This is Passiflora x Belotii. A sterile hybrid plant taken by myself in Tenerife. To me, Passiflora x Belotii is the most interesting plant due to its intense fragrance, tendrils, nectariferous glands, purple coronal filaments and what stands out most of all is that androgynophore, extending the reproductive organs.
