LUNDELL: THE GENUS PARATHESIS 67 
with no constriction below the calyx. The long petioles, large ovate-oblong erect 
anthers, and finely tomentose ovary distinguish it further. The 8 or 9 ovules are 
partially biseriate, but this may be due to dislocation of ovules from pressure 
applied in drying the specimens.
