[This large group of European Plantagos would form an 
interesting intensive study. The late Prof. George Henslow 
said in a paper read at the Linnean Soc. in Nov., 1910, that 
Hoffman proved by experiment that P. alpina and P. 
maritima are identical. The title was t! A theoretical origin 
of Plantago maritima L. and P. alpina L. from P. Coronopus 
L. vars.” 
In 1907 I collected P. alpina at 2745 m. (9,000 ft.) at Mont 
Cenis and on the Col de ITseran (Savoie) and on Mte. Santa 
Maria in the Maritime Alps ; at 2760 m. on the Col de la 
Leisse (Savoie), and at 2530 m. on Aiguille du Goleon. P. 
montana I gathered at 2590 m. (8,500 ft.) on Aiguille du 
Goleon in Dauphine, and at 2440 m. on the Col du Gabbier 
and on the Plateau de Paris, near La Grave, above Grenoble.
