PATAGONIAN EXPEDITIONS I BOTANY. 



dium urvilleanum, this sac is described by Mitten 1 as "attached to the 

 lower part of the stem by its side" ; in the closely related (if not identical) 

 M. brecknockiense (Massal.) Besch. and Massal., its author 2 says: " peri- 

 chaetia ad ramorum basim et in ramulo brevissimo sublaterali radicante 

 posita"; in the species described above, on the contrary, the sac is clearly 

 terminal on ascending stems or elongated branches, showing that the 

 plant is a Tylimanthus. The sac moreover has the same structure as that 

 ascribed to this genus its wall is closely adherent to the calyptra and it 

 bears a cluster of unfertilized archegonia at its mouth. At my request 

 Professor Nathorst has kindly sent me some of the original specimens of 

 Gymnanthe anderssonii as determined by Angstrom. So far as can be de- 

 cided from sterile plants, these belong to the same species as Mr. Hatch- 

 er's specimens, although in some of them the leaves are a little more 

 toothed.
