entire ; lobules variable in form on the same branch, 

 equal to the upper lobe, or half the size, or absent, 

 subquadrate in form, inflated at the base, upper 

 border inflexed, and notched at the outer angle, so 

 as to form a rather blunt tooth. Stipules not 

 broader than the stem, bifid for half their length, 

 segments narrow, acute, incurved, sinus lunate, 

 sometimes they are obsolete, or replaced by 

 fascicles of very short rootlets. Inflorescence

 leaves, the lobes of which are equal. Female shoots 

 lateral, sessile; involucral leaves larger, lobes ovate- 

 oblong, and lobules lanceolate. In straggling
