3. Phyllanthus hypoleucus Müller Argoviensis (1863: 40) .

Lectotype (designated here):— BRAZIL. In Brasiliae prov. Bahiensi , F. Sellow 583 ( F0057027 !, F0BN005030! [photo at B]) . Remaining syntype: BRAZIL. In Brasiliae prov. Bahiensi , F. Sellow 1006 ( B, probably destroyed) .

Müller Argoviensis (1863) described Phyllanthus hypoleucus based on Sellow 583 and Sellow 1006 from Bahia State and deposited in “ hb. Berol. ”. The specimens deposited in B were most likely destroyed. Webster (2002) indicated the original material used to describe P. lacteus (1866: 402) (currently a synonym of P. hypoleucus ) as the holotype of P. hypoleucus . That material was collected by Sellow s.n. from “ Bahia: prope Nazaré” and can be found at G and K. We found a fragment of the original material, Sellow 583, identified by Müller in herbarium F. That fragment may have been removed from the type that was deposited in herbarium B as it contains a label with the inscriptions of the latter institution. Therefore, in order to clarify the identity of the type of P. hypoleucus , we decided to reject the typification proposed by Webster (2002) and to designate the fragment of Sellow 583 deposited in F (F0057027!; Fig. 4 ) as a lectotype.
