This is a remarkable species. The flower stalk stands by 

 itself, and seems to constitute a distinct, leafless plant. On 

 pulling it out of the ground, the root is found to be connected 

 with a leafy stem, which is frequently at some distance from the 

 scape. Leaves at the top of the stem on long stalks, nearly 

 smooth, whitish underneath, ovate, with a short point. Scape 

 smooth, slender, longer than the stem. Flowers purple, in a 

 panicle or raceme, on capillary stalks. — Woods. — August.
