112 Rhodora [JUNE 
New Hampshire. A study of the plant made at the Gray Herbarium 
not long after its collection seemed to indicate its identity with 7’. cera- 
tophorum (Ledeb.) DC., but since the specimen was barely in flower it 
seemed desirable to wait until fruit might be obtained. In spite of 
several searches made since that time no more plants have been dis- 
covered, but recently a second and more careful comparison of the 
same specimen has been made, with the kind help of Professor Fernald, 
and there seems no room for doubt that the former identification was 
correct. Taraxacum ceratophorum is represented in the Gray Herba- 
rium by specimens from similar situations in the Shickshock Mountains 
and from the cliffs at Bic, Quebec, as well as from further west. The 
station at Bic, which is about 250 miles distant, is the nearest yet 
known to that on Mt. Adams. It is to be hoped that other gullies on 
the Presidential Range may reveal the same species, which forms an 
interesting addition to the slowly increasing alpine flora of the White 
Mountains. The specimen here discussed has been deposited in the 
herbarium of the New England Botanical Club.— ARTHUR STANLEY
