RESUMEN
<p><b>OBJECTIVE</b>To study the characteristic features of Desmodium gyrans in order to provide a basis for rational exploitation and utilization of the herb.</p><p><b>METHOD</b>Samples of the title plant were collected, the microscopic features of cross sections and powders were studied. TLC profiles and UV absorption of the plant extract were examined.</p><p><b>RESULT</b>Calcium oxalate crystals were found in cells of transverse sections. Nonglandular hairs were observed on leaf surfaces. Characteristic peaks in the UV spectrum were identified.</p><p><b>CONCLUSION</b>The distinct characteristic features revealed in this studies can serve as evidence for the identification of D. gyrans.</p>

<p><b>OBJECTIVE</b>In order to prove a basis for rational exploitation and utilization of the herb, the charaeteristic feature for Acanthus iliciflius was studied.</p><p><b>METHOD</b>The botanical and pharmacognostic features of the collected original plant were stadied.</p><p><b>RESULT</b>A. ilicifolius showed obvious pharmacognostic characters. The aerate cells of the root were upgrowth. and four vascular bundles were found in leaf venation.</p><p><b>CONCLUSION</b>The distinct characteristic features revealed in this studies can serve as evidence for the identification of A. ilicifolius.</p>
