Buccal cone short, labrum rounded, with feebly ventral sclerification
brizantha exhibited sclerification
of This layer, which may be a physiological response of the cultivar to stress, being able to prevent or hinder the entry of pathogens, especially because it is the most striking characteristic in samples in a more advanced stage of the DPS.
Anatomical markers of taxonomic importance are the nature and size of macro- and micro-hairs, shape of bulliform cells, arrangement of vascular bundles and amount of sclerification present in the leaves, which may be used for resolving taxonomic problem of problematic genera within tribe Paniceae.
Sclerification around vascular bundles, microhairs and presence of bulliform cells in groups might be an adaptation of this grass to tolerate severe drought and high salt concentration (Table 1; Fig.
The size of epidermis cells, size and shape of outer cortical region, presence of sclerification
in outer cortex and endodermal cell area also showed the significant diversity.
of the ejaculatory sac: UNORDERED 0.
Endophallus funnel shaped, elongated, the degree of sclerification
of the tube decreasing until it ends as a membrane which unites with those of the medial cleft.
The cupule provides protection to the developing nut through its armature, sclerification
, and tannins (Kaul, 1985; Kubitzki, 1993).
phloem and parenchyma) contributes to the estimate of sclerification
, but because it was a small fraction of the sectional area of vascular bundles, its contribution was minor.
The size of epidermis cells size and shape of outer cortical region presence of sclerification
in outer cortex sclerenchyma bundles in cortical region and presence of aerenchyma were quite significantly (Pless than 0.
Cultivar Berehmi showed typical characteristics in the root anatomy with well developed sclerification
in cortical region and highly enlarged phloem.
In her neotropical crickets monograph Desutter (1990) mentions that Neomorphini are restricted to South America and are defined by the following characteristics: 1) absence of stridulatory apparatus; 2) five internal (sometimes six) and five external dorsal spurs on hind tibia; 3) endophallic cavity dissymmetrical, irregularly-shaped; 4) ectophallic invagination sclerified, sclerification
surpassing brim of endophallic cavity, dissymmetrical; 5) rami circular.
