with acknowledgements of his great intellectual debts to Warming. Contents The text on growth forms was written anew by Warming for 'Oecology of Plants' New conceptual terms In ‘Plantesamfund’, Warming coined the words hydrophyte, mesophyte, xerophyte and halophyte. Hydrophyte - An aquatic plant; a plant which lives and grows in water. Mesophyte - A name given to plants which grow naturally in conditions of intermediate soil moisture. Xerophyte - A plant that is able to grow where the water supply is small. Xerophytes are plants that are able to control the loss of water from their aërial parts. Xerophytes employ many different tools to control the loss of water, such as; waxy deposits, varnish, or mineral crusts on the epidermis; reduction of air spaces; storage organs; thick-walled epidermis; and cork in woody plants. Some xerophytes are annual plants that grow quickly during the rainy season. Halophyte - A plant which grows in salt-impregnated soils.
