Comparative anatomical study of the vegetative organs of boldo miúdo, Plectranthus ornatus Codd. and malvariço, Plectranthus amboinicus (Lour.) Spreng. - Lamiaceae

Abstract

An anatomical study of the vegetative organs of Plectranthus ornatus, "boldo miúdo" and Plectranthus amboinicus, " malvariço" was made. Both show non-glandular trichomes on the foliar leaf. In P. ornatus, there are pedunculate glandular trichomes and in P. amboinicus, sessile and pedunculate glandular trichomes. This study is justified by the popular utilization of both species as phytotherapeutic agents.
