. Phlomoides zenaidae, previously known only from a few collections from Kazakhstan, is reported from Xinjiang Province, China for the first time. Phlomoides baldschuanica and Nepeta badachschanica, previously only known from Tajikistan, are also newly reported for Uzbekistan. Diagnostic characters, additional descriptions, detailed illustrations, taxonomic comments and conservation status are provided.

Phylogenetic analysis of combined LSU, SSU, ITS, TEF1-alpha and RPB2 sequence data placed the new isolate, Neoascotaiwania aquatica, in the genus Neoascotaiwania within Savoryellaceae. The new taxon is distinguished from other Neoascotaiwania species by its semi-macronematous, uniseptate, subhyaline to pale brown conidiophores and fusiform, 2-septate conidia.
查看更多>>摘要：Conamomum vietnamense, a new species of Zingiberaceae, is described and illustrated from Tay Nguyen (Central Highlands), Vietnam. It is most similar to C. odorum and C. rubidum, but differs in having well-developed stilt roots, elliptic leaf blades, narrowly ovate bracts, abaxially pubescent bracteoles, longer calyx with 2 truncate lobes, broadly obovate to orbicular glabrous labellum, longer filament and glabrous style. Data on distribution, habitat, vernacular name, conservation status and a colour plate of the new species, along with a key to distinguish the species of Conamomum in Cambodia and Vietnam are given.
查看更多>>摘要：In the course of a taxonomic revision of the genus Piptolepis (Vernonieae, Asteraceae), it became clear that P. pseudomyrtus, until now considered a synonym of P. buxoides, should be re-established. It differs from P. buxoides by its habit, leaf shape, number of florets per head, cypsela shape, and length of pappus series. An updated morphological description, geographic distribution, illustration and conservation status of P. pseudomyrtus are provided, as well as a comparative discussion with P. buxoides.

While revising the material for the Flora of the Guianas, the authors uncovered and hereby describe six new species: R. approuaguensis, R. glomerulata, R. graniticola, R. itoupensis, R. jadinii and R. leucocarpa. Most of these are endemic to French Guiana, except R. graniticola which also occurs in Suriname, and R. leucocarpa, recorded also from Suriname and northern Brazil. Additionally, the original description of Rudgea ayangannensis, endemic of Guyana, is emended as it was based on a mixture of two different species, and adjustments are provided in a new description.
