Her last major work was on nightshade (Solanum) plants and appeared in 1909. This material came from the Samoa trip of Karl Rechinger and Lily Rechinger-Favarger.[3] Rechinger's work of Botanical and Zoological Results, submitted to the Academy of Sciences in July 1909, was reprinted in 1910, including Witasek's contributions. The work was published in the same year.[4]
