Fig. 3. Examples of variation in stomatal distribution. Light microscopy. (a) Cuticle of Kania eugenioides, showing 'clumping' of stomata with no clear distribution into vein islets or areolae; scale bar: 200 μm. and (b) A close up of the clumped stomata, showing a disorganised distribution in K. eugenioides. (c) Xanthomyrtus montivaga, showing an alternative form of aggregation of stomata into distinct zones, with large non-stomatal areas between zones, with no clear relation to underlying venation; scale bar: 200 μm. (d) A close up of the aggregated stomata. There are no spaces between any of the subsidiary cells of stomata in Xanthomyrtus species, and stomata are approximately half the size (~5 μm).
