Drosera viridis is a semi-erect or rosetted perennial species in the carnivorous plant genus Drosera. It is known only from Brazil, being found in eastern Paraná and São Paulo and central Santa Catarina at elevations from 550–1,100 m (1,800–3,610 ft). It may, however, also be found in adjacent Argentina, Paraguay, and Uruguay. It typically grows in waterlogged habitats among grasses in white-clayey, reddish lateritic, or humus-rich black-brown soils and is sometimes found submerged with only the leaves above water.[1]
Drosera viridis produces carnivorous leaves that are spatulate, about 5 to 28 mm long, and entirely green, even when exposed to full sun, unlike the related D. communis whose leaves turn red in full sunlight. Each plant produces one to three erect or ascending inflorescences, which are 7.5–30 cm (3–12 in) long, including the scape. Each inflorescence bears two to twelve light to dark lilac-colored flowers. It can be found flowering year-round, though more plants are in flower during the wet season from December to March.[1] This species has a diploid chromosome number of 2n = 20.[2]
Drosera viridis is closely related to D. communis and often occurs in the same regions with it, but D. viridis is restricted to a more narrow range of wet habitats. Where D. viridis and D. communis are sympatric, a few specimens have been found that may be hybrids, though they were weak, indicating that the resulting hybrid cross between these two is rare, infertile, and may not reach maturity.[1]
This species was first described by botanist Fernando Rivadavia in a 2003 issue of the Carnivorous Plant Newsletter, along with three other new Drosera species from Brazil. The type specimen was collected by Rivadavia and M. R. F. Cardoso on 2 February 1996.[3] Other specimens were grown under greenhouse conditions for further observation. Rivadavia chose the specific epithet viridis to refer to the green color of the plants even when exposed to full sun.[1]

Drosera viridis es una especie planta perenne, semi-erecta o en roseta, carnívora, de la familia Droseraceae.
Sólo se conoce en Brasil, siendo hallada en el este del Estado de Paraná y Estado de São Paulo, y en el centro de Santa Catarina, en elevaciones de 550–1,100 m. Sin embargo, también puede encontrarse en Argentina, Paraguay, y Uruguay. Crece habitualmente en hábitats anegados entre hierbas, y en suelos arcillosos blancos, latéricos rojos o negros ricos en humus, y a veces puede encontrarse sumergida con solo las hojas sobre el agua.[1]
Drosera viridis produce hojas que son espatuladas, de entre 5-28 mm de largo, y completamente verdes, incluso expuestas al sol directo, a diferencia de la Drosera communis, cuyas hojas se vuelven rojas a pleno sol. Cada plantas produce entre una a tres inflorescencias erectas o ascendentes, que tienen 7.5–30 cm de largo, incluyendo el escapo. Cada inflorescencia posee entre dos y doce flores de color lila claro a oscuro. Puede hallarse floreciendo durante todo el año, aunque más plantas estpan en floración durante la estación húmeda de diciembre a marzo.[1] Estas especies tienen un número de cromosoma diploide de 2n = 20.[2]
Drosera viridis está estrechamente relacionada con Drosera communis, y a veces coinciden en las mismas regiones, pero D. viridis está restringida a un rango más estrecho de hábitats húmedos. Donde D. viridis y D. communis son simpátricas, pueden encontrarse algunos especímenes híbridos, aunque si son débiles, indicaría que la cruza híbrida resultante entre esas dos es rara, infértil, y no se alcanzará la madurez.[1]
Esta especie fue descrita por primera vez por el botánico Fernando Rivadavia en una edición del Carnivorous Plant Newsletter de 2003, juntos a otras tres nuevas especies de Drosera de Brasil. El espécimen tipo fue recolectado por Rivadavia y M. R. F. Cardoso el 2 de febrero de 1996.[3] Otros especímenes fueron cultivados bajo condiciones de invernadero para su posterior observación.
Drosera: tanto su nombre científico –derivado del griego δρόσος (drosos): "rocío, gotas de rocío"– como el nombre vulgar –rocío del sol, que deriva del latín ros solis: "rocío del sol"– hacen referencia a las brillantes gotas de mucílago que aparecen en el extremo de cada hoja, y que recuerdan al rocío de la mañana.
Rivadavia eligió el epíteto específico viridis para referirse al color verde de las plantas cuando son expuestas a sol pleno.[1]
