本研究的目的是促进杂草和路边植被的RS 142的路边，从第23至第33公里的指标，在Nao-Me-Toque镇（52° 50 'W e 28°30'S），在南里奥格兰德南里奥格兰德州的Planalto Medio地区的植物区系和植物社会学知识。经鉴定，共有蕨类植物57科181属244种，并对这些植物的俗名、地理来源和用途进行了考证。种类最丰富的科是菊科（61种）、禾本科（33种）、豆科（16种）和伞形科（10种）。在植物社会学研究中，我们在沿着建立了38个一平方米的样方。重要性较高的物种有百喜草、狗牙根、百喜草、- 禾本科（Poaceae）和凹叶扁叶蜂（Facelis retusa（Lam.）Sch.Bip. - 菊科本地种占优势，占81.1%。所研究的植物群包括草地和杂草两种。
This study aims to contribute to the floristic and phytosociological knowledge of ruderal and roadside vegetation on the roadsides of the RS 142, from the 23rd to the 33rd kilometer indicators, in the Nao-Me-Toque town (52°50’W e 28°30’S), on the Planalto Medio region of Rio Grande do Sul State. Two hundred forty-four species, 181 genus, and 57 families, belonging to Pteridophyta and Magnoliophyta, were found. The popular name, geographic origin, and use of the species were verified. The richest families in species were Asteraceae (61 species), Poaceae (33), Fabaceae (16) and Apiaceae (10). In the Phytosociological study, thirty-eight quadrats of one square meter were established along the roadsides. The species that demonstrated greater importance value were Paspalum notatum Flugge – Poaceae, Cynodon dactylon (L.) Pers. – Poaceae, and Facelis retusa (Lam.) Sch.Bip. – Asteraceae. Native species prevailed, totalizing 81.1%. The studied flora presented grassland and ruderal species.
