　概要を見る

Two novel species of Neolitsea (Lauraceae), Neolitsea kraduengensis Tagane & Yahara and N. vuquangensis Mitsuyuki & Yahara, are described and illustrated. Neolitsea kraduengensis occurs in Phu Kradueng National Park, Loei Province, Northeast Thailand. Neolitsea vuquangensis is in Vu Quang National Park, Ha Tinh Province, North Central Vietnam. Morphological differences of the two species from similar species are presented. A phylogenetic tree reconstructed from ITS sequences supports their distinctiveness. Two phenotypically similar species, Neolitsea aurata and N. vuquangensis , with dense golden yellow hairs on the leaf blades, are not sister to each other.

　概要を見る

Herein, Mussaenda recurvata, a new species from Hon Ba Nature Reserve, southern Vietnam, is described and illustrated. This species is morphologically similar to M. longipetala, distributed from southern China to northern Vietnam, in having recurved stipules and densely pilose and puberulent hairs throughout, but differs in its strongly recurved calyx lobes, a shorter corolla tube, and ovate corolla lobes. The species is morphologically heterostylous and it appears to be functionally dioecious. An updated key to Mussaenda species in Vietnam, Laos, and Cambodia is also provided.

Morphological and Molecular Phylogenetic Analyses of <i>Geranium yesoense </i>(Geraniaceae) in Japan

Acta Phytotaxonomica et Geobotanica ( 日本植物分類学会 )  68 ( 3 ) 129 - 144   2017年 [ 査読有り ]

掲載種別: 研究論文（学術雑誌）

　概要を見る

<i>Geranium yesoense </i>(Geraniaceae) includes several varieties that are mainly discriminated by two morphological features, namely, the degree of leaf incision and the density of spreading hairs on the sepals, but these features have never been objectively quantified. To clarify whether these features can truly discriminate varieties, we analyzed leaf shape and sepal pubescence, and conducted a molecular phylogenetic analysis using nuclear and chloroplast DNA. Our morphological analyses showed some trends in leaf morphology and density of hairs, but failed to identify any groupings that could be clearly distinguished on the basis of these features. Our molecular analysis recognized <i>G. yesoense </i>as a distinct taxon, but did not support the existence of subgroups within the species. We conclude that <i>G. yesoense </i>must be treated as a single taxon with some tendency toward morphological variation depending on locality and habitat.

Lysimachia kraduengensis (Primulaceae), a new species from northeastern Thailand

Phytotaxa ( Phytotaxa )  289 ( 1 ) 69 - 76   2016年12月 [ 査読有り ]

掲載種別: 研究論文（学術雑誌）

　概要を見る

A new species of Primulaceae from Thailand, Lysimachia kraduengensis, is described and illustrated. It is morphologically similar to L. engleri, L. lancifolia, L. laxa and L. sikokiana in having solitary and axillary flowers, a yellow corolla, relatively long pedicels and basifixed anthers. The new species can be distinguished by the combination of its height, leaf texture, petiole, calyx and anther length, and brown coloration on the flowers. In addition, the conservation status, an updated key to Lysimachia species in Thailand, and discussion of the systematic placement of the new species based on the trnL-F marker of chloroplast DNA are provided.
