Epidermal morphology, the structure and development of stomata in 13 species of Boraginaceae are described. The epidermal cells are straight‐walled on the upper surface and sinuous on the lower in the majority of the investigated species. The leaves are hypostomatic with either anomocytic or anisocytic stomata distributed on the lower surface. The anomocytic stomata follow agenous ontogenetic pathway while the anisocytic stomata are hemimesogenously derived. Laterally contiguous stomata in Cordia platythyrsa are recorded for the first time.
