 Leaves entire ; leaves of the stipe remote, isomorphous, sublanceolate-deltoid, 

 acute, straight or subfalcate, to 4 'A mm. long by IVa mm. broad, the 

 base adnate, narrowly 2-auriculate-cordate, the auricles hamate-incurvate, 

 or the inner base deflexo-calcarate and the outer base more bluntly 

 rotundate-auriculate ; leaves of the branches heteromorphous ; axillary leaves 

 2-auriculate (hardly hastate) at the base; lateral leaves horizontal or sub- 

 horizontal on the secondary rachises, ascending on the branchlets; of the 

 principal rachises subremote, obliquely deltoid-lanceolate, subfalcate, unequal- 

 sided, acuminate or acute, the upper side pellucid-margined, rotundate- 

 cuneate in the lower part, provided with a exceedingly minute, erected,
