Asclepias praemorsa flower

An Asclepias praemorsa flower has its corolla lobes joined at the base, widely spreading in the middle parts but ending up in a shallow bowl as the lobe upper parts curve in. The corolla lobes are not reflexed as far as those of several other Asclepias species flowers. They have tiny, pointed tips, each flanked by two shoulder-like curves at the height of the tips, bent back on the side, rendering the broad-based lobes ovate to oblong. The lobes are slightly fleshy on the inside, creamy to limy yellow or beige.

Invisible in picture, the tiny, narrow sepals behind the corollas are pointed, persistent on the fruit.

Inside the corolla the five spoon-shaped or boat-shape corona lobes spread, roughly over the gaps between the corolla lobes, their tips darkened. The central, staminal column appears still undeveloped in this flower. The large anther appendages are strap-like (Pooley, 1998; iNaturalist).
