“…Greco et al (2015) recorded 164 native woody bamboo taxa for Brazil, among them varieties, subspecies, uncertain species, and synonyms, and Filgueiras & Viana (2017) cited 18 genera and 165 species, several of them endemics and endangered with extinction. Here we record 17 genera and 168 species, 16 of them newly described since the compilation by Greco et al (2015) (Parma et al 2016, Mota et al 2017, Vidal et al 2018, Jesus-Costa et al 2018b, Pianissola et al 2018, Afonso et al 2019, Andrade et al 2019.…”

Background: The Neotropical woody bamboos (NWB) comprise a clade native to the Western Hemisphere. Taxonomically the NWB are classified into three subtribes: Arthrostylidiinae, Chusqueinae, and Guaduinae. These woody bamboos are distributed from northern Mexico and the West Indies to south-central Chile and Argentina and from sea level to over 4,000 m in elevation. The most recent comprehensive treatment of the diversity and classification of NWB was published just over 20 years ago, and knowledge of the NWB has greatly increased in the interim. Questions and / or Hypotheses: How much has our knowledge of Neotropical woody bamboo diversity, distribution and classification changed in the last 20 years? Results: The present work reviews the current state of Neotropical woody bamboo taxonomy and provides 1) new morphological keys (in English and Spanish) to and synoptic descriptions of the NWB genera; 2) an updated comprehensive species list; and 3) a biodiversity analysis by country and habitat type. Neotropical woody bamboo diversity presently totals 446 species in 23 genera. In the 21st century, 103 new species and five genera of NWB have been described. Conclusions: The new species and genera described since 2000 have produced an increase in species richness of 29.5 % and a net increase in generic richness of 26.3 %. This new review will be useful for systematists, ecologists, conservation biologists and others working with woody bamboos in the Neotropics.

Otatea is the second‐largest genus in subtribe Guaduinae, Bambuseae tribe of subfamily Bambusoideae (Poaceae) and has its geographical distribution in Mexico, El Salvador and Colombia. Ten of its 12 species are endemic to Mexico. The species with the most widespread geographical distribution in Mexico is Otatea acuminata. Recent fieldwork in the Mexican state of Durango found a flowering population of Otatea aff. acuminata, which sparked further investigation of the species. Previous molecular and morphological analyses indicated that O. acuminata is a polyphyletic species. Our aim was to delimit the species of the Otatea acuminata species complex using molecular and morphological data in a phylogenetic framework and applying parametric species delimitation methods. To this end we used both chloroplast and nuclear sequence data in combination with morphological characters to conduct phylogenetic and species delimitation analyses. Our phylogenetic and species delimitation results indicate that the former O. acuminata population of Durango is a distinct species. Collected flowering plants allowed us to prepare a complete description of the new species, which we have named O. odam. With the description of this new species, the number of Otatea species endemic to Mexico increases to 11. Otatea odam sp. nov. inhabits the ecotone between tropical dry forest and xerophilous scrub of the Madrean, Madrean Xerophilous and Tropical ecoregions of the Sierra Madre Occidental, suggesting that this species is a drought‐tolerant woody bamboo.

Aulonemiella (Poaceae: Bambusoideae: Bambuseae: Arthrostylidiinae), a new Andean genus from Colombia and Ecuador, is described and illustrated. It is characterized by its delicate scandent, vining habit, filiform to narrowly triangular, reflexed culm leaf blades, short, delicate foliage leaf fimbriae, synflorescences with subtending bracts and prophylls, awnless spikelets in spicate to racemose synflorescences and clavate rachilla internodes. The new species Aulonemiella laegaardii (southern Ecuador) is described, and the new combination A. ecuadorensis (Colombia and northern Ecuador) is made. Aulonemiella laegaardii is smaller overall and more delicate than A. ecuadorensis; it is also distinguished by its filiform, recurved culm leaf blades and paleas shorter than the lemmas. The culm leaf blades of A. ecuadorensis are narrowly triangular and straight, and its paleas are subequal to the lemmas; in addition, the synflorescence axes of A. ecuadorensis are usually apically zigzag at maturity.
