Resumen de Novelties to Compositae Family in Rio Grande do Sul State Flora
Leonardo Paz Deble, Anabela S. Oliveira
Twelve new records to Compositae from Rio Grande do Sul Flora are proposed: Soliva macrosperma Cabrera (Tribe Anthemidae); Baccharis coronata Giuliano, Baccharis flabellata Hook. & Arn., Conyza pampeana (Parodi) Cabrera, Conyza serrana Cabrera, and Podocoma spegazzini Cabrera (Tribe Astereae); Micropsis ostenii Beauveard, Micropsis spathulata (Pers.) Cabrera, and Pseudognaphalium luteo-album (L.) Hilliard & B.L. Burtt (Tribe Gnaphalieae); Trichocline humilis Less. (Tribe Mutisieae); Stenachaenium adenanthum (Sch.-Bip. ex Krasch.) Krasch. (Tribe Plucheae); and Chrysolaena propinqua (Hieron.) H. Rob. var. canescens (Chodat) Dematt. (Tribe Vernonieae). The identity of Hysterionica nidorelloides DC. is defined, being Hysterionica montevidensis Baker its synonym. A superfluous combination under Viguiera santacatarinensis is included as new synonym. Isostigma riedelii (Baker) Chodat is excluded to Rio Grande do Sul Flora, and two new combinations are proposed: Calea paraguayensis (Kuntze) Deble and Vernonanthura nudiflora f. albiflora (Matzenb.) Deble.
