Notes.

Tanaecium selloi differs from other Tanaecium species by the foliaceous or minute and triangular prophylls of the axillary buds, and fruits without a central ridge but with margins raised. Populations from semi-deciduous and dry areas of Argentina, Southern Brazil, Bolivia, and Paraguay show leaflets that are pubescent abaxially; these features are restricted to those populations (Tab. 1 ).
