The differences between-alpine and non-alpine plants of the same or closely related species have been summed up as follows: ^ "The alpine individuals have shorter stems, smaller leaves, more strongly developed roots, equally large or somewhat larger and usually somewhat more deeply colored flowers, and their whole structure is drought-loving (xerophilous)." 1 By A.
