Hygromorph

Plants from a humid and shady environment with an ample supply of water possess so called hygromorphic leaves with a single epidermal layer and thin cuticle. Their supportive tissues are reduced. For these plants (hygrophytes) that live in an environment with a high atmospheric humidity, water loss is not a problem. An exampleof such hygromorph species is Ranunculus reptans, the greater creeping spearwort.
