THE Natural History Museum is happy in possessing a band of young field botanists who bid fair to bring botanical science, lately overshadowed by the romantic march of the physical sciences, once more into high repute. Of this band, Mr. Taylor is not the least. Meconopsis is one of those select genera dear to horticulturists. But for them it might long have languished in darkness, unhonoured and unsung. British horticulturists have stimulated discovery, cultivation, and study; and Mr. Taylor, with a wealth of material, living and dead, before him, collected primarily in the interests of horticulture, has presented them with a new classification, and brought our knowledge of the genus up to date.
