acquaintance with this plant in central New York has led to the 
opinion that it is specifically distinct from A. sanguinea. The hypan- 
thium is much broader and more shallow (saucer-shaped), the petals 
are longer, and there are other distinctive characteristics given in 
the table under the next species. Its range, so far as known at 
present, is from central and western New York to Ontario. In 
central New York it inhabits the crests and ledges of shale cliffs 
bordering the ravines and lake shore. These cliffs are usually more 
or less calcareous. The plant is probably a calciphile, but this 
should be verified. New York: Paine’s Creek Ravine, Ledyard,
