Nothing but a careful stud)'^ of the living plants will settle the still 

 doubtful question as to the identity of these two species,

■ triaristata, Req. .'' J. B. sp. 



triuncialis, L. J. B. sp. ? As I before remarked, I am unable 



to distinguish the species of "this genus ; I believe that I have 

 found the above four forms, and probably the jE. triticoides, Req., 

 and J^. cylindrica. Host, are also to be found ; the genus calls for 

 careful examination.

 many of the described species of this section are merely variable 

 forms of two or three types, Bertoloni unites T. glaucum of Host 

 with T. repens, L.

T. repens ?
