ResumoObservations on the longevity of Goodyera pubescens evergreen leaves are re ported, as are continuing observations of the ecology of Triphora trianthophora. To my knowledge, no one has ever bothered to find out how long the leaves of Goodyera pubescens (Willd) R. Br. remain ev ergreen in the wild. After years of good intentions, I finally marked two leaves in the summer of 1985, making sure I was tagging the newly emerged leaf of that season. The colony on which I chose to do this experiment was one of the largest and healthiest I have ever found, consisting of approximately one hundred plants, all in prime condition. In this particular station the creeping rhi zomes are partially exposed on the surface of the ground, making it easy to distinguish the separate rosettes and growing tips. One clump grows entirely exposed on the surface of a rock outcropping. After the tiny emerging leaf had made sufficient growth early that summer, I tied a strip of plastic made from a plastic baggie to the base of the leaf. Each year thereafter I checked the two spec imens. In the three succeeding years of 1986, 1987, and 1988,
