sepe denudatis superne ramulis brevibus ut plurimum fertilibus dense approximatis, foliis patentibus orbi- 
culari-ovatis acutis nervo sub summo apice evanido margine e medio ad apicem minutissime sed dense ser- 
rulato nullibi recurvo cellulis minutis ovoideis ad basin angustis elongatis, perichztialibus e basi ovali 
subulatis thecam ovatam longe superantibus, operculo convexo acuto peristomio interno processibus angustis
