Resumen:
Tillandisa didisticha (E. Morren) Baker belongs to the subfamily Tillandsioideae. It is an epiphyte species found in Salta, Jujuy, Tucuman, Corrientes and Formosa. The aim of this work was to the study the leaf anatomy of T. didisticha. The work was carried out on fresh material collected at random from the botanical garden of the Miguel Lillo Foundation and its surroundings. Conventional anatomical techniques were applied. The leaf is hypostomatic with subepidernal tissue. Both epidermis present square to rectangular cells with sinuous walls. Stomata in abaxial surface whit 4-7 subsidiary cells, average size 36x36 μm and density of 10 stomata/mm2. Scales are typical in both epidermis. Mesophyll with aquifer parenchyma and radial clorenchyma. The main vascular bundle showed xylem surrounded by phloem whit two sheaths: sclerenchymatic and parenchymatic. Presence of raphides, styloid and mucilage secretory ducts. Anatomical characters of T. didisticha are an important contribution to future studies in the taxonomy of this group.
