eco-organ  

A term used in some modern attempts to devise a system for describing vegetation types on the basis of life-form rather than species composition. An eco-organ is a characteristic morphological ...
hemicryptophyte

hemicryptophyte  

A plant life form in Raunkiaer's system of classification (see physiognomy). Hemicryptophytes are typically herbaceous perennials, such as grasses, which produce perennating buds at the soil surface, ...
cryptophyte

cryptophyte  

One of Raunkiaer's lifeform categories, being a plant in which the perennating bud lies below the ground or water surface. The groups geophytes, helophytes, and hydrophytes are distinguished by the ...
therophyte

therophyte  

A plant life form in Raunkiaer's system of classification (see physiognomy). Therophytes are annual plants that complete their life cycle in a short period when conditions are favourable and survive ...
chamaephyte

chamaephyte  

A plant life form in Raunkiaer's system of classification (see physiognomy). Chamaephytes are essentially low-growing shrubs, in which the overwintering buds are borne above ground but near the ...
phanerophyte

phanerophyte  

A plant life form in Raunkiaer's system of classification (see physiognomy). Phanerophytes are large shrubs and trees in which the overwintering (perennating) buds are located high above the ground. ...
life-form

life-form  

The structure, form, habits, and life history of an organism. In plants, especially, characteristic life-forms, in particular morphological features, are associated with different environments. This ...
geophyte

geophyte  

A plant life form in Raunkiaer's system of classification (see physiognomy). Geophytes are herbaceous plants in which the perennating buds are below ground, giving rise to corms, bulbs, or rhizomes.

Phanerophytes are large shrubs and trees in which the overwintering (perennating) buds are located high above the ground. The buds are thus at risk of exposure to drought stress or frost, and such plants occur mainly in regions where frost and drought are uncommon, such as the...
