The Dryopteris erythrosora complex (Dryopteridaceae; subg. Erythrovariae sect. Erythrovariae Fraser- Jenk.) contains many apogamous species showing large morphological and genetic variation. This study reports two new tetraploid apogamous species: Dryopteris tsushimense (D. caudipinna + D. chinensis) and D. subtsushimense (D. chinensis + D. tsoongii). Their parents were postulated by use of a plastid DNA (rbcL) and nuclear DNA (G6PD) marker. Dryopteris tsushimense is similar to D. chinensis in its fresh green lamina, but differs in having narrowly triangular lamina. Dryopteris subtsushimense is also similar to D. chinensis in its fresh green lamina, but it differs in being evergreen lamina and in having scales with a serrated margin. This is the first report of maternal ability in natural populations of apogamous ferns.
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.
Borneo is known to harbor the greatest species diversity of the mycoheterotrophic genus Sciaphila (Triuridaceae) and is home to 11 species, including five endemics. Here, another undescribed Sciaphila species, S. lambirensis, which was discovered during a botanical survey in Lambir Hills National Park (Sarawak, Borneo, Malaysia) is reported along with a detailed morphological account. Sciaphila lambirensis is similar to S. brevistyla in having six equal perianth segments with a swollen apex bearing long hairs in both staminate and carpellate flowers. However, it is easily distinguishable by the secund arrangement of the flowers and the pedicel slightly recurved at its apex. A key to the species of Sciaphila in Borneo is provided.
Trachyandra mira, a new species of sect. Trachyandra (Asphodelaceae) from South Africa, is described and illustrate. Trachyandra mira resembles T. kamiesbergensis, but differs in its pale brown to creamy white (vs. bright red) roots, shorter pedicels 2–3.5 mm long (vs. to 10 mm long), broader bracts 2–3.5 × 3–4 mm (vs. 3–4 × 1–2 mm) and ellipsoid ovary ca. 2 × 1 mm (vs. globose, 1–1.5 mm across).
Sonerila aiensis C. W. Lin (Melastomataceae) from southwestern Sarawak is described and illustrated as new. It resembles S. hirtella Cogn., but differs in being appressed sericeous on the midrib and lateral veins on the adaxial surface (vs. hirtellous), of the lamina, pedicel ca. 1.5 (vs. 2–4) mm long and sparsely glandular hairy (vs. densely hirtellous), to 15 (vs. 1–4) flowers per inflorescence, and hypanthium glandular-hispid (vs. hirtellous).
A new peloric form of the mycoheterotrophic orchid, Neottia kiusiana T. Hashim. & Hatus. f. conformis Suetsugu (Orchidaceae), is described based on specimens in the herbarium of Kagoshima University (KAG), Kagoshima, Japan. The habitat where the specimen was collected, Takakuma area, Kagoshima Prefecture, represents the southernmost locality of Neottia kiusiana.
Parietaria micrantha was newly recorded in Taiwan and is described for the first time in this study; its pollen morphology was also examined. The taxonomic status of Parietaria taiwania was also investigated. The original publications, type specimens, and living plants of Parietaria taiwania and Pouzolzia taiwaniana were examined, resulting in the discovery that the two species are conspecific and belong to Pouzolzia. Parietaria taiwania is therefore treated as a synonym of Pouzolzia taiwaniana.
Gastrodia albida T. C. Hsu & C. M. Kuo is reported from Yaku Island, Kagoshima Prefecture, Japan, as a new record of this species to Japan. Traits of G. albida are described and illustrated based on specimens collected on Yaku Island. This species has a unique combination of characters, such as only partly united lateral sepals, curved perianth tube and white triangular lip. The population on Yaku Island differs from the population at the type locality in Taiwan in having widely opening lateral sepals and a flat-topped disk of the lip and epichile slightly 2-ridged along the margin.
