Shoots decumbent, trailing, repeatedly forked or subpinnate, probably 

 caespitose, the secondary shoots pinnate, the stem slender, stramineous, 

 to '/a Mn^- thick, irregularly grooved when dry, S'/^ — 4 mm. broad 

 including the lateral leaves; pinnae distant, oblique, simple or forked, or 

 subpinnate; ultimate • branchlets short, to about 6 mm. long, I'/j— S'/^ 

 mm. broad. Leaves heteromorphous ; leaves of the lower plane spreading 

 and spaced on both stem and branches; of the stem broadly ovate, 

 I'/i — 2'/4 nam. long, to I'/-, mm. broad, very unequal-sided, blunt or 

 bluntish, minutely but rather copiously papillose-puberulous above, 

 the upper edge obsoletely serrulate towards the apex, serrulate at the 

 middle, gradually cihate towards the base, the lower edge subentire or 

 obsoletely serrulate, and often sparingly ciliate-serrulate at the base, the 

 upper base much dilated, broadly rotundate-cordate, the lower base 

 narrowly rotundate-cordate, ■ the costa wanting in the upper '/g ; of the 

 ultimate branchlets to 1 % mm. long, less unequal-sided, more remotely 

 serrulate and ciliate, the upper base rotundate-cuneate, the lower base 

 rounded; leaves of the upper plane erect, , spaced on the stem, close on 

 the ultimate branchlets; of the stem ovate, long-acuminate to cuspidate, 

 nearly keeled, to about 1 mm. long, the outer side minutely serrulate, 

 produced and rotundate-subcordate at the base, the inner side ciliate, 

 rounded or rotundate-cuneate at the base; of the ultimate branchlets 

 smaller. Spikes solitary or double, about 4—6 mm. long, 2-2V2 mm-
