On the flower painting in Bacchus and Ariadne Wethey comments:
Exquisite details are present everywhere in the extraordinary beauty of the green foliage of the trees and of the light, fresh, green grape-leaves that cling to them. Charming flowers accent the foreground: beside the snake-bearer a purple iris and a tall columbine and beneath his feet a spiny plant commonly known as a horsetail (equicetus); just below the baby satyr the glorious white blossom with its crown of fragile stamens and the trailing vine of the Mediterranean caper (capparis spinosa). That Titian observed and painted flowers so delicately has hitherto been largely overlooked. ( Wethey, The Paintings of Titian: Complete Edition, III. p. 36)
Columbine is the English name of the aquilegia vulgaris.
The final comment is true only if Ruskin and his readers are excluded by the term 'largely'.
