Figure 17

Material. Present in 6% of the shelters with dry vegetation. Shelter-002: LX3338; Shelter-006: LX5573; Shelter-028: LX2941; Shelter-048: LX3325; Shelter-049: LX3334; Shelter-062: LX3254, LX3272; Shelter-097: LX2459.

Remarks. Recognised by very thin cuticle where the paracytic arrangement of subsidiary cells is reflected in the ornamentation of ridges at right angles to the stomatal axis.
