Kallymenia multiloba n. sp.^^*' 

 Plate 70 



Plants to 20 cm tall, 30 cm broad, deep rose red, darker toward the 

 base; firmly gelatinous in texture; from a small holdfast a short com- 

 pressed stalk a few millimeters in length expands into the blade which is 

 cleft to near the base into cuneate segments narrow below, transversely- 

 expanded above into the 2-4 divisions, which are deeply subdigitately 

 lobed, the segments 1-5 cm broad at the base, tapering to blunt or sub- 

 acute apices; thickness 250-300 fx; structurally showing a moderately 

 lacunose filamentous medulla about 125/1 thick of mixed thin- and thick- 

 walled filaments, the former distinctly anastomosing; the inner cortex of 

 three layers of moderately firm-walled cells, smaller and more compact 

 outwardly, and one assimilatory layer of small rounded cells 4-9 fx diam. 

 with rather thick: lateral walls ; spermatangia spherical, 2-4 /x diam., one 

 or two developed on each surface cell of large areas of the blade ; cysto- 

 carps of 0.5-1.0 mm diam., projecting, the spore mass surrounded by the 

 filamentous medulla, of small groups of small carpospores separated by 

 sterile tissue.

Kallymenia latiloba n. sp.^^^ 

 Plate 71, Fig. 1 



Plants to 15 cm tall, 25 cm broad, gelatinous, rose red, without sig- 

 nificant stalk, from a small holdfast expanding to a flat blade, cleft nearly 

 to the base into 2-3 primary segments, the segments expanding abruptly, 

 deeply divided into broad blunt or emarginate ligulate to triangular seg- 

 ments; thickness about 200-300 p. (soaked up) ; structurally of a wide 

 medullary area containing a very sparse, loose arachnoid tissue scantily
