 rectangular, the middle linear of variable length; perichaetial leaves erect-

482. Brachythecium curtum Lindb. From H. Starkei differs in its

 ly denticulate all around, crowded, not decurrent nor auricled; cells pale, 

 nearly all narrow, only lowest one or two basal rows dilated, alar not larger 

 than inner;costa prolonged above middle, vanishing below acumen: capsule 

 small, round-oval, oblique; teeth dark-orange; segments shorter than very 

 high basal membrane, cilia not appendiculate; lid conic, short pointed; 

 seta minutely verrucose, about 1 cm. long: monoicous. Mac. Cat. 195.

 rent; perichaetial leaves long, filiform-acuminate, arcuate-squarrose: capsule 

 curved, oblong-cylindric; lid sub-obtuse when moist; pedicel faintly rough;
