The type of G. exasperata Bail. & Harv., as evidenced by the descip-
tion and by a duplicate in herb. Farlow, is simply the young of the ex-
panded form of G. radula, which grows in deeper water. It sometimes
reaches a length of 100-150 cm. In spite of its size and peculiar red color,
it intergrades with the typical form to such an extent that it cannot be
separated very widely from it. It is a plant of the deeper and more quiet
water.
With cystocarps.
