0.1 mm long, sparse, distributed on the branches, stipules, rachis, abaxial face leaflets and pedicels.
0.1 mm long, straight, sparse, lutescent, distributed on the branches, stipules, petiole, rachis, leaflets, pedicel ovary and fruit.
Senna reniformis can be easily identified by its arboreal habit, leaves with 3-4 pairs of leaflets, subreniform stipules, acuminate-caudate apex, amplexicaul, subcordate-subauriculate base and extrafloral nectaries located between all pairs of leaflets and the pedicels of the flowers.
0.1 mm long, dense, distributed on the branches, stipules, petiole, rachis, and pedicel.
On shoot apex longitudinal section was possible to observe standard type colleters between leaf primordia and stipule, emerge on secretion (fig.
In senescent phase colleters, probably by dehydration of secretion, was possible to define colleters distributed in lines on stipule base (fig.
Scanning electron microscopy revealed the presence of stipular colleters on Morinda citrifolia stipule adaxial surface.
Leaves odd pinnate, petioles 2.5-7 cm long; leaflets (7-) 9-13 paired, obovate to oblanceolate, 0.8-2.5 cm long, inevidently stigulose both surfaces, pale below; stipules semipersistent.
Leaves odd pinnate, petioles 3-9 cm long; leaflets 9-15 paired, obovate or elliptic, 1-2.5 cm long, glabrous above; stipules ca.
Key words: "Cerrado" vegetation, colleter, secretion, stipule, ultrastructure.
For transmission electron microscopy (TEM), colleters from the two outermost stipule pairs, here referred as P4 (the outermost) and P3 (the innermost), were sampled.
In colleters of the innermost stipule pair (P3) the cells have thin walls; dense cytoplasm; large nuclei; numerous mitochondria with well-developed cristae; dictyosomes and smooth endoplasmic reticulum (SER) (Fig.
