Shoots springing from a high-scandent main shoot, 3 4-pinnate, the 

 stem compressed, pale-ochraceous or ochraceous-green, IVa mm. thick, 

 often slightly grooved when dry; pinnae ascending, remote, the rachis 

 7 10 mm. broad including the lateral leaves; ultimate branchlets 4 5 

 mm. broad. Leaves heteromorphous ; lateral leaves spreading; of the stem 

 remote, oblique-ovate, obtuse, very minutely serrulate on both sides, the 

 upper side gradually ciliolate at the rounded base, the lower side often 

 ciliolate at the narrowly rounded base, the largest leaves 4V mm. long, 

 2Va 2 3 A mm. broad; of the branches nearly similar, approximate to 

 imbricate, often provided with interrupted spurious veinlets, the upper 

 side pellucid-margined, ciliate at the base, the lower side entire except 

 towards the obscurely serrulate apex, ciliate at the base, the ciliae 

 continued upon the rachises; of the principal rachises 5 mm. long by 2
