its greater size, rigidity, and the number of its scales, from Blech- 
num, with which Brackenridge and Gaudichaud united it on the 
basis of the similarity of its sori. 
Caudex erect, often arborescent, more or less loti wich 
scales, or “‘pulu’’; leaves bipinnatifid to bipinnate, 60-180 cm. 
long in arborescent species, 25-50 cm. in herbaceous forms, usually 
coriaceous; sori linear upon the intercostal arches on either side of, 
and parallel to, the midrib of the pinnule, covered by a coriaceous 
indusium; sporangia short-stalked. 
Type species: Sadleria cyatheoides Kaulf. 
Caudex arborescent, 60-300 cm. in height. 
Leafstalk scaly at base, naked or slightly furfuraceous above;
