Desmodium auriculatum DC. described from Timor has been recorded also from the Seychelles, Mascarene Islands, Andaman Islands, S. India (Bengal), Bangladesh, and Myanmar. The type of the species is referable to Tadehagi triquetrum (L.) H. Ohashi subsp. triquetrum, but specimens from the added localities are different from the type and no names are available for them. They are newly named here Tadehagi ademae H. Ohashi & K. Ohashi. Desmodium auriculatum recorded from the Philippines is referable to T. triquetrum nothosubsp. philippinense H. Ohashi var. philippinense and var. palawanense H. Ohashi, but the two varieties are regarded here as T. triquetrum subsp. pseudotriquetrum (DC.) H. Ohashi and subsp. triquetrum, respectively.

The genus Amphicarpaea was revised by Ohashi and Ohashi (2016) based mainly on pollen morphology in which Shuteria africana was resurrected from Amphicarpaea africana and the taxonomic position of A. ferruginea was settled in Amphicarpaea. In the present study, those results were reexamined in molecular phylogenetic analyses using chloroplast DNA and nuclear DNA (ITS). Our molecular data show that Shuteria africana is sister to the genus Amphicarpaea, and that A. ferruginea is sister to A. edgeworthii and A. bracteata within the genus. For a consistent systematic treatment with the discrepancy between the results of the pollen morphology and the present molecular study, a new monotypic genus Afroamphica is proposed for Shuteria africana.

A new species of Scutellaria (Lamiaceae), S. kujuensis Kadota & Mas. Saito, is described and illustrated. Scutellaria kujuensis is similar to S. shikokiana Makino but the former differs from the latter by having: triangular-ovate cauline leaves with dark reddish purple bottom surfaces and with dark green upper surfaces variegated along midribs and lateral veins; the absence of bracteoles near basal parts of pedicels; the presence of glandular hairs on corollae, calyces and pedicels; convex lower lips of the corollae with purple spots only on the middle lobes and the early blooming (June). Scutellaria kujuensis is endemic to the Kujū Mountains, Kyushu, southern Japan.

A new species, Impatiens hukaungensis J. Murata & Nob. Tanaka (Balsaminaceae), is described from Kachin State, northern Myanmar. This species is characterized by decumbent stem, oblanceolate leaves, 2-flowered simple raceme, white with purple mottled dorsal petal and purple dolabriform lateral united petals. Morphological characters, including its 2-flowered raceme and short fusiform capsules, as well as results of molecular phylogenetic analyses based on sequences of plastid atpB-rbcL region, suggest this new species belongs to Impatiens sect. Uniflorae Hook. f. & Thomson. It shows a rheophytic habit and grows along streams with high water-level differences.

A new species, Zingiber caudatum Biseshwori & Bipin, from Northeast India is described and illustrated.

The phylogenetic relationships of Coptis quinquefolia Miq. and its related species (Ranunculaceae) were analyzed using nuclear DNA (ITS) and chloroplast DNA (trnL intron and trnL–trnF intergenic spacer) along with morphological variation to clarify the taxonomic status of Coptis quinquefolia var. shikokumontana. The results suggest that plants of the genus Coptis in Shikoku previously classified as C. quinquefolia var. shikokumontana include three taxa; C. quinquefolia var. shikokumontana, C. quinquefolia var. quinquefolia, and C. minamitaniana. In addition, it was also suggested that there is an intermediate type presumed to be a hybrid between the latter two taxa. In Shikoku C. quinquefolia var. shikokumontana is found in the mountains of the central part of Shikoku Island, from Naka-cho (Mt. Tsurugi-san), Tokushima Pref. to Saijo-shi (Mt. Kamega-mori), C. quinquefolia var. quinquefolia is widely distributed in Tokushima, Ehime and Kochi Pref. and C. minamitaniana is known only from the lowlands of central Kochi Pref. Coptis quinquefolia var. shikokumontana is taxonomically revised and additionally circumscribed in this paper.

Lectotypes for Impatiens radiata Hook. f. and I. graciliflora Hook. f. (Balsaminaceae) in the Sino-Himalayan region are designated.

I found a rare mycoheterotrophic plant Gastrodia flexistyloides from Fukuejima Island, Nagasaki Prefecture, Japan. Because G. flexistyloides was previously discovered only from Takeshima Island, Kuroshima Island and Iojima Island, northern Ryukyu, Japan, this habitat represents the northernmost locality of the species.

Garcinia cowa Roxb. (Clusiaceae), collected from Salhesh Phulbari forest, Siraha District, central Nepal, is reported for the first time from Nepal.

A new hybrid of the genus Rubus, R. ×geraniifolius Naruh. & H. Takano, from Honshu, Japan is described. The plant is believed to be a natural hybrid between Rubus crataegifolius and R. pseudoacer. This hybrid differs from R. crataegifolius by 5–7-palmately lobate to palmately parted leaves, lacerate lobes of leaves, and orbicular petals, from R. pseudoacer by prickles on stems, petioles and nerves on lower surface of leaves, slightly hairy on nerves on lower surface of leaves, and pedicels shorter than 15 mm long.
