A posthumous 1889 two-volume collection of lesser-known reviews, essays and biographical sketches by an influential American botanist.

Keeney examines the role of botany in the lives of nineteenth-century 'botanizers,' amateur scientists who collected, identified, and preserved plant specimens as a pastime. Using popular magazines, fiction, and autobiographies of the day, she explores the popular culture of this avocation, which attracted both men and women by the thousands.
