Hi. I'm new to the list and enjoying it a lot. Does anyone out there know of a source for O. tetraphylla seed? Or, alternatively, a variety that has a non-brevistylous flower? (The commonly available species type, 'Iron Cross', and 'Reverse Iron Cross' unfortunately all have the same flower type, which makes them incompatible.) I've been hoping to do some breeding with this species, but need to get at least one variety with a different flower morph in order to kick off sexual reproduction. Thanks! Bill
