Abstract

The leaf micro-morphology and quantitative phytochemistry of J. integerrima and J. podagrica were examined to find useful characters for the delimitation of taxa, following standard protocols as described by previous authors. Both species are hypostomatic (paracytic). Trichome (multicellular, non-glandular) are only present on the adaxial surface of J. integerrima and absent in other epidermal surfaces. Phytochemical analysis also showed little differences in the amount of bioactive compounds present in both species. Phenol contents are the highest in the two species: 37.65% in J. integerrima and 36.13% in J. podagrica. The similarities and differences in the foliar epidermal characters and phytochemical content can be used to delimit the two studies species, as taxonomic characters.
