Lectotypus selected here: leaflet illustrated by Ettingshausen (1853, pl. 30, fig. 31) and Meller (2010, pl. 42, fig. 6a, b), GBA 1853/001/0173/8 at the Geologische Bundesanstalt, Vienna (Häring, Lower Oligocene).

Linear basally asymmetrical leaflets of delicate legume foliage, blunt at the apex and with asymmetrical basal venation, 11–19 mm long and 4 mm wide.

D i s c u s s i o n. Previous records of this legume, elsewhere often occurring as compound leaves (e.g. at Kundratice – Kvaček and Walther 1998, Bechlejovice – Kvaček and Walther 2004, as Mimosites haeringianus ) were described from the České středohoří Mountains under the designation Mimosites haeringianus ETTINGSHAUSEN ( Kvaček and Walther 1998, 2004). Because the generic name Mimosites is based on pods ( Bowerbank 1840), a newly introduced fossil genus Parvileguminophyllum for morphologically similar foliage of uncertain affinities (Herendeen and Dilcher 1990) is given preference. The late Eocene flora of Florissant includes very similar leaf impressions known as Prosopis linearifolia (LESQUEREUX) MACGINITIES (1953, p. 126, pl. 46, fig. 1, 5 (non pl. 73, fig. 7); Meyer 2003, p. 105, fig. 95). A more precise comparison has not yet been done.
