“…Comparatively, within the woody bamboos sampled, intercostal fibers and a midrib with only one vascular bundle (simple midrib) characterize the subtribe Arthrostylidiinae; whereas a stomata apparatus bearing two papillae per subsidiary cell and a midrib with more than one vascular bundle (complex midrib) characterize the subtribe Chusqueinae. The presence of two papillae per subsidiary cell herein supports the assumption of this feature as a synapomorphy for Chusquea (Fisher et al, 2009(Fisher et al, , 2014, although there are not enough studies on micromorphology and anatomy to clarify its value. Currently, the set of features herein observed for Arthrostylidiinae and Chusqueinae is common among all species known within each subtribe and extremely applicable for recognizing these groups (BPG, 2012;Clark et al, 2015).…”

Bambusoideae is a diverse subfamily that includes herbaceous (Olyreae) and woody (Arundinarieae and Bambuseae) bamboos. Species within Bambusae are particularly difficult to identify due to their monocarpic lifecycle and the often long durations between mass flowering events; whereas the herbaceous bamboos are pluricarpic, but often are found with no reproductive structures. The leaf blade anatomy of 16 sympatric species of native Brazilian bamboos (Olyreae and Bambuseae) from the Atlantic Rainforest was studied in order to detect useful features for their identification. All the studied species share the following features: epidermis with a single stratum of cells; adaxial bulliform cells; mesophyll with arm cells, rosette cells, and fusoid cells; and collateral vascular bundles. Herbaceous bamboos share two features: papillae scattered on the abaxial surface and parallel-sided arrays of bulliform cells; whereas woody bamboos share: centrally organized papillae and fan-shaped arrays of bulliform cells. Also within the woody bamboos, intercostal fibers and a midrib with only one vascular bundle (simple midrib) characterize the subtribe Arthrostylidiinae; whereas a midrib with more than one vascular bundle (complex midrib) and a stomatal apparatus with two pappilae per subsidiary cell characterize the subtribe Chusqueinae. There are also diagnostic features for the sampled species, such as: papillae shape, and the outline and structure of the midrib. An identification key for all the studied species is provided based on the anatomical features.Keywords: Arthrostylidiinae, Bambuseae, Chusqueinae, leaf blade, Olyreae.A utilidade da anatomia da lâmina foliar para a identificação e sistemática de espécies de Bambuboideae (Poaceae, Poales) ResumoBambusoideae é uma subfamília que inclui diversas espécies de bambus herbáceos (Olyreae) e lignificados (Arundinarie e Bambuseae). Bambus lignificados geralmente apresentam dificuldades de delimitação e identificação, devido principalmente ao ciclo monocárpico e longa amplitude temporal entre florações; enquanto que bambus herbáceos possuem ciclo pluricárpico, porém frequentemente são encontrados em estágio vegetativo. Foi estudada a anatomia da lâmina foliar de 16 espécies de Bambusoideae (Olyreae e Bambuseae), simpátricas e nativas do Brasil, visando levantar caracteres úteis para sua identificação. Todos os táxons estudados compartilham: epiderme uniestratificada; células buliformes na face adaxial; mesofilo com células invaginantes, células em roseta e células fusoides; e feixes vasculares colaterais. Bambus herbáceos compartilham: papilas dispersas na face abaxial e grupos de células buliformes organizadas paralelamente; enquanto que bambos lignificados compartilham: papilas organizadas em colunas centrais e grupos de células buliformes em forma de leque. Ainda dentre os bambus lignificados, fibras intercostais e nervura central com apenas um feixe vascular (nervura central simples) caracterizam a subtribo Arthrostylidiinae; enquanto que nervura central com mais d...

“…Although tree ferns proliferate in tree-fall gaps in New Zealand lowland forests (Beveridge 1973), their relatively slow growth often allows small, fast-growing trees and shrubs to complete their life cycles during the window of opportunity afforded by these fine-scale disturbances (Ogden et al 1991;Wardle 1991). Since the diversification of Chusquea in South American temperate forests, probably later than the mid-Miocene (Villagrán & Hinojosa 1997;Fisher et al 2014), tree-fall gaps there would have become a less hospitable environment for small trees to survive to maturity, and hence specialize in evolutionary time; this may help to explain the paucity of trees < 10 m tall in the Chilean assemblage ( Figure 5). Additionally, the prevalence of soft leaves among most small trees in the New Zealand assemblage might reflect the historical absence of browsing mammals there.…”

An important tenet of biogeography and comparative ecology is that disjunct assemblages in similar physical environments are functionally more similar to each other than to assemblages from other environments. Temperate rainforests in South America, New Zealand and Australia share certain physiognomic similarities, but we are not aware of any statistical evidence that these disjunct plant assemblages share a distinctive suite of functional traits, or trait combinations. We compiled height, leaf, wood and reproductive traits from the 25 commonest arborescent species at Chilean and New Zealand sites matched for summer rainfall, summer maximum temperatures, and winter minimum temperatures. We then used multivariate tests of trait convergence. Tropical and subtropical assemblages served as out-groups. PERMANOVA showed convergence of trait centroids at the two temperate sites, where trees on average had denser wood and smaller leaves than trees at the (sub)tropical sites. Principal components analyses carried out separately on each assemblage showed that the Chilean and New Zealand assemblages were also the most similar pair in terms of trait relationships, although New Zealand also shared strong similarities with subtropical Argentina. The main axis of variation in both temperate assemblages ranged from small, short-lived understorey trees with soft leaves, to emergents with sclerophyllous leaves and fairly dense wood. However, the New Zealand assemblage was much richer in small trees with soft leaves than its Chilean counterpart; possible historical influences on this difference include conditions favouring radiation of small trees during the late Neogene in New Zealand, competition from Chusquea bamboos in Chile and the historical absence of browsing mammals from New Zealand. Environmental filtering has produced similar values of individual traits in Chile and New Zealand, but only partial convergence of functional trait combinations. As far as we know, this is the first study to statistically test whether disjunct tree assemblages on climatically matched sites are more functionally similar to each other than to assemblages from other environment
