NANCY-OVER-THE-GROUND 



Tiarella unifoliata. Saxifrage Family 



Stems: slender, spreading from running rootstocks. Leaves: simple, 

 cordate, acute, obscurely five-to-seven lobed on long fine petioles. 

 Flowers: numerous, in a narrow panicle; calyx cleft to near the base; 

 petals five, filiform; stamens ten. 



The tiny feathery flowers of this plant are found in great 

 quantities in the mountains. Their large heart-shaped 

 leaves appear to carpet the ground about three inches above 

 the soil in the localities where they abound, and their white 

 masses of delicate bloom have earned for them the name of 

 " Foam-Flower." The Latin name Tiarella means " a lit- 

 tle tiara," and refers to the shape of the capsule, while 

 unifoliata refers to the one leaf on the flower-stalk.

 filiform or none. Fruit: seeds hispid. 



This plant is usually found in very dry stony places, 

 among the rocks or on gravelly slopes. It is remarkable for 

 its tall stiff stalks, which are leafless and end in a dense 

 spike of closely-set creamy flowers. The leaves are green
