 prostrate or decumbent, 2-4 dm. long, pilose-tomentose, leafy throughout. Leaves triangular- 

 hastate, 1.5-3 cm. long, terminal lobe narrowly triangular or broader and slightly ovate-

 oblong or oblong-ovate and obtuse, the basal lobes more or less spreading about one-half to 

 nearly as long as the central one ; petioles slender shorter than the blades ; peduncles very 

 slender, usually exceeding the leaves, 1 -flowered; bracts 2-10 mm. below the calyx, hastate 

 and suggesting diminutive leaves ; sepals unequal, the outer much shorter and narrower than 

 the inner, oblong, blunt or truncate and usually mucronate at apex, pubescent ; corolla white 

 or cream-yellow, 25-35 mm. long.
