opposite, in two ranks, not decussate, equally pinnate, with two 
pairs of elliptic, coriaceous, glabrous leaflets thickened at their 
insertion; during winter most of them fall away with exception 
of the terminal pair, which are persistent, and very few pairs 
are produced on each year’s growth. 
Petiole semiterete, somewhat dilated and thickened at the base, 
distinctly grooved above, articulate with the stem. 
Stipules intrapetiolar, connate into a rounded piece on each 
side of the stem on which they are inserted, covering the space
