Abstract
1. Field studies on Impatient parviflora DC. in shaded situations indicated the need for experimental investigation of the effects on growth of varying single factors of the aerial environment in otherwise constant conditions. 2. The use of cabinets which allow accurate control of the aerial environment for studies in physiology, morphogenesis, pathology and plant selection is discussed. 3. By comparison of the development and assimilatory ability of the leaves of I. parviflora , it is shown that plants may be grown in wholly artificial conditions which are substantially identical with those grown under comparable conditions out of doors.
