Type.

PARAGUAY • Puerto Bertoni ; Bertoni 3631; lectotype ( designated here): SCP! [ SCPD 00037 ]; remaining syntype: SCP! [ SCPD 00040 ] .

Notes.

The paper in which Bertoni published this species explicitly states that he was working on materials from his own herbarium ( Bertoni 1910). Two specimens with the number Bertoni 3631 are deposited at SCP, and both conform to the protologue. Therefore, the richest of both specimens is selected as lectotype.
