Cirsiumtatakaense (Compositae), a new species from Taiwan.

ABSTRACT: A new species of Cirsium, Cirsiumtatakaense Y.H.Tseng & C.Y.Chang, from central-southern Taiwan is described and illustrated. This species is similar to C.kawakamii Hayata in leaf shape, achene and chromosome number (2n = 64), but can be readily distinguished from C.kawakamii by the narrower leaf lobes, usually higher number of florets and phyllaries, the purplish-red corolla (vs. white) and larger pollen grains. A key to the species of Cirsium in Taiwan is also presented.

Cirsiumtaiwanense (Compositae, Cirsiumsect.Onotrophe, subsect. Australicirsium), a new species from Taiwan.

Project description:A new species of Cirsium, C.taiwanense Y.H.Tseng & Chih Y.Chang from central-northern Taiwan is reported in this article. This species is similar to C.hosokawae Kitam. in having a densely cobwebby abaxial leaf surface, but differs in its yellow (vs. vivid purplish red) corolla and the angle between the midrib and the lateral veins of the leaf, which is acute as opposed to nearly at a right angle in C.hosokawae. Cirsiumtaiwanense has 2n = 32 chromosomes, which is different from the other species in the Taiwanese subsect. Australicirsium Kitam. (2n = 34). An identification key to the Cirsium taxa of Taiwan is presented.

Two new species of the Andean genus Xenophyllum (Senecioneae, Compositae).

Project description:Two new species of Xenophyllum are described from the Andes, X. funkianum sp. nov. from Ecuador and X. lorochaqui sp. nov. from northwestern Argentina. Both species are compared with the morphologically closest taxa and useful characters for their proper identification are provided. Detailed illustrations and distribution maps are also presented, as well as pictures of living plants when available.

Gymnanthemum koekemoerae (Compositae, Vernonieae), a new species from South Africa.

Project description:A new species of Gymnanthemum (Compositae, Vernonieae) from South Africa is described. It can be distinguished from other species in the genus by the five-flowered capitula and widely obtuse leaf blades.

Senecio festucoides (Senecioneae, Compositae), a new species from northern Chile.

Project description:Senecio festucoides is described from northern Chile. The new species is morphologically similar to the discoid caespitose Andean species and belongs to the subgroup displaying yellow corollas and yellowish anthers and style branches. It is characterized by a weak, not self-supporting stem, narrowly linear leaves, long pedunculate capitula with (17-)21 involucral bracts, and minutely papillose achenes. Among other characters, the color of the corollas, anthers, and style branches and the number of involucral bracts differentiate it from S. scorzonerifolius, which is the morphologically closest species. The new species thrives in the desertic Puna ecoregion and grows amongst tufts of Festuca chrysophylla (Poaceae). Detailed pictures of living plants are provided, as well as a distribution map and a dichotomous key to the discoid caespitose Senecio species from northern Chile.

Zingiber chengii (Zingiberaceae), a new species from Taiwan.

Project description:In this article, we describe a new species, Zingiber chengii Y.H. Tseng, C.M. Wang & Y.C. Lin, discovered on a rock cliff of Youluo riverside in northern Taiwan. This species is easily distinguished from other known congeners by its grass-like leaves, spikes composed of a few sterile bracts, and seeds one-third enveloped by the aril. Color illustrations, line drawings, and a key to species of Zingiber in Taiwan are provided as well as comparative morphology in relation to its allied species, geographical distribution, and conservation status.

A new species of Encelia (Compositae, Heliantheae, Enceliinae) from the southern Baja California Peninsula.

Project description:Here, we describe and illustrate Enceliabalandra sp. nov., a new species of Compositae from the Baja California Peninsula. It is rare and known only from the rocky hills around Puerto Balandra and Pichilingüe, inside the bay of La Paz, in the State of Baja California Sur, Mexico. We determine that this new species has affinities with Encelia, based on its suffruticose woody habit, neuter ray florets and compressed disc cypselae with a cleft apex. The taxonomic placement within Encelia is supported by nuclear ribosomal sequence data from two regions, ITS and ETS. We also present detailed photographs, a conservation assessment and a dichotomous key to the Encelia of the southern Baja California Peninsula. Finally, we discuss the uniqueness of Enceliabalandra amongst peninsular Encelia and its potential significance for understanding the enigmatic biogeography of this ecologically important genus.

A new species of Stigmatomma from Taiwan (Hymenoptera, Formicidae, Amblyoponinae).

Project description:Stigmatomma is the most speciose ant genus in the subfamily Amblyoponinae. In the present paper, the worker caste of a new species is described, S. luyiaesp. n., which was collected from a soil sample in a subtropical evergreen broad-leaved forest in Taiwan. An identification key to the females of Stigmatomma species with 11 antennomeres occurring in Asia is also provided.

Rubuspuyumaensis, a new species of Rosaceae from Taiwan.

Project description:BackgroundThe genus Rubus L. (Rosaceae), comprising approximately 750 species and classified into 12 subgenera, is distributed worldwide and is one of the largest plant genera. In Taiwan, Rubus comprises 41 taxa, including 35 species, three varieties and three hybrids. Amongst the genus Rubus, the species, previously recorded as R.howii in Taiwan, was misidentified and this study recognised it as a new species.New informationDue to its distribution mainly in south-eastern Taiwan, we named this new species as Rubuspuyumaensis, after the local aborigine tribe Puyuma. Taxonomic descriptions and colour photographs of the new species are provided to assist in identification. R.puyumaensis is most similar to R.howii and R.refractus. They can be distinguished by the colour of young leaves, leaf shape, arrangement of florets, trichomes of inflorescences, size of sepal lobes, petal colour, types and trichomes of filaments and the length of stamens and pistils.

Bolbitis lianhuachihensis (Dryopteridaceae), a new species from Taiwan.

Project description:A new species of Bolbitis, B. lianhuachihensis sp. nov., was found in central Taiwan. It most resembles B. virens var. compacta and B. hainanensis. A phylogenetic tree of Taiwanese and other Asian species of Bolbitis species supports the recognition of the new species. Morphologically, the combination of anastomosing venation and fewer sterile pinnae are critical characters to discriminate B. lianhuachihensis from other Taiwanese Bolbitis species. Bolbitis lianhuachihensis can be further distinguished from B. virens var. compacta and B. hainanensis by having lanceolate sterile pinnae and absent or fewer free veinlets in small areoles of sterile pinnae. The morphological descriptions, illustration, ecology and distribution of the new species are presented. A key to all Taiwanese Bolbitis is also provided.
