Each species has a brief character attached, and to each genus botanical and practical observations, from the pen of Sir William Hooker, are prefixed. The work is enriched with a prefatory memoir by Mr. Lyons, full of sound judgment and experience, on the most approved method of growing Orchids."—Literary Gazette.
