Flexious

while the fibrous structure of the frog assumes a tubular form, becomes finer, softer, and has a flexious arrangement; is tough, elastic, and flexible, being admirably adapted for protecting delicate parts and breaking concussion.

O. davisense can be distinguished because the flexious ribs are about half as numerous per whorl as those of O. puzosiforme.

Flexious rods were not observed in cell preparation from healthy sorghum plants

In addition flexious microtubules were seen between the membrane saccule and the fibrous deposits (Fig. 5b).
