“…The inflorescence. The term "inflorescence" we used here is equivalent to "the unit of the inflorescence" (the UIF) [22]. In most grasses, the inflorescence is easily identified as the product of the shoot apical meristem after the transition to flowering, and it is a discrete structure that is terminal on the culm [19].…”

“…The conventional terminology used for analyzing and describing the inflorescence in Poaceae Barnhart (including both grasses and bamboos) is inaccurate [ 19 ]. To reach a better understanding, the concept of synflorescence, introduced by Troll [ 20 ] and expounded by Weberling [ 21 ], has been employed to analyze and describe flowering structures not only in Poaceae (grasses) [ 22 , 23 , 24 , 25 , 26 , 27 ] but also in many other angiosperm families such as Amaranthaceae Juss., Aristolochiaceae Juss., Asteraceae Bercht. & J.

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 identified and termed as the “basic flowering branch”. The basic flowering branch could be considered as the most simplified synflorescence for a bamboo species. Applying the synflorescence concept, the pseudospikelet is interpreted as a sort of basic flowering branch rather than a spikelet. Consequently, the synflorescence development pattern is consistent throughout the whole family. This study also marks the first recognition of both pseudospikelets and true spikelet flowering branches within the same bamboo synflorescence, which is observed in the genera Brachystachyum, Semiarundinaria and Menstruocalamus.

“…Both the type specimen and photos were used for making descriptions. The terms applied to the flowering structure in the analysis mainly follow the synflorescence concept applied to grasses (Cai and Xia 2021 ; Muchut et al 2018 ; Reinheimer and Vegetii 2008 ; Stapleton 1997 ; Tivano et al 2009 ; Vegetti and Müller-Doblies 2004 ). As the feature of branches bearing only a single foliage leaf is uncommon among bamboos, we specially examined and documented branch complements and axes at different stages of flowering to adduce their development from onset of flowering to senescence.…”

Gelidocalamus fengkaiensis (Poaceae: Bambusoideae), a new bamboo species from Guangdong, China, with an analysis of branch development in relation to flowering

Background Bamboos, widely distributed in temperate and tropical Asia, Africa and America, refer to a group of special plants in Poaceae, Bambusoideae. China is rich in bamboo species. However, due to a long flowering cycle, the flowering habit and the flowering structure of many bamboo species are still not well understood. Here, we report a new bamboo species from Guangdong, China and an analysis of its interesting branch development in relation to flowering. Results This species is similar to G. stellatus, the type species, but differs in the characteristics of its lemma and palea, mid-culm branch complement, and culm-sheath ligules. The initial branches at a culm node do not apically develop flowering structures during a flowering episode; instead, these form on what appears to be specialized flowering branches. Conclusions The results of morphological comparison support the recognition of Gelidocalamus fengkaiensis as a new species. And during a flowering episode, two branch types (‘foliage branch’ and ‘flowering branch’) can be distinguished in this species.
