Mr. Niittall never having seen this plant, as it would ap- 

 pear, doubts of its authenticity, on account of the great 

 anomaly in the petals, and is inclined to refer Pursch to 

 villosa. With this species however it has no affinity, being 

 nearest allied to blanda. But I think, whoever has seen 

 even dry specimens, such as I received from my late friend 

 Rev. H. Steinhauer of Bethlehem, found on the Pocono 

 mountain, cannot possibly doubt the species. Mr. Stein- 

 hauer shewed me an elegant drawing he had made from 

 fresh specimens ; the petals exactly as described by Pursch, 

 and shewing some affinity to concolor in their habit. It 

 grows in large tufts, spreading its light green leaves in ev- 

 ery direction. They are of thin consistence and sprinkled 

 with hair on the upper side. My specimens have only ap- 

 etalous flowers. 



This species ought to be closer observed and better de- 

 scribed. The vulgar appellation oi Heal all which Pursch 

 says it goes by, is applied to a great number of very differ- 

 ent plants.
