The Distribution Of Stomata
Published 1996 · Biology
One of the earliest recorded vascular plants is Cooksonia pertoni and its fossil remains show the presence of stomata (Edwards et al., 1992) (Fig. 2.1). Such fossil records suggest that stomata were relatively large in early plants. In Zosterphyllum myretonianum, stomata up to 120 µm long were recorded (Lele and Walton, 1960–61). These are the largest stomata that have been measured in living or extinct plants.
