Luehea uniflora A.St.-Hil. var. gracilis Schumann (1886: 153) .

Type :— BRAZIL. “In silvis provinciae Rio de Janeiro et S. Paolo ”, October 1833, Riedel 1397 (lectotype, designated here, P! [ P02142949 ] ; isolectotypes BR! [ BR05491377 ]; C! [C10023264]; E! [E00894823]; LE! [ LE00006867 ]; P! [ P02142948 ]; S! [S13-21808]; W! [W1890-0002582]) . [= Luehea candicans var. gracilis (K.Schum.) M.C.S.Cunha]

Schumann (1886) described L. uniflora var. gracilis based on Riedel 1397, and several duplicates are kept in different herbaria. Cunha (1980) indicated this collection from Herbarium M as the ‘holotype’, but this specimen was not found (H. Esser, pers. comm.). Since Schumann (1886) did not specify any herbarium and since we have not found any specimen in Herbarium B where he worked ( Stafleu & Cowan 1976 –1988: 400), we designate Riedel 1397 (P 02142949) as the lectotype of L. uniflora var. gracilis , according to Art. 9.3 of the ICN. It was chosen as the most representative, complete, and best-preserved specimen congruent with the protologue’s description. Cunha (1980) has restored the nomenclatural priority, recombining L. uniflora var. gracilis as L. candicans var. gracilis . We confirm here the application of this name.
