Abstract
We propose nine new synonyms, and five lectotypifications for South American Miconia (Melastomataceae).
Miconia paulensis is synonymized under M. cinerascens var. cinerascens; M.conferta as a synonym ofM.
inconspicua; Miconia riedelii and M. langsdorffii as a synonym of M. paucidcns; M. camposnovaesii and M.
coralliocarpa as a synonym of/W. pseudonervosa; and/W. hisplda, M. rtgnellii and M. brevipesvnr. longifolia
under M. Irianae. We propose lectotypes for M. conferia. M. hisplda, M. langsdorffii, M. pseudonervosa. and
M. Irianae.
Key words: lectotypes, South America, synonymy, taxonomy.

Introduction
Miconia Ruiz & Pav. has about KXX) species
oceurring through tropical and subtropical America
(Goldenbcrg et ai. 2008). The last complete revision
of the genus is more than 100 years old (Cogniaux
1891), although parts of it have been recently revised,
such as section Hypoxunthus (Rich. ex DC.) Hook.f.
(Goldenberg 2000) and the Antillean species of
section Chaenopleura (Rich. cx DC.) Hook.f. (Judd
2007). Several nomenclatural and taxonomic
arrangements have been published in regional Horas
(Wurdack 1962, 1973,1980; Wurdack tf«/. 1993),
and recent papers (Goldenberg & Martin 2008) but
much work on this group's taxonomy remai ns to be
done. In this paper, we address problems related to
names and species found during work on the
taxonomy of Brazilian Miconia, and during the
preparation of the database for the project List of
Species of the Brazilian Flora (Forzza 2009).
Materials and Methods
The synonymizations and lectotypifications
that are presented here were based on the analyses
of specimens from the herbaria BM, BR, C, ES A, F,
FI,G,GUA,HB,K,L,M,MBM,MO,NY,P,R,RB,
S, SP, UPCB, US, and W (acronyms following
Holnigrenticv/. 1990).
