In addition, GRF shows a vegetation with a very open physiognomy composed almost entirely of
caespitose grasses (Oliveira et al., 2010) that little prevent the direct incidence of solar radiation, contributing to the increase of soil temperature.
Double structures (horizontal and vertical distribution of pasture by
caespitose and prostrate plants) comprise a large part of the biome coverage, which has been shaped by fires and grazing to produce the contemporary physiognomies of these natural grasslands (RAMBO, 2005; SOARES et al., 2005).
Helichrysum species name "caespititium" was derived from the Latin word "
caespitose" which means very much tufted, matted, referring to the cushion-forming growth habit.
Festuca valesiaca is a densely
caespitose perennial and occurs in steppe, alpine meadows and, oak scrubs between 400-2800m.
Three new
caespitose species of Senecio (Asteraceae, Senecioneae) from South Peru.
Annual,
caespitose, much branched at base, tufted, 25-70 cm tall, culms ascending or prostrate, slender, smooth, green, glabrous and rather flattened, mostly covered by sheaths.
Clonal plants with rhizomatous and
caespitose growth forms show different degrees of tolerance and compensatory growth mechanisms to herbivory.
Plant mass formed by entangled filaments,
caespitose, sometimes isolate filaments or in small groups in the mucilage of other cyanobacteria; main filament and branches similar; filaments usually uniseriate, occasionally biseriate, 10.0-11.0 [micro]m wide, irregularly T-branched, Y-false branching present; sheath thin, hyaline; trichomes constricted, sometimes not constricted, 8.0-10.0(-13.0) [micro]m wide; cells cylindrical to rounded, 10.0-12.0(-15.0) urn long; heterocytes intercalary or apical, 9.016.0 [micro]m long, (8.0-)10.0-12.0(-13.0) [micro]m wide.
Comparing life forms we observed that bryophytes and lichen species were often positively associated, associations among chamaephyte species were unusual and
caespitose hemycriptophyte species often participate in positive associations.
A major cause of tiller mortality is the removal of apical meristem, especially of tillers at reproductive stage or in plants with
caespitose growth, where the rapid elongation of internodes causes its elevation to the level of grazing or cutting (DIFANTE et al., 2008; FONSECA et al., 2010).
Plants lack extensive clonal growth by rhizomes and are
caespitose.
Thallus shrubby, erect to subpendulous or rarely
caespitose, rigid, yellow green to almost whitish in some areas which usually belong to branching points or changes in the branches width; profusely and irregularly branched.
