 the stem oblong, + 3 mm. long, the apex blunt or rounded, the base 

 obliquely 2-auricu late-cordate, the inner auricle relatively narrow, rounded, 

 the outer auricle proportionally large, much produced, conspicuously 

 hamate-incurvate ; of the branchlets smaller, imbricate, the apex acute or 

 shortly acuminate, the inner side nearly straight, narrowed at the base, 

 the outer side rounded, slightly rounded or subauriculate at the base. 

 Spikes square, terminal on the branchlets, solitary or 2-nate, to 2'/j cm.
