The sambong (Blumea balsamifera (L.) DC.)
leaf was investigated by applying frozen section and thin section technology,
and observed through optical microscope. The results showed that the sambong
leaf was firstly originated nearby the apical bud at the stem tip. The first
leaf grows fast, that the mitosis happens frequently and the cytoplasm manufacture
rapidly. The cells in the first few leaves have not yet differentiated into the
spongy parenchyma and palisade parenchyma. In the mature leaf, the
spongy parenchyma and palisade parenchyma were fully developed. The epidermal
hairs were firstly developed on the abaxial side of the first leaf.
