Grasses (Poaceae) comprise c . 11 800 species and are central to human livelihoods and terrestrial ecosystems. Knowing their relationships and evolutionary history is key to comparative research and crop breeding. Advances in genome‐scale sequencing allow for increased breadth and depth of phylogenomic analyses, making it possible to infer a new re...
Dendrocalamus brandisii is a high-quality bamboo species that can be used for both bamboo shoots and wood. The nutritional components and flavors of D. brandisii vary from different geographical provenances. However, the unique biological characteristics of bamboo make morphological classification methods unsuitable for distinguishing them. Althoug...
Neomicrocalamus and Temochloa are closely-related genera for which ‘inflorescence’ structures were incompletely understood and difficult to reconcile. After re-examining the inflorescence morphology, the so-called ‘spikelets’ of both genera as described should instead be recognised as pseudospikelets with mostly inactive axillary buds. The new bamb...
Bambusa lako, known in horticulture as Timor black bamboo, described without flowering material initially, is a common ornamental bamboo in Southeast Asia because of its moderate size and purplish-black culms when matured. During specimen examination at the Herbarium of the Singapore Botanic Gardens, a flowering collection of B. lako came to our at...
Polyploidy is a significant mechanism in eukaryotic evolution and is particularly prevalent in the plant kingdom. However, our knowledge about this phenomenon and its effects on evolution remains limited. A major obstacle to the study of polyploidy is the great difficulty in untangling the origins of allopolyploids. Due to the drastic genome change...
Grasses (Poaceae) comprise around 11,800 species and are central for human livelihoods and terrestrial ecosystems. Knowing their relationships and evolutionary history is key to comparative research and crop breeding. Advances in genome-scale sequencing allow for increased breadth and depth of phylogenomic analyses, making it possible to infer a ne...
The rhizomes of Zingiber are highly diverse and have potential in taxonomy, but their fundamental structure has never been properly understood in connection with an understanding of the sympodial growth form of the whole plant. This study is based on a literature review and on observations of fresh materials of 32 Zingiber species mainly from China...
Chimonocalamus is a genus in the Arundinarieae (the tribe of temperate woody bamboos), distributed in the Eastern Himalayas, India, Myanmar, China, Thailand, and Vietnam. Distinguishing characters of the genus include pachymorph rhizomes, rings
of root thorns at lower culm nodes, a branch complement of 3–5 subequal branches, paniculate inflorescen...
Zingiber (Zingiberaceae: Zingibereae) is an economically important but taxonomically difficult genus, with names frequently misapplied. Here, we thoroughly review all names corresponding to the currently recognised 54 species from China including their synonyms, and clarify the status of their types. Lectotypes are designated for 40 names (includin...
The objective of this work is to elucidate the flowering structures of Chinese bamboos applying the synflorescence concept. To keep in line with grasses, the bamboo synflorescence is defined as a whole culm or a whole branch terminating in an inflorescence. For the first time, the repetitive and fundamental unit of bamboo synflorescences is clearly...
Neomicrocalamus and Temochloa are closely related to bamboo genera. However, when considered with newly discovered and morphologically similar material from China and Vietnam, the phylogenetic relationship among these three groups was ambiguous in the analyses based on DNA regions. Here, as a means of investigating the relationships among the three...

Identifying a bamboo taxon from the Asian seasonal tropics is notoriously difficult, if not impossible, especially when the type material is lacking vegetative parts. This is due to the fact that old type material associated with the naming of bamboos often consists of only flowering branches and perhaps just a few leaves, and, as bamboos in the fi...
The identity of Meistera vespertilio is clarified based on a recent collection of flowering material from the type locality in northern Vietnam. We show that this name has to be applied to a yellow‐flowered species with echinate fruits widespread in southern China, northern Laos and Vietnam. This species was misidentified in all previous works as M...
