Discussion
Pterygoneurum ovatum is the most common species of the genus and serves to stabilize arid soils (S. Flowers 1973). The setae may reach 3 mm. Faint thickenings reminiscent of a rudimentary peristome can sometimes be found associated with spore sac remnants dug out of the operculum, and the laminal distal cells may by simply papillose abaxially as in P. lamellatum. R. T. Wareham (1939) found the characters of Pterygoneurum ovatum var. incanum Juratzka, the long awns and short setae, inconstant in both American and European material.
