Summary:Juglans jamaicensis subsp insularis, is an endemism of Pinar del Río, protected by Resolution 330/1999 of the Ministry of Agriculture included in the Red List of Cuban Vascular Flora. It is a species that has been little studied in its physiology and anatomy. The present study aims to characterize the stomas of Juglans jamaicensis subsp. insularis. Epidermal impressions were made with nail polish on both sides of the leaflets. These were observed with a novel optical microscope (NLCD-307 B). The length and width of the stomas were measured with a 40x lens, the density per unit area (cm²) and the stomatic index. The average size of the stomas is 16.5 μm wide and 19.9 μm long. The stomas were considered small, with a high density and a stomatic index of 15.82
