Description

Silene invisa is a perennial herb growing up to about 40 centimeters tall from a leafy caudex and taproot. The linear or lance-shaped leaves are a few centimeters long low on the plant and smaller farther up the stem.

The inflorescence is a solitary flower or a cyme of up to three flowers at the top of the stem. Each flower has a bell-shaped calyx of fused sepals lined with ten green veins and covered in short, glandular hairs. The strap-shaped or rectangular petals have blunt tips or may be notched. They are whitish to pinkish or lavender and sometimes barely protrude from the calyx.
