 or loosely short-ramose above, decumbent, radicant, multinodulose, partly 

 enclosing with sheaths of leaves, foliate throughout, slender, terete, smooth, 

 attaining about 32 cm. in length, the internodes much shorter than leaves. 

 Leaves alternate, but subfasciculate at the top of stems, sheathing at the 

 base, angustato-linear, entire with smooth edges, but hardly scabrous towards
