Aspidistra cylindrica, a new species from southern Vietnam (Kon Tum province), is described and illustrated. The new species possesses a unique combination of cylindrical shape of pistil and shoot system with foliage leaves crowded in groups and not divided into petiole and lamina. Aspidistra cylindrica resembles A. muricata but differs in longer leaves, shorter and wider perigone, shorter pistil, shape and colour of perigone lobes, anther position, and stigma shape. The conservation status of A. cylindrica is assessed. A key for species of Aspidistra in southern Vietnam is provided. © 2016 by the American Society of Plant Taxonomists.

Vietorchis furcata, an achlorophyllous orchid, discovered in southern Vietnam is described and illustrated as new for science. This is the second species of the genus regarded earlier as monotypic. A key for identification of both species of the genus and short notes on their taxonomy and biology are provided. Closely related genera - Vietorchis and Silvorchis are segregated in rank of subtribe Vietorchidinae due to their isolated taxonomical position.

The discovery of Cephalanthera exigua (Orchidaceae), a rare mycoheterotrophic species, is reported from southern Vietnam, Lam Dong province, representing a new specific and generic record for the flora of Vietnam. It also significantly expands the knowledge about the distribution area of this species. Problems of phylogeny, taxonomy and species identity within the Asian group of achlorophyllous species of the genus Cephalanthera are discussed. Morphological description of the Vietnamese plant including first detailed photos of flower structure of Cephalanthera exigua is provided. Thai and Vietnamese plants are compared in terms of flower morphology.

Aspidistra globosa is described and illustrated as a new species from southern Vietnam (Gia Lai province, Kon Ka Kinh National Park). The new species has long erect stem, which is a rare feature in the genus Aspidistra. Aspidistra globosa resembles A. khangii and A. locii in globoid perigone and erect stem, but differs in smaller flowers, color of perigone, position of anthers and orientation of flower. © 2016 Magnolia Press.

Thismia mucronata, a new species of Thismiaceae, is described and illustrated. The species was discovered in 2013 during a botanical survey of a forest in the vicinity of Bao Loc town (Lam Dong province, Southern Vietnam). Thismia mucronata is characterised by vermiform roots and mitriform inner tepals. It differs from related species mainly by the short and appressed to each other appendages of inner tepals, which together resemble a short mucro, the narrow mitre without foveae, the almost horizontal annulus and the absence of interstaminal glands. A key to Vietnamese species of Thismia is provided. © 2014 Magnolia Press.

Thismia puberula, a new species of Thismiaceae, is described and illustrated. The species was discovered in 2014 during botanical survey of Chu Yang Sin national park (Dak Lak province, Southern Vietnam). Thismia puberula possesses vermiform roots and mitriform inner tepals. It is most similar to T. angustimitra, T. mirabilis, T. mucronata and T. okhaensis. The new species differs from related species mainly by dome-shaped annulus with delimited vertical and horizontal parts covered by hairs, broad mitre with foveae, inner mitre surface covered by papillate trichomes, and presence of interstaminal glands. An updated key to Vietnamese species of Thismia is provided. © 2015 Magnolia Press.

Floral morphology, anatomy and development are examined in Xyris grandis (Xyridaceae: Poales), with an emphasis on petal and sepal organogenesis and vasculature. Xyris is one of relatively few monocots in which the perianth is differentiated into two distinct whorls (here termed a double perianth). Xyris also possesses highly unusual perianth vasculature, with each petal being supplied by three veins and each sepal by a single vein, compared with the opposite condition in most other angiosperms with a double perianth. However, perianth development in X.grandis shows a pattern that is typical for monocots, with petals not markedly delayed in development. Xyris grandis is also remarkable for its petal aestivation, with each petal surrounding a stamen and two branches of adjacent staminodes, a type that is not reported for other Xyridaceae and may contribute to secondary pollen presentation. The results are discussed in the context of the diversity of a double perianth in monocots, compared with eudicots. Based on current data, our preferred hypothesis is that meristic differences are at least partly responsible for the apparently widespread occurrence of three-traced petals in monocots. © 2012 The Linnean Society of London.
