Resumen:
Lonchocarpus lilloi (Hassl) Burkart is a tree endemic to Salta andJujuy. It grows between 350-500 m a.s.l. The aim of this work wasto study the leaf anatomy of L. lilloi. We worked with fresh materialcolected from the Botanical Garden of the Miguel LilloFundation and from the Experimental Reserve of Horco Molle. Thematerial was treated with conventional anatomic techniques. Theresults showed a dorsiventral leaf. The adaxial epidermis presentsquadrangular and rectangular cells. The abaxial epidermis, withirregular cells, presents different types of stomata: paracytic,hemiparacytic, anomocytic and amphiparacytic; average size, 27 x20.5 μm; density, 153 stomata x mm2. The trichomes are simplewith an average size of 160 μm and glandular with an average sizeof 64 μm. The principal vascular bundle showed xylem sourroundedby phloem with two sheaths: sclerenchymatic and parenchymatic.Presence of secretory ducts and cubics crystals in lamina and petiole.The diagnostic characters for identification of L. lilloi are: stomatatypes, trichomes, crystals and secretory ducts.
