Intergeneric Hybrids

Mary sue,

the hybrid genus for Hippeastrum and Sprekelia is Hippeastrelia.  There
were, also, entries made under Sprekeliastrum and Hippeasprekelia, but the
current usage tends to the first name.

Apparently, there is no protocol for placeing names together for a hybrid
genus.  In the Orchidaceae there are new hybrid genera registered almost
every month!  Due to the complexity involved, some rather inventive names
have been produced.  Indeed, there is a method to the madness, but any
previously proposed rules have proven less than effective when it comes to
creating names.  the trick would seem to be simply making it clear.  The "x"
before the hydrid genus is not used under orchids, but is typical for other
plant groups, just as is its use for species hybrids.

Great to hear your cross flowered.  Very exciting.  Is it relatively dwarf
in habit?  This is mentioned under the few notes on Hippeastrelia I have

also, once a hybrid genus is created and in use, all similar hybrids will be
placed under this new genus name.  It technically should be published, just
as any new species would be, but the practice is rarely followed.
