(ecology)
Any perennial plant whose winter buds are within 10 inches (25 centimeters) of the soil surface.

Chamaephyte

 

a life form of plants whose renewal buds are found a short distance (20–30 cm) above the ground and are usually protected in winter by the snow cover. Chamaephytes include shrublets (whortleberry, heath), subshrublets (thyme, many species of wormwood), certain perennial herbs (Lamium), and mosses. Chamaephytes prevail in tundras, high mountains, deserts, and certain Mediterranean types of vegetation. The term “chamaephyte” was proposed by the Danish botanist K. Raunkiaer.

As illustrated in Figure 1, the floral community in Tabuk region was dominated by therophytes and chamaephytes.
Although crystalline caatingas have shallow soils, presumably retaining edaphic water for a short time after the rainfall has ended, the fact that they have nutrient rich soils should facilitate rapid nutrient uptake and regrowth of therophytes and the aerial parts of geophytes, chamaephytes and hemicryptophytes once the rainy season returns.
Chi-Square tests indicated significant differences in the percentages of chamaephytes, therophytes and phanerophytes species between the caatinga and the cerrado, and between the caatinga and the cerrado-caatinga transition areas.
Chamaephytes also include some lower shrubs, but they have aerial buds that are much closer to the soil.
Despite the shallow soils, a large prpoportion of the CR vascular floras are represented by geophytes, chamaephytes, hemicryptophytes and nanophanerophytes with well developed underground systems such as lignotubers, or other Specialised storage and bud-bearing structures (Conceicao and Pirani, 2005; Alves and Kolbek, 2010a).
6 %) are woody plants (mainly shrubs), with 55 phanerophytes, 11 chamaephytes, and 24 trees.
The dominant species are chamaephytes belonging to the family Asteraceae such as ankerkaroo (Pentzia incana) and other species of the same genus, pteronias (Pteronia), etc.
The functional groups of chamaephytes and therophytes II were associated with wetter sites, while the groups of non-tussock hemicriptophytes I, tussock hemicriptophytes (FG4), and geophytes (FG5) were associated to the drier ones.
They are herbs, terrestrial, epiphytic (erect or pendent), or, rarely, saxicolous shrubs and subshrubs 1-2 m tall, lianas, cushion plants, prostrate mat-forming chamaephytes, and trees to 20 m tall (for trees see Judd, 1984; Sorensen, 1995).
