[Research on microscopic structure of stem and leaf of Lysimachia decurrens]

This paper reported microscopic characters of Lysimachia decurrens. The results showed that secretory canals were scattered in the cortex, pericycle fibres arrayed annularly and pith was large with many secreory canals in the transverse section of the stem. It also showed radiate cuticula grains and round oil cells were found in the upper epidermis cells of leaf, which was bifacial and contained two midrib vascular bundles, one much bigger than the other.
