【 摘 要 】

Micromorphological and ultrastructural analyses of the leaf trichomes ofSalvia fruticosa Mill. were performed by light and electron microscopy. Theleaves bear numerous non-glandular unbranched trichomes, and peltate,capitate and digitiform glandular trichomes. Very elongated flagelliformnon-glandular trichomes densely covered the leaf surfaces, with especiallyabundance on the leaf margins. Peltate trichomes consist of a basal epidermalcell, a very short stalk cell and a large round head of eight secretory cellsarranged in a circle. Capitate trichomes can be divided into two main types,short-stalked and long-stalked, and further into five subtypes according tothe number of stalk cells, morphology and number of glandular head cells.Digitiform trichomes consist of one basal cell, one or two stalk cells andone apical secretory cell, which are of similar diameter and approximatelyequal length.
