The work in which this species is described for the 
first time being only with difficulty accessible to most of 
the readers of the periodical, I have considered it tit to 
quote here the description given there. — The species 
has a near relative in the indian Oe. HoJienacJcerii Wittr., 
from which it differs among other things in having the 
dwarf male-plants seated on the very oogonia, and in 
having shorter vegetative cells.

Oe. dioicum, nannandrium; oogoniis plerumque sin¬ 
gulis, globosis (rarius subhexagonis), poro foecundationis 
in parte inferiore oogonii sito; oosporis globosis, oogonia 
non complentibus, exosjDorio ”lineis elevatis spiralibus quat¬ 
tuor” ornato; cellulis suffultoriis eadem forma ac cellulis 
vegetativis ceteris ; filis femineis in setam longam hyalinam 
productis; nannandribus in cellulis suffultoriis sedentibus, 
stipite recto, spermogonio exteriore bi- (vel tri-) cellulari; 
diametro oosporarum c:a 51 q. 
Hab. in Pennsylvania in stagnis prope Philadelphia; 
sec. Prof. H. C. Wood. 
Of the above diagnose the same is true as that which 
I have said of the diagnose of Oe. multisporum Wood. — 
This species is rather unlike the others in the same group, 
partly because of its pore of fecundation being placed in 
the lower part of the oogonium, partly (and principally) 
by the peculiar sculpture of the exosporium. I am some¬ 
what Rubious how to interprete Prof. Wood’s figure and 
description of this sculpture. I have therefore quoted his 
own words in the description of it given above.
