I hesitated posting this blooming but what the heck. It shows a solid red pouch which the stonei had a hand in. Also, the dorsal is basically white with strong stripping another contribution of stonei. These flowers are old as you can see the first has a brown spot starting.
Rick, nice to see these flowers but I'm wondering, this isn't the mislabeled plant you showed one or two years ago, isn't it? If I remember correctly were these flowers more colourful.
