BUCCIARELLI, A; CAMBI, Vn  e  VILLAMIL, Cb. Morphoanatomical characters of Araujia hortorum E. Fourn (Asclepiadaceae), a native species of medicinal interest. Phyton (B. Aires) [online]. 2008, vol.77, pp.283-295. ISSN 1851-5657.

Araujia hortorum ("tasi") is a native species of South America, invading crops in several countries. It is used as food and in medicine due to its galactogenic properties. Morphoanatomical and micrographic characters of leaves, stems and roots were studied to determine diagnostic characters that allow its identification in the vegetative state. Stomata and palisade parenchyma indexes, stomata location, the proportion and characteristics of palisade and spongy parenchyma and the scarce quantity of idioblasts, resulted in the most relevant, differential characters.
