Hi Jim & All, June 24, 2007
When all else fails, consult the manual; Gray's Manual in this case.
_Sorbaria sorbifolia_ is a distinct species, introduced from Central
Asia.
Some hybrids between _Sorbus_ and _Aronia_ are called _Sorbaronia_,
other hybrids X _Pyrus_ sp depending upon state of the 'Genera' at the
time. There are apparently many such hybrids; e.g. _Sorbus americana_
with _Aronia floribunda_ to yield _Sorbaronia jackii_ and with _Aronia
melanocarpa_ to yield _Sorbaronia sorbifolia_ and so on......
These hybrids between 'Genera' are less remarkable if one follows
Fernald and lumps them all (_Malus_, _Aronia_ and _Sorbus_) into _Pyrus_.
