That verdict is sustained by posterity, as Mr Botting Hemsley declares of the former work,—"This grand book must be classed as Lindley's masterpiece.

Both in his books and in his lectures he adopted the natural system of classification and did much to popularise it though, as previously stated, his contemporaries Robert Brown, the Hookers, and G. Bentham were equally powerful adherents of the new system. To quote the picturesque if
