Elionurus muticus is a species of the Poacea family, popularly known as ‘Capim limão’ (lemon grass). The species has aroused great economic interest, due to the production of essential oil, with predominant citric odor, coming from the aerial part. In oil, citral is the compound that arouses greater interest, since it is widely used in the perfumery, food and cosmetic industries. The genus Elionurus presents a complex taxonomy, with great diversity and still little clarified, besides presenting taxonomic difficulty related to synonyms. In the case of E. muticus there is not enough information in the literature that adequately characterizes the species, presenting divergences for both the genus Elionurus and the E. muticus species. Due to the productive potential and the need for knowledge, the present work had the objective of performing the botanical evaluation and analyzing the development of the inflorescence of the species. Inflorescences were collected to analyze the botanical structures and flowering stages. From the results, it was possible to visualize the presence of pálea in the spikelets, a structure that is not reported for the genus. In addition, the flowering duration is approximately 30 days, occurring in the months of January and February. There are few studies that address the flowering of E. muticus, this information is of great importance for the knowledge of the species and the creation of strategies related to the management, as well as serving as information for the possible genetic improvement of the species.
