Solanum linnaeanum flowers

Solanum linnaeanum flowers are mauve to purple. They grow solitary or in small groups on hairy pedicels from leaf axils. The pedicels in picture are blackish purple like the upper stem, the short hairs upon them whitish. The green calyx lobes are bluntly pointed and ridged up the centre, covering the fairly narrow corolla tube up to before the five petals spread widely into a shallow bowl. The pointed petals form a wavy, poorly defined star-shape, fused lower down into the radially symmetrical corolla. Flower diameter is from 1,5 cm to 3,5 cm. 

The large, oblong, yellow or orange-yellow anthers cohere around the base of the green style, the filaments short. No styles are visible here. Where they do show, they are white, the stigmas at the tips small and head-like.

The sharp spines on leaves and stems are here mostly yellow at the tips, white lower down (Euston-Brown and Kruger, 2023; Curtis-Scott, et al, 2020; Manning, 2007; iNaturalist).
