Summary The overall silica content in 10 rattan species was analyzed. Its distribution within the stem of Calamus merrillii Becc. was also tested. Anatomical observations were performed to explain the silica content variation. Ash and silica content varied among species. Regardless of diameter class, silica accounts for 44% to 48% of the overall ash content of the stem. Silica in the medium and small diameter stem was twice as much as in the large diameter stem. Within Calamus merrillii Becc., silica was abundant in the epidermal layer. It was responsible for 74% to 85% of the total silica content of the stem, which explains the variation in silica content between diameter classes. The proportion of epidermal layer contained in the sample deviated among the species causing a variation in silica content. Epidermal silica did not vary along the length of the stem while silica in the stem itself varied significantly from base to top. Differences in silica body frequency per vascular bundle caused such deviation.
