E-mail: [email protected] Aspidistra corniculata is described and illustrated here as a new species from northern Vietnam. In flower structure, A. corniculata resembles A. lubae, A. marasmioides, A. multiflora and A. zinaidae but possesses hornlike connective appendages in stamens that distinguish it from all the other close species. Keywords: connective appendage, taxonomy, Tay Yen Tu, tropical forest Aspidistra Ker Gawler (1822: 628) comprises about 170 species mostly known from southern China and northern Vietnam, including about 60 species endemic to Vietnam (Tillich 2005, 2014, Averyanov & Tillich 2012, 2014, 2015, Leong- Škorničková et al. 2014, Nguyen et al. 2017). Over recent years, many Aspidistra taxa have been described from this diversity center for the genus (Vislobokov 2016, Vislobokov et al. 2016, 2017, Averyanov et al. 2018, Huang et al. 2018, Nong et al. 2018). In the present paper, Aspidistra corniculata is described and illustrated as a new species from Vietnam (Fig. 1). Material and Methods The new species was discovered during fieldwork in Bắc Giang province of Vietnam by N.A. Vislobokov. Living plants, herbarium, and liquid material were collected in October 2018. We measured 24–50 leaf characters and 14–23 floral characters on living plants using a Vernier caliper and a ruler. In the morphological description, the range of variation of each quantitative character is given, followed by the mean value in brackets. Description of the new species Aspidistra corniculata Vislobokov, sp. nov. (Fig. 1) Diagnosis: Aspidistra corniculata is morphologically similar to A. marasmioides and A. multiflora, but differs in longer partly reddish purple filaments with connective appendages, in reddish purple perigone tube and narrowly lanceolate leaf blade. Type:—VIETNAM, Bắc Giang province, Sơn Ðộng district, 6 km South-West from Thanh Sơn Town, Tây Yên Tử National Forest, in the forest, near bank of river, 21˚ 10.627’ N, 106˚ 43.242’ E, alt. 231 m, 21 October 2018, N.A.

Ovary inconspicuous, superior, 3-locular. Fruits unknown. Etymology:—The specific epithet refers to the hornlike connective appendages of stamens. Distribution and ecology:—The species is known only from Tây Yên Tử National Forest, where it grows along the river bank. Phenology:—Aspidistra corniculata flowers in late October. Taxonomic relationships:—In flower structure A. corniculata is similar to A. marasmioides Tillich (2005: 321) and A. multiflora Averyanov & Tillich (2015: 368), but differs for the longer filaments (1.6 mm vs. 1 mm or less) with connective appendages, for the colour of the perigone tube (reddish purple, white at the bottom vs. white or white with purple stripes) and of the filaments (partly reddish purple vs. completely white); A. corniculata is also strongly different in shape of leaf blade (narrowly lanceolate vs. elliptic) and shoot morphology (creeping rhizome with short internodes vs. widely creeping slender rhizome of A. marasmioides and ascending or erect rhizome of A. multiflora). Aspidistra corniculata also resembles A. lubae Averyanov & Tillich (2014: 755) and A. zinaidae Averyanov & Tillich (2012: 8), but differs from these species in shoot habit (creeping rhizome vs. erect stem), in colour of the perigone (reddish purple vs. partly white or greenish), and structure of stamens (elongate filaments spreading horizontally or slightly downward vs. sessile anthers).

Four new species of Aspidistra Ker Gawl. (Asparagaceae) are described and illustrated: A. basalis Tillich, A. columellaris Tillich, A. gracilis Tillich from China, and A. coccigera L.V.Averyanov & Tillich from Vietnam. The application of the name A. longifolia Hook.f. to plants from SE Asia and the intraspecific variability of A. hainanensis W.Y.Chun & F.C.How across its range from peninsular Malaysia to SE China is also discussed. Keywords. Asparagaceae, Aspidistra, China, Malay Peninsula, Thailand, Vietnam Introduction The genus Aspidistra Ker Gawl. (Asparagaceae: Nolinoideae) is distributed from Assam (India) in the west to southern Japan in the east, and from Central China southwards to the Malay Peninsula but the centre of diversity is SE China (Guangxi Province) and adjacent northern Vietnam. During the past three decades the number of known species has increased considerably from 11 in 1980 to more than 100. The recognition of new Aspidistra species is ongoing and stems largely from more widespread collecting, especially in remote areas of SE Asia combined with more detailed study of living plants. Since the publication of a comprehensive key to the genus (Tillich 2008), additional new species have been published (Hou et al.

  • Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes
    Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes Shichao Chen1., Dong-Kap Kim2., Mark W. Chase3, Joo-Hwan Kim4* 1 College of Life Science and Technology, Tongji University, Shanghai, China, 2 Division of Forest Resource Conservation, Korea National Arboretum, Pocheon, Gyeonggi- do, Korea, 3 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, United Kingdom, 4 Department of Life Science, Gachon University, Seongnam, Gyeonggi-do, Korea Abstract Phylogenetic analysis aims to produce a bifurcating tree, which disregards conflicting signals and displays only those that are present in a large proportion of the data. However, any character (or tree) conflict in a dataset allows the exploration of support for various evolutionary hypotheses. Although data-display network approaches exist, biologists cannot easily and routinely use them to compute rooted phylogenetic networks on real datasets containing hundreds of taxa. Here, we constructed an original neighbour-net for a large dataset of Asparagales to highlight the aspects of the resulting network that will be important for interpreting phylogeny. The analyses were largely conducted with new data collected for the same loci as in previous studies, but from different species accessions and greater sampling in many cases than in published analyses. The network tree summarised the majority data pattern in the characters of plastid sequences before tree building, which largely confirmed the currently recognised phylogenetic relationships. Most conflicting signals are at the base of each group along the Asparagales backbone, which helps us to establish the expectancy and advance our understanding of some difficult taxa relationships and their phylogeny.

During the past three decades the number of known species has increased considerably from 11 in 1980 to more than 100 (Tillich & Averyanov 2012), with many novelties reported in last decade from Vietnam (Bogner & Arnautov 2004; Bräuchler & Ngoc 2005; Tillich 2005, 2006; Tillich et al. 2007; Tillich & Averyanov 2008, 2012; Averyanov & Tillich 2012, in press). The total number of known species in Vietnam is currently 37, but as most of the Aspidistra species seem to be stenoendemic, it is expected that with continuing floristic explorations its numbers will grow progressively. The first author has been extensively involved with taxonomy of the genus Aspidistra, and provided a comprehensive key to the genus covering 93 species (Tillich 2008). So when an unidentified Aspidistra species flowered in the living collections of Singapore Botanic Gardens it was brought to his attention by the second author.
