This is a vintage botanical illustration of a giant water lily, likely the Victoria amazonica. The central focus is a large, circular water lily pad, partially cut away to reveal the underside with its ribbed structure. A massive, bulbous flower bud is emerging from the pad, half-open to show a creamy white interior and a darker, textured edge. The water around the lily pad is rendered with delicate, linear strokes, creating a sense of movement and texture. The reflection of the lily pad and flower is visible in the water, adding depth and realism to the scene. In the background, there are hints of other lily pads and a distant shoreline. The overall style is detailed and precise, typical of botanical illustrations from the 19th century. The color palette is muted, with shades of green, brown, and cream dominating the composition. The illustration is signed in the lower right corner, and there is text along the bottom edge.
