E. citrinum tends to have more "shallow flowers is side elevation than howellii  but
you will see that  it is the auricles that are the defining feature. There are clear close ups in the Log showing the differences .  :)

Ray, for interest, can you post some pics of the inside of the various flowers?
ID can be tricky on these guys......they may be hybrids but, you know, while anther colour is sometimes given as a diagnostic, t it has been found that that is not always as firm a reason as first thought. There  can  be variations!  :P

Wonderful life, isn't it, trying to track these things down?  :-X

Ray,

How are the flowers arranged?  Could it be multiscapoideum?  If so, each flower appears to have a separate stem, with multiple flowers from a bulb.  They actually branch below the surface, so they are technically one scape, but that isn't how it looks.  I have them in flower at the moment as well and the leaves match that, although my flowers have a bit more in the way of throat markings.  I don't grow howellii so can't compare it.
Cheers.
