The plants referred to this species agree closely with the de- 

 tailed description of Massalongo * as well as with the more meager 



original description of Montagne. In the Taylor Herbarium, 

 there is an Anthoceros from Cape Horn, labeled A. punctatus which 

 belongs here, and, judging from the description, A Jamcsonii Tayl.f 

 is also to be considered a synonym.

Sterile : densely caespitose, brownish -green ; stems erect, sim- 

 ple or with a few lateral branches, sparingly or not at all radicu- 

 lose, the rhizoids, when present, coming from the basal cells of 

 the underleaves; leaves and underleaves similar, transversely in- 

 serted, concave, broadly orbicular-quadrate in general outline, 

 deeply 4-parted (about |), the segments lanceolate, 4-7 cells wide 

 at base, tapering into capillary points (each composed of a single 

 row of 5 or more cells), and bearing on their margins 5-8 pairs 

 of opposite widely divaricate capillary teeth, becoming successively 

 longer toward the base ; upper teeth composed of a single row of 

 cells, lower teeth strongly deflexed, often 2 cells wide in the lower 

 Part and giving off a pair or two of tertiary teeth, the external 

 basal teeth of the outer segments much larger than the others and 

 making the leaves appear 6-parted ; undivided basal part of the 

 'eaves about 4 cells across : leaves subtending branches similar to
