Stem terete in lower portion, angular above, where 

 affected by decurrent leaf-stalks, glabrous. First internode

 others extending from the base almost to the margin, the

 vertically flattened petioles from 2 to 3*3 cm. long, 2 cm. 

 broad, and having up to eleven pairs of leaflets; or they 

 may be phyllodes, usually triplinerved, the third or upper
