Banlis of tlie St. ijucie Kiver (with T. agrtiria), John Donnell Smitli. 



About llie size of T. (tgrarin and T. Rauei, and not readily distinguished from them ; 

 but they both liave shorter stems, witli the male and female plants growing together, 

 broader more spatulate, more acute, less concave leaves, composed of larger cells, the 

 basilar ones much Ijroader and more pellucid. Furthermore, the furmer is distin- 

 guished by its leaves being but slighth' crisped when dry; and the latter by its granu- 

 lose leaves.

On rocks, Colorado, Br(m(legce {Rem). 



Size (small) and mode of growtii much as in G. ciniferfa; but that has the leaf 

 usually hyaliue-apieulate, or often shortly piliferous, margin more recurved, cells 

 smaller, tliose below niucli smaller and less elongated. Color and general appearance 

 of Zygodon Mongeotii with which it was found growing, but fi'om which it is readily 

 separated by its much shorter obtusish not granulose leav^es, composed of larger cells, 

 those l)el()w more elongated, c\:c. — The species is chiefly characterized by the mutic, 

 subincurved apex of the leaf. Cells in the upi)er i)art of the leaf often broader than 

 long, slightly obscure.

A small species; not larger than the usual forms of //. scrpnin, distinguished bj' its 

 straight stems, distant erec'tisii leaves, ttc.
