Chromosome counts are reported for 81 collections of tropical grasses from Suriname, Brazil and the Dominican Republic, these representing 29 genera and 65 species. The records for Bulbulus, Guadua, Homolepis and Piresia are the first for these genera, as are the counts for the 36 following species: Arundinella confinis, Axonopus marginaius, Axonopus sp. nov., Bulbulus nervatus, Digitaria fuscescens, D. neesiana, Echinolaena inflexa, Elyonurus adustus, Eragrostis glomerata, E. maypurensis, E. polytricha, Guadua capitata, Homolepis isocalycia, Ichnanthus nemoralis, I. pollens, I. panicoides, I. proeurrens, I. reclivis, Lasiacis ligulata, Manisuris loricata, Mesosetum loliiforme, Olyra cordifolia, O. micrantha, O. obliquifolia, O. taquara, Panicum echinulatum, P. trachystachyum, P. versicolor, Paspalum dispar, P. erianthum, P. melanospermum, P. peclinatum, P. rupestre, Piresia goeldii, Sacciolepis pungens and Sporobolus cubensis. The counts of 2 n = 80 for Paspalum secans and 2 n = 20 for Axonopus affinis differ from the single previous record for each of these species.
