A taxonomic revision of the genus Podagrostis (Griseb.) Scribn. & Merr. is presented, including two new combinations: P. meridensis (Luces) A. M. Molina & Rúgolo and P. novogaliciana (McVaugh) A. M. Molina & Rúgolo. Podagrostis bacillata (Hack.) Sylvester & Soreng constitutes a new report for Colombia. Information regarding synonymy, geographical distribution, habitat, iconography, and vernacular names is provided along with complete illustrations and a list of additional specimens examined. A key for the identification of the species is included as well as a comparative table based on macro- and micromorphological data. The anatomical character of Trichodium net on lemma epidermis, as well as its diagnostic value, is discussed in species of Podagrostis and most related genera (e.g., Agrostis L., Chaetotropis Kunth, and Polypogon Desf., among others).

Flowering in woody bamboos is an intriguing phenomenon. Documenting a flowering event provides valuable information about bamboo life cycles. Chusquea argentina is a species endemic to the Andean Patagonian beech forests of Argentina and Chile. We here report a flowering event of C. argentina in northwestern Argentinean Patagonia. We provide a map of the area indicating flowering sites. Photographs showing details of the flowering event are presented. The epidemiological effects of the flowering of C. argentina are taken into consideration.
