Anatomía cavidades lisígenas drusas plantas tóxicas rafidios. Background and aims: Heterophyllaea pustulata (Rubiaceae) grows in northwestern Argentina. It has livestock importance because it produces photosensitization in the cattle that consume it. That is why it is proposed to study the foliar and caulinar morpho-anatomy of the species in order to determine structural characters that facilitate the identification of the plant.M&M: Leaves and stems of young adult plants and seedlings obtained through in vitro cultures were taken and studied by conventional histological techniques. Images obtained with optical and scanning electron microscopy are presented.Results: The results indicate that the studied species have morphological and anatomical characters similar to other species of Rubiaceae, although it presents others that were not previously described, such as the structure of the epidermis with striated cuticle and the anatomy of the stem.Conclusions: It is found that the diagnostic characters that facilitate the identification of the plant are: microdenticulated margin of the lamina, epidermis with striated cuticle in leaves and young stems, simple eglandular trichomes, mesophyll with raphides and druses, in addition to the lysigenous cavities in all the organs of the plant. Introducción y Objetivos: Heterophyllaea pustulata (Rubiaceae) crece en el noroeste argentino. Tiene importancia ganadera debido a que produce fotosensibilización en el ganado que la consume. Es por ello que se plantea estudiar la morfoanatomía foliar y caulinar de la especie con el objeto de determinar caracteres estructurales que faciliten la identificación de la planta. M&M: Se tomaron y estudiaron hojas y tallos de plantas adultas jóvenes y plántulas obtenidas a través de cultivos in vitro, mediante técnicas histológicas convencionales. Se presentan imágenes obtenidas con microscopio óptico y electrónico de barrido.Resultados: Los resultados indican que la especie estudiada comparte caracteres morfológicos y anatómicos con otras especies de Rubiaceae, aunque presenta otras que no fueron descritas anteriormente, tales como la epidermis con cutícula estriada y la anatomia del tallo.Conclusiones: Los caracteres diagnósticos que facilitan la identificación de la especie son: margen microdenticulado de la lámina, epidermis con cutícula estriada en hojas y tallos jóvenes, tricomas simples eglandulares, mesófilo con rafidios y drusas, además de las cavidades lisígenas en todos los órganos de la planta.
