All of Wells' specimens are recorded as having been collected at "Boxvale". This is now a lost toponym; according to Bruce Maslin it was "somewhere E of York, perhaps near the Cubbine Hills between Cunderdin and Quairading". Wells' specimens are also undated, but are assumed to have been made in the 1870s or before, since they are attributed to her under the maiden name, and she married in 1880.
