Within the herbaceous bamboos sampled, the midrib outline and amphistomatic
leaves may distinguish Parodiolyra Soderstr.
Leaves are amphistomatic
and possess anomocytic stomata with perpendicular (Figure 1F) or parallel (Figure 2G) cuticular striations surrounding the stoma.
The majority of the taxa are amphistomatic
except Senecio chrysanthmoides and two species of Cremanthodium where they are present on abaxial surface only.
Cotyledons (Figure 4A and C) of the three species consist of uniseriate, glabrous and amphistomatic
epidermis, and dorsiventral leaf with a layer of palisade parenchyma and bi- or multiseriate spongy parenchyma.
The leaflets inboth species are amphistomatic
, although the stomata on the abaxial surface of the leaflet are more abundant (Figs.
montana are distinctive in being amphistomatic
and in having variable concentrations of often conical papillae on their surfaces.
fluminensis has leaves that are amphistomatic
, and the other two species have leaves that are hypostomatic.
Leaves were amphistomatic
and amphitrichomic with higher frequency of both stomata and trichomes on the abaxial surface.
Gibson (1996) state that more than 90% of non-succulent woody species in warm, inland deserts have amphistomatic
The leaves are generally amphistomatic
, with more stomata present on the abaxial surface.
leaves occur in two willows, Salix turnorii and S.
The leaves of the amphibious species Cyperus odoratus, Oxycaryum cubense (Figure 4) and Pycreus macrostachyos and of the emergent species Habenaria repens (Figures 5) are hypostomatic, whereas those of Echinodorus grandiforus and Eichhornia paniculata (Figure 6) are amphistomatic
