EPIDERMAL CHARACTERS OF BACCHARIS (ASTERACEAE) SPECIES USED IN TRADITIONAL MEDICINE

By FREIRE SUSANA E., URTUBEY ESTRELLA and GIULIANO DANIEL A.

Abstract

<div>A morphological study of 38 species of Baccharis used in traditional medicine</div><div>was carried out to provide some epidermal characters that will contribute to the</div><div>knowledge of the genus. The present study revealed: 1) seven different types of</div><div>trichomes: conical, aseptate fl agellate, fi liform fl agellate, 1-armed, 2-4-armed,</div><div>bulbiferous fl agellate, and glandular biseriate; 2) that 28 of the total of 38 species</div><div>have trichomes in tufts; 3) six different types of stomata: anomocytic, anisocytic,</div><div>cyclocytic, actinocytic, tetracytic, and staurocytic; 4) that some trichome types,</div><div>such as 2-4-armed (B. dracunculifolia) and aseptate fl agellate branched (B. trinervis),</div><div>show a high diagnostic value; 5) that the stomata types can be used to differentiate</div><div>species with similar trichomes type (e.g. B. trimera and B. articulata).</div><div>Illustrations of the studied characters are provided.</div
