The six varieties and forms of Silene antirrhina noted above were named on the basis of stature and flower color, but none appear to be worthy of recognition. The species is very plastic, being greatly affected by moisture, exposure, and nutrients.

Silene antirrhina
(
Inglês
)
fornecido por wikipedia EN
Silene antirrhina is a species of flowering plant in the family Caryophyllaceae known by the common names sleepy silene[1] and sleepy catchfly.[2] It is native to the Americas, where it is widespread throughout North America and parts of South America. It is known in Europe as an introduced species.
It can be found in a wide range of habitat types, including disturbed and recently burned areas. It is sometimes weedy.
Description
Silene antirrhina is quite variable in appearance, its morphology depending on several environmental factors, such as moisture level and available nutrients.[3] In general it is an annual herb growing erect to a maximum height near 80 centimeters (31 in).
The slender stem grows from a taproot and branches near the top. There are dark-colored internodes on the stem, the upper ones often glandular and sticky in texture. Insects become trapped in the sticky patches on this protocarnivorous plant, but it does not obtain any nutrients from them.[4] The lance-shaped leaves are up to 6 centimeters (2.4 in) long near the base of the stem, and are smaller and narrower farther up.
The flower is enveloped in an inflated ovate calyx of fused sepals with ten veins. The calyx is open at the top, often revealing five double-lobed petals in shades of pink, red, or purple to white; the petals are sometimes absent.
