 3 cm. long, sessile, subcordate, shining above, dull beneath, very 

 •indistinctly veined, the margins thick and revolute, their bases 

 connected by a stipular sheath; inflorescence terminal, sessile, 

 subcapitate, several-flowered; pedicels very short; calyx about

 {Shafer 4180) with much larger elliptic leaves, 1 1 cm. long or less, 

 but otherwise similar, may, perhaps, be referred to this species.
