Published in 1981 (Smithson. Contrib. Bot. 47), Oxalis gagneorum (Oxalidaceae) was drawn in 1978 from the type collections of Betsy H. Gagné 1216, collected from Fatu Hiva, Marquesas Islands. Interestingly, the particular type specimens used could be traced by the photocopies of the unmounted pressed plants from which Tangerini made her sketches and final ink drawing. The three pressed plants became at least two isotype collections. One of the specimens is now an isotype housed at Paris, another is a US isotype. The third copy Tangerini could not match although it may be from another herbarium and not digitized. The habit in the illustration appears as one plant although there seems to be use of a second collection in the placement of some of the branches. The drawing was done in pen and ink on the now obsolete Cronaflex drafting film which has developed a slightly yellow tint from age. Tangerini remembers the drawing of the woody stem as an advance in her techniques to show the texture of bark.
