3. Henriettea glabra (Cogn.) Penneys, Michelangeli, Judd & Almeda (2010: 797) .

Basionym: Henriettella glabra Cogniaux (1888: 538) ≡ Melastoma glabrum Vellozo (1829: 180) , nom. illeg. (Art. 52.1 and 53.2 of the ICN).

Type:— Brazil “ lectotype: Vellozo Fl. flum. icon. 4, tab. 121. 1831 (1827)”, designated by Silva & Baumgratz (2008).

= Henriettea cogniauxiana Penneys, Michelangeli, Judd & Almeda (2010: 797) = Henriettella glazioviana Cogniaux (1888: 539) .

Type:— Brazil “ Habitat in prov. Rio de Janeiro ”, 20 January 1877, A.F.M. Glaziou 8684 (lectotype: BR0000006417802 !, designated here; isolectotypes: BR0000006417819!, BR0000006417826!, BR0000006417864!, BR0000006417888!, C10014580!, G00074221!, K000276122!, P00545621!, P00545622!, P00545623!, R000009785!, RB00603868!, S05-3812!) .

Vellozo (1829: 180) described Melastoma glabrum from the Atlantic Forest in Rio de Janeiro, Brazil, and later Cogniaux (1888) transfered it to Henriettella , as Henriettella glabra . However, Melastoma glabrum Vell. is illegitimate because it is a later homonym of M. glabrum Forster (1786: 34) , described from the Society Islands, French Polynesia.According to art. 58.1 of the Code, Henriettella glabra Cogn. has priority from 1888 and is the basionym of Henriettea glabra .

Cogniaux (1888) described Henriettella glazioviana based on Glaziou 8684, and indicated the herbarium B, BR and C as the accessible collection of the type material. Within these, the specimen BR0000006417802 was selected as lectotype, because it was the only with the information of the locality indicated in the protologue, and also handwritten by Cogniaux.

Penneys et al. (2010) recognized both species, Henriettea glabra (Cogn.) Penneys, Michelangeli, Judd & Almeda and Henriettea cogniauxiana Penneys, Michelangeli, Judd & Almeda (≡ H. glazioviana ), probable they missed the synonymization by Silva & Baumgratz (2008). So here we recognized the name Henriettea cogniauxiana as a synonym for Henriettea glabra .
