“…Phylogenetic molecular analyses from DNA plastid data supported the monophyly of the genus as well as its sister relationship to Athroostachys Benth. (Jesus‐Costa et al 2018, Vinícius‐Silva et al 2021c). These studies also recovered the clade Merostachys + Athroostachys as sister to Actinocladum McClure ex Soderstr.…”

Based on fieldwork and examination of herbarium specimens, a new Andean species, Merostachys nigricans, from the humid montane forest of Bolivia is described and illustrated. We provide notes about distribution, habitat, ecology, conservation status, phenology, common names, uses, and taxonomic affinities with M. ramosa and M. yungasensis. A distribution map is also included. The presence of an unusually black internal surface of basal internodes distinguishes it from all other species in the genus and gives rise to its name.

“…Arthrostylidiinae is the most diverse subtribe of NWB with 196 described species in 16 genera.

“…In clade III, Aulonemia and Colanthelia are sister genera and those sister to Aulonemiella. Finally, clade IV is formed by one subclade including Athroostachys sister to Merostachys with Actinocladum as sister, and another subclade comprising Alvimia sister to Atractantha and Filgueirasia sister to these two genera (Tyrrell et al 2012, Viana et al 2013a, Jesus-Costa et al 2018a).…”

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.

Merostachys is a Neotropical woody bamboo genus that occurs in the understory and along forest borders. Our taxonomic studies of its species and morphological analyses have allowed us to recognize morphological groups in the genus. Previous molecular analyses, which included relatively few species, supported Merostachys as monophyletic and sister to Actinocladum or Athroostachys. We here provide a phylogenetic estimation for Merostachys based on a broader taxon sampling and seven plastid markers (one coding: ndhF 3′ end; four intergenic spacers: rps16-trnQ, trnC-rpoB, trnD-trnT and trnT-trnL; and two introns: rpl16 and rps16). We aimed to test the monophyly of the genus, to verify its relationship with other genera of Arthrostylidiinae, mainly Athroostachys and Actinocladum, and to test whether the previously identified morphological groups were congruent with the molecular data. The monophyly of the genus was confirmed, as was its sister relationship with Athroostachys, although alternate hypothesis testing could not reject a sister relationship with Actinocladum. Two well-supported clades in Merostachys were recovered, one of which encompasses a polytomy. These clades did not exhibit consistent morphological synapomorphies and were not congruent with the morphological groups; however, floret surface (shiny vs. dull) was correlated with the two clades. The lack of resolution in Merostachys, as exemplified by the polytomy, can be attributed mainly to incomplete lineage sorting, suggesting a recent radiation in this group.
