I guess I will dispatch this...

someone in the Name that Plant forum actually identified my mutated plant part photo as a 'pantaloon'. I was surprised to find that these things and several others mutant combos have names.

I found another occassion to post this elsewhere, and I thought of this post.

Since posting this I have learnt that such an oddity is known as a "homeotic mutation". There is an interesting discussion going on in the daylily forum about a daylily with petaloid leaves.

Here is a rose with the same phenomenom going on.

Thanks for the photographs and the further information. Plants and their antics are endlessly interesting to me...josh

They are found fairly commonly among cultivars of some plant groups, for example azaleas. Sometimes described as "hose-in-hose" (which may go back to the time when hose meant sock or stocking).

O. F. Cook (1926) called these "Metaphanic Variations". There are lots of them around if we bother to look. I have seen tulips with an extra organ - part leaf, part petal - on the stem where no such organ belongs. And I have seen agapanthus with the spathe-valves colored the same shade of "blue" as the flowers. The so-called Green Rose bears a rosette of green sepals blotched with red in place of petals and stamens. Then there was a daylily with a leafy 9 inch bract.

Petaloid stamens, stamenoid petals, nectaries on leaves ... the list goes on and on.
