CARPOPHYTA. 153 
316. The sexual organs consist of carpogones and anther- 
ids. The latter are situated singly or in groups on the 
ends of branches (A and B, a, a, Fig. 77). The anthero- 
zoids are small round bodies which are destitute of cilia 
Fic. 77.—Sexual reproduction of Red Seaweeds 4 (Lejolisia): a, antherid; 
2, antherozoids; b, carpogone, with antherozoids attached to the trichogyne; s, 
section of ripe spore-fruit, from which a apor (fruit-spore) is escaping. B

(Nemalion): a, antherid, and antherozoids; 
carpogone. D and E, develop-

(A, x, Fig. 77), and are carried about by currents of water, 
and in this way brought to the carpogones. 
317. The carpogones are somewhat variable as to their 
complexity, being much more simple in the lower orders 
than in the higher. In some cases (Nemalion) the carpo- 
gone (B, 6, Fig. 77) is thickened below, and elongated 
above into the trichogyne, which differs from that in Co- 
leochete in not being open at the top.
