Whereas in many rosids, contort petal aestivation is enantiomorphic
, in almost all asterids contort aestivation is fixed to one of the two possible morphs at genus or even family level (Endress, 1999, 2001a).
The fully shaped enantiomorphic
characteristic of a biological object is decisive for subsequent development, and for all the major parameters of living organisms (see figure 13).
It's going back to the idea of my Enantiomorphic
Chambers , which is a similar kind of double thing.
Recalling the "abysmal" symmetry of Robert Smithson's Enantiomorphic
Chambers, 1964, these sometimes made the viewer appear to vanish, as two incomplete surfaces visually interlocked, via reflection, to complete one another.

Chambers back into existence--but this time only as reflections.
