Tafted ,^ about 5 cm. high in my specimen, covered with adpressed 

 pale hirsute hairs. Stem very short, erect, ligneous, leafy. Leaves dense, 

 petioled, flabellately simple-ternate ; leaflets sessile, obovato-spathulate to 

 oblong -spathulate, cuneate towards the base, truncate and coarsely 3- 

 dentate with equal acute or acutish and deltoid or ovato-deltoid teeth at 

 apex, thickly membranaceous, concolorous, the middle one a little larger 

 and 9-16 mm. long; petiole stout-filiform, shorter or more or less longer 

 than the blade ; stipule relatively large, broad, membranaceous, adnato 

 below, the upper free portion subulate -lanceolate to subulate -deltoid, 

 acuminate, entire, longer than the adnate portion in the su[)erior 

 leaves. Peduncle erect, exceeding the leaves, loosely branched; bracts 

 leaf-like and ugually stipulate but smaller, the superior ones much de-
