Ichang Papeda Flower

[citrange]

C. ichangensis seems to be very variable. I have one growing outside in England which flowers and produces a few fruits most years. The fruits contain no flesh at all - just stringy pith and large seeds.
The flower buds are tinged with purple and their stalk always bends over so the flower hangs straight down. I don't recall any other citrus that does this. 
Has anyone else noticed this trait on their Ichang Papeda? I wonder whether it has any purpose?

As usual, I can't add images to my posts here, so here are links to a couple of photos taken today.

The flowers of my IVIA clone look exactly the same. But the fruit of this variety is quite edible. Moderately sour, juicy with only faint bitterness. No seeds at all without cross pollination.

I'm increasingly of the opinion that the "ichang papeda" I got from Woodlanders is crossed with something else - my plant's leaves have a distinct olive green hue, are round at the tip, and have petioles much smaller than the main leaf. Your images make me suspect strongly that I don't have a pure strain. If my ever flowers I'll let you know how it compares to yours.

Your plants are lovely, btw.
