NO. 1 TAYLOR: PACIFIC MARINE ALGAE 279 



PHYCODRYS Kutzing, 1843 



Plants short stalked, forming broad foHaceous pinnate lobes which are 

 monostromatic except for the veins, which consist of a midrib and opposite 

 macroscopic pinnate lateral veins, the midribs in section not showing rhi- 

 zoids among the large cells of the central portion ; prominent apical cells 

 present, dividing transversely; tetrasporangia formed in scattered sori, 

 in marginal sori, or on small lateral proliferations; spermatangia formed 

 in small scattered patches or in submarginal bands; carpogonia formed in 

 pairs, the gonimoblasts producing spores in chains, the pericarps promi- 

 nent.

 Plate 91, Figs. 1, 2 



Plants to more than 2 dm tall, the lower parts denuded and forming 

 firm irregularly alternately branching stipes, which continue above as the 

 percurrent midribs of the blades; intact blades to 10-17 cm long, broadly 

 lanceolate, about 5 cm in width, with a closely pinnately lobed margin, 

 the lobes from ligulate to broadly lanceolate or rounded triangular, occu- 

 pying about half the width or growing out to secondary blades similar to 

 those which bear them, the lobes in turn marginally crenate or divided to 

 subsidiary lobes; the strong midrib with irregularly alternate lateral veins 

 of different sizes, or these obscure in the younger blades, but reaching to 

 the marginal lobes, the veinlets minute, irregularly branched, generally 

 obscure; tetrasporangial sori in the younger lobes, one on each side be- 

 tween the midrib and the margin, reaching a length of 5-15 mm, near the 

 tip narrow, in the lower part of the sorus nearly a millimeter wide, the 

 thallus thickened and the spores more or less covered by the cortex ; cysto- 

 carps also in the marginal lobes along the veins, generally one, occasionally 

 two, the more distal being younger, in size to 1 mm, or a little more, the 

 pericarp prominent. 



These plants differ from Setchell and Gardner's Phycodrys elegans 

 (1937, p. 92, pi. 24, fig. 47) from I. San Cristobal in several minor re- 

 spects, particularly the width of the blades and their lobes. However, as 

 there is much variation in other species of the genus, the present may 

 prove nothing more than a particularly luxuriant variety of their plant, 

 to which no doubt the relationship is close.
