Galaxaura veprecula Kjellman 



Plants bushy, short stalked, the holdfast broad and discoid, height 

 5-8 cm or more, the terete stalk 1-2 cm long; densely branching, some- 

 what flabellate, the basal substipitate and subterete, those above flattened, 

 more or less regularly narrowly dichotomous ; internodes continuous or 

 constricted and proliferous, 0.5-1.2 cm long, 1-2 mm broad, clearly 

 broader at the distal ends, the margins thickened, smooth and nitent, or 

 chalky where covered with spinulose cells; medulla of filaments 7-12 /* 

 diam. ; cortex tristromatic, the inner layer of colorless cells 20-30 [x tall, 

 35-45 IX diam., intermediate layer subglobose or somewhat lobed, cells 

 about as large, or when lobed very much broader, the cells of the outer 

 layer forming a continuous epidermis, angular in surface view, lenticular 

 to hemispherical in section and 10-15 /a tall, 18-20 p. broad ; spinulose cells 

 in scattered patches over the frond surface, and especially the margins, 

 easily rubbed off, the cells columnar to clavate or pyriform, 25-35 /u, tall, 

 to 12-15 ju. diam., at the apex rounded to mucronate; plants monoecious, 

 the cystocarps discharging from ostioles near the margins, the sperma- 

 tangia generally scattered.

 constant width or slightly broader upwardly; proliferations infrequent, 

 encircled by a tuft of assimilatory filaments about 1 mm long; structurally 

 of a medulla and an assimilatory cortex, the medulla of filaments 8-15 /x
