FIGURE 1.

Phylogenetic of moss orders based on Liu et al. (2019). Orders in red lack stomata, green have pseudostomata, black have stomata (no records of losses), and blue have documented losses of stomata. Numbers in red represent the minimum times stomata were lost and numbers in parentheses indicate the maximum possible number of losses. The right column indicates the number of families that include taxa without stomata, over the total number of families in the order.
