First records of Melilotus albus Medik. (Fabaceae, Faboideae) in Santa Catarina, southern Brazil

Abstract

Melilotus albus Medik. is a cosmopolite and invasive species, native to the Old World, which in Brazil had its occurrence hitherto recorded only in the states of São Paulo, Paraná and Rio Grande do Sul. This study extends its distribution to Santa Catarina state, southern Brazil, due to the recent discovery of populations in the municipalities of Florianópolis and Xanxerê. These new records are ca. 250 km distant from the nearest records, in Paraná state, also in southern Brazil.

Alysicarpus ovalifolius (Fabaceae, Desmodieae), a new record for the flora of Brazil

“…This is also the second record of a vascular plant new to SC which has been collected in landfills on Santa Catarina Island (the other is Melilotus albus Medik. (Medikus 1787:382) (Fabaceae), whose populations were discovered in 2011; see Hassemer et al 2015). We believe that these species have been introduced to the Island when the landfills were created, most probably by seeds carried on the wheels of the construction vehicles.…”

First records of Landoltia punctata (G.Mey.) Les & D.J.Crawford (Araceae, Lemnoideae) in Santa Catarina, southern Brazil

“…Its conservation status, according to the IUCN criteria (IUCN 2012(IUCN , 2014, is Least Concern (LC). Despite probably being the Brazilian state with its flora best known, there are still considerable gaps in the knowledge of the flora of Santa Catarina (Hassemer et al 2015a(Hassemer et al , 2015b.

First record of Pogoniopsis Rchb. (Orchidaceae: Triphorinae) in Santa Catarina state, southern Brazil

“…Although Santa Catarina has a great history of field surveys and a well-known flora, many new records were made in recent years (Gasper et al 2013a(Gasper et al , 2013b(Gasper et al , 2014Funez and Gasper 2014;Hassemer et al 2015;Funez et al 2016), mostly provided by a large inventory survey performed in Santa Catarina (Vibrans et al 2010). This new record should encourage new field surveys, even in a region where, since the 1940s, botanical collection has been active (Reitz 1965).…”
