Madagascar's fragile ecosystems are vulnerable to invasive plants but accounting for these in a poorly known and undercollected group is challenging due to an insufficient knowledge base. We record three species of grasses (Poaceae) new to Madagascar. Ehrharta stipoides Labill. is a potentially dangerous introduction due to its invasiveness in frequently burned ecosystems. Enteropogon prieurii (Kunth) Clayton is not recorded as invasive but is frequently misidentified due to its similarity to Chloris virgata Sw. The new record of Vulpia myuros (L.) C. C. Gmel. is from a collection made 50 years ago.
