Descr ： Root fibrous, branched ； some of the branches expand- 

 ing into a small disk at the apex. Frond terete, provided with thick 

 and stout stem below, gradually narrowed above, much branched 

 in an alternate or somewhat dichotomous manner, 5-20 cm. hi^h, 

 2-3 mm. thick in the broadest portion. All the segments, except 

 the basal denudated portion, are closely covered with disk-shaped, 

 suborbicular ramuli which prow out one-sided. Ramuli thick, 

 about ^ mm. broad, somewhat spiral in the order of insertion, 

 arnplexicaul at the base ； repand or irregularly crenulate at the 

 margin, with simple or branched setaceous processes on both 

 surfaces ； some of the ramuli expand, in place of assuming the 

 normal form, into short-pedicelled leaf-like phyllodia wnich are 

 oblong or roundish, either smooth or muricated, 3-7 mm. lonp- or 

 more, 2-4 mm. broad. In some forms, almost all ramuli are trans- 

 formed into such phyllodia showing abnormity, as it is shown in 



PI. VI-X. Decemb., 1900.
