Mionandra paraguariensis Chodat (Chodat and Vischer 1917: 165)

Mionandra camareoides var. paraguariensis (Chodat) Nied. ( Niedenzu 1928: 232)

Type.

PARAGUAY - Cordillera • between the municipalities of Caacupé and Tobati; s.d.; Chodat & Vischer 238; holotype: G [G 208718] .

Notes.

After revisiting the original description of Chodat and Vischer (1917) and analysing the type specimen, we disagree with Niedenzu’s (1928) treatment of M. paraguariensis as a variety of M. camareoides . Aside from the difference in leaf indumentum, M. paraguariensis differs from M. camareoides due to its larger flowers, differently shaped petals, stamens with pubescent filaments, and 5 staminodes the same length as the filaments. Thus, we unambiguously recognise it as a distinct species.
