I've posted this plant before in the hope of getting it identified but we've not got there confidently yet. Two different seasons:

Lovely plants, which remind me of a question.

One of the most basic distinctions when identifying plants is whether their flowers are actinomorphic ('regular') or zygomorphic (irregular). In other words, are they radially symetrical - like a rose, a poppy, or a buttercup - , or are they only symmetrical in one , usually vertical, plane - like a snapdragon, an orchid, or a sweet pea?

Maybe I'm missing something, but isn't it unusual to find both forms in a single family of plants, as seems to be the case in the Cactaceae? I'm struggling to think of another family that does this - anyone have any thoughts?
