Within Araliaceae, at least four groups are recognized to have significant deviations from the typical euasterid flower groundplan: (1) Asian Schefflera clade (incl. Tupidanthus), (2) Plerandra group, (3) Tetraplasandra and (4) Osmoxylon. The main trends of flower structure variation are: reduction of calyx, increase in number of stamen whorls, inc...
Flowers of Tupidanthus show an extreme case of floral polymery among asterids. Floral development and gynoecium structure have been examined. The
floral meristem has a complex folded shape. The tiny calyx is initiated as a continuous ring primordium. The corolla is initiated
as a lobed ring and develops into a calyptra. All stamen primordia appear...

Alexey Borisovich Shipunov Alexey Shipunov was an outstanding person in many ways. An accomplished botanist, he was also a programmer and a teacher. One of his many impressive features was his universality. Indeed, he was interested in a vast range of things, and his professional scope accordingly tended to be universal: for example, as a taxonomis...
A synopsis of the orchid genus Didymoplexiella is presented for Cambodia, Laos and Vietnam.

The monotypic genus Pseudomarrubium is perhaps the most poorly understood taxon within the subfamily Lamioideae (Lamiaceae). While advances in molecular phylogenetics have clarified the phylogeny and taxonomy of Lamioideae, the systematic placement of Pseudomarrubium remains unclear, as it has never been tested using molecular phylogenetic analyses...

The mycoheterotrophic genus Thismia shows a great number of structural and ecological traits which are rare or unique for angiosperms. Pollen morphology of this genus is still poorly known. Pollen of Thismia was reported to be porate with one to several pores. Position of the pores is unknown, and therefore, the pollen type has not been established...
Pseudomonomerous gynoecia with three (or four) carpels are unknown in the species-rich core group of Apiales, but this condition is shared by three species-poor families (Pennantiaceae, Torricelliaceae, Griseliniaceae) that form the basal grade of the order. Testing a hypothesis on the ancestral nature of carpel dimorphism in Apiales requires compa...
The plant family Balanophoraceae consists entirely of species that have lost the ability to photosynthesize. Instead, they obtain nutrients by parasitizing other plants. Recent studies have revealed that plastid genomes of Balanophoraceae exhibit a number of interesting features, one of the most prominent of those being a highly elevated AT content...
The present work is an effort to untangle the taxonomy of Phlogacanthus pulcherrimus, a poorly known species reported here for the first time for the flora of Vietnam. Fresh specimens of this species were collected from three localities in Southern Vietnam. They provided new insights to its appearance and morphology. Phlogacanthus pulcherrimus can...
Begonia xuansonensis, a new species from northern Vietnam, is described and illustrated. The new species is characterized by reddish-orange to orange tepals, which is a rare type of flower coloration in asian species of the genus.

Aspidistra thuongiana is described and illustrated as a new species from the South Central Coast region of Vietnam. The new species has bright yellow flower and a slender pistil with a minute stigma. It is morphologically close to A. longipedunculata, but differs in shorter peduncle, bowl-shaped (vs. campanulate) perigone, shorter ovate (vs. oblong...
Heterotrophic plants provide intriguing examples of reductive evolution. This is especially evident in the reduction of their plastid genomes, which can potentially proceed toward complete genome loss. Several milestones at the beginning of this path of degradation have been described; however, little is known about the latest stages of plastome re...
Thismia is characterized by an exceptionally complicated floral morphology that is currently not understood properly. In the taxonomic literature, descriptive rather than morphological terms are often applied to parts of the flower in Thismia, relating to the general appearance of the floral organs instead of their precise homologies. Precise under...

The monocot family Triuridaceae is a morphological misfit with respect to several traits of floral morphology, including the uniformly apocarpous polymerous gynoecium and the famous inside-out flowers of Lacandonia. Although Triuridaceae are crucially important for understanding the floral evolution of Pandanales and angiosperms in general, signifi...

The plant family Balanophoraceae consists entirely of species that have lost the ability to photosynthesize. Instead, they obtain nutrients by parasitizing other plants. Recent studies have shown that plastid genomes of Balanophoraceae have a number of interesting features, one of the most prominent of those being a tremendous AT content close to 9...
