摘要

Pyrrosia piloselloides (L.) M.G.Price is an epiphyte preferring twigs of trees and is apt to have the twigs dried. We performed experimental observations of the epiphyte under the conditions of removal of the epiphyte and root anatomical observations of the epiphyte. The removal of the epiphyte progressed growth of the host tree. The root hairs of P. piloselloides were embedded 2 or 3 cell-layers within the cortex of the host branches. The preliminary conclusion is that P. piloselloides is a facultative mild-hemiparasitic epiphyte of fern.
