Roper began her
herbarium in 1893, and continued adding to it until 1934. Acting as her associate, Frank Samson became her legal guardian and aided in Roper's research. Frank was known to be an active supporter in all of Roper's work. Roper was also interested in
mosses and
ferns, as well as
Orchidaceae and
Violaceae families. Roper aided James Walter White, another botanist, in compiling a
Flora of Bristol, which was published in 1912. White acknowledged Roper for her "trustworthy and energetic help...for fieldwork...and assistance in literary research and in revision and correction of the press." • Discovered growing in a pond in
