Most species showed a xeromorphic
foliar strategy, as a consequence of prevailing dry conditions.
This region is a peculiar enclave, climatically and floristically distinct from most of southeastern Brazil, having a Caatinga-like dry climate and xeromorphic
vegetation (Ururahy et al.
Johnson and Briggs (1975) considered that the leaves of these typically shrubby taxa show a range of derived, xeromorphic
features including revolute margins, tereteness, reduced "quasi-parallel" venation, thick cuticles, sunken stomata and the presence of sclerotic hypodermes.
There are some decomposing fungi like genera Aureobasidium, Candida, Rhodoturula, Sporobolomyces which are hydromorphic and there are some xeromorphic
genera like Mortiella and Trichoderma while different species of Aspergillus and penicillium has been detected in both soil and water environment .
Torus-bearing pit membranes represent a xeromorphic
adaptation that is advantageous during times of water stress.
Basic structure and composition of both types is dominated by xeromorphic
, drought-deciduous, often thorny, pinnate-leaved, multitrunked trees or shrubs 2-10 m in height, with a strong component of succulents and thorny plants, many of them shared with arbosuffrutescent desert and crassicaulescent desert.
However, recent morphological and anatomical investigations have revealed that blackbrush leaves do not possess typical internal xerophytic leaf design (Gibson 1996, Rundel and Gibson 1996) despite their xeromorphic
This "Restinga" vegetation, formed under strong insolation associated with the wind, in well-drained soil, is directly exposed to the sea water and therefore has a characteristically low load and a xeromorphic
aspect (figure 1).
Scrub within the Savannas Preserve displays the general characteristics described by Myers as "a xeromorphic
shrub community dominated by a layer of evergreen, or nearly evergreen oaks (Quercus geminata, Q.
Also, the thick alethopterid cuticle, inrolled (compression) margin, and hair are xeromorphic
characters long recognized in some alethopterids (summary: Mickle and Rothwell 1982; Zodrow and Cleal 1998).
In Caryophyllales, Frankeniaceae have xeromorphic
This species was uncommon to fairly common in more xeromorphic
woodland with dense understory and forest patches bordering savanna at Monte Tabor and Oventeni, where we obtained photographs and audio recordings.
