Notes     (Last Modified On 3/27/2009)
general taxon notes:
The main distinctive features of this species are: 1) plants slender, irregularly and densely branched (sometimes loosely); 2) stem leaves gradually narrowed from an ovate base to a long apiculate apex, with margins recurved and obviously plicate; 3) costa rather slender, ending below apex or at 2/3 the leaf length; 4) leaf cells short and small, upper and median cells round-polygonal; basal cells near margins subquadrate, smooth; and 5) capsules erect; peristome double, but endstome segment reduced and cilia rudimentary.
