【 摘 要 】

Trichomes are present in all species of Saxifraga L. barring few exceptions. In present study trichomes of 27 species, (among which 14 species not studied earlier), occurring in Indian Western Himalaya were examined and their distribution on plant parts was recorded. Eight types of trichomes were recognized. Among the all plant parts, trichomes are present on the pedicel of maximum species (26 species) worked out. Structural diversity and distribution of trichomes in different sections and subsections show a little systematic relevance. However, a species level differentiation is possible in this genus and an artificial key based on structure and distribution of trichomes is proposed for species identification.
