| 1861 Bentley Man. Bot. 744 M. Frémy..has ascertained that it [chlorophyll] is composed of two colouring principles,—one a yellow, which he has termed phylloxanthine; and the other a blue, which he has called *phyllocyanine. 1885 G. L. Goodale Physiol. Bot. (1892) 291 Frémy's later researches have led him to regard the so-called phyllocyanin as really an acid (phyllocyanic). |

| 1955 F. T. Last in Trans. Brit. Mycol. Soc. XXXVIII. 221 It is suggested that, as with roots and the ‘rhizosphere’, leaves have a ‘*phyllosphere’, with a characteristic micro-flora that may contain many species. 1956 J. Ruinen in Nature 4 Feb. 221/2 These observations suggested the existence of a characteristic milieu which is conditioned by the leaf, and may be called, in analogy with the rhizosphere, the ‘phyllosphere’. 1972 J.

| 1858 Mayne Expos. Lex. 954/2 The yellow colouring matter of the leaf of a plant: *phylloxanthin. 1861 Bentley Man. Bot. 745 The experiments of M. Frémy show, that the yellow leaves of autumn contain no phyllocyanine, and hence that their colour is entirely due to the phylloxanthine, either in its original condition or in an altered state. |
