Calotropis is described as an example of which aestivation type?

Explanation:
Aestivation describes how the floral parts are arranged in the bud before they open. In valvate aestivation, the edges of the petals meet one another along the seam without overlapping. Calotropis has a five-lobed corolla whose margins come together edge to edge in the bud, not folded over or overlapped, so it fits valvate. When the flower opens, the lobes spread outward, but the defining bud arrangement remains edge-to-edge contact. This differs from twisted (where petals overlap due to twisting), imbricate (where petals overlap like shingles), or vexillary (a banner-planted arrangement seen in peas), which aren’t characteristic of Calotropis.
