With cut leafy tops of a xeric-hygric series of mosses, consequently in the conditions independent of ecological factors such as habitats, growthforms, water absorption, etc., the relations between xeromorphism and transpiration were investigated ; special references were taken to the transpiration rate and the water deficit velocity under the laboratory conditions. Under the following conditions in the laboratory, the leafy tops continue to transpire their water for more than 40 minutes to an hour with little reduction in the rate until the hydrability reaches itself to about 50 per cent(in endohydric mosses)or less than 30per cent (in pollacauophytes)
