the ultimate segments to 15-58 cm long; peripheral vesicles short clavate, 

 the ends broad and low-arched, the greatest diameter of 380-510 [x near 

 the end; the end wall smooth, 19-32 /x thick, with a zone of numerous 

 hair scars just below the widest part; gametangia attached well below the 

 hair zone, one or perhaps to three on a single vesicle, short fusiform, 

 widest near the base, with a blunt tip and thickened end wall, the diameter 

 96-128 /x, length 220-288 fi.

This plant was available in some quantity, but mostly broken. A com- 

 plete specimen with tips was 41 cm tall after drying; its longest branch 

 above the upper fork was 35 cm, but in a specimen collected by Schmitt 

 with 8 major tips one terminal segment was 58 cm long and quite possibly 

 had been broken off at the end. The above description based on the present 

 material differs a little from the original, but certainly represents plants 

 of the same species, and adds the characters of the fertile utricles.

Godium fernandezianum Setchell 



Plants veiy dark green, to 15 cm tall from a small holdfast, with a 

 very short basal stalk or without evident stalk, branching 1-3 times, the 

 branches 3-7 mm diam., at the forks cuneate flattened, to 2.5 cm across, 

 but otherwise cylindrical; peripheral utricles large, subcylindrical, gen- 

 erally 360-500 IX diam., not uncommonly 740-1050 /x and sometimes more, 

 2-3 diameters long, the ends rounded to rounded conical, the end mem- 

 brane smooth, 6-35 IX thick, generally about 20 /x, on the smaller utricles 

 and 10 /i, on the larger ones, with hair scars not frequent or conspicuous; 

 gametangia elongate ovoid to rounded conical, 222-320 ju, long, 75-90 ^ 

 diam., 1-3 attached about the middle of each fertile utricle.

This record gives a notable range to this species, otherwise known 

 only from the Is. Juan Fernandez. The plants were young and small ; the 

 writer has material from Juan Fernandez collected by the Hassler Expe- 

 dition and determined by Setchell, where the plant size must have been
