I'm just about sure you are right in saying that Lycoris squamigera is
reproductively isolated from other Lycoris; but the reason it is
reproductively isolated is that it does not reproduce sexually. Or 
are there such things as sexually reproducing Lycoris squamigera? 

I've always assumed it to be a clone. 

I don't have a problem with species which arise via hybridization, as long
as they form sexually reproducing units. To me, that's just a nomenclatural
problem: the parental species in those cases are really themselves
conspecific, and the proof of that is the ease with which the purported
"hybrid" species forms a sexually reproducing unit.

This happens because "bad" botanists have given species rank names to
populations which, although they are different in appearance, are really no
more different than breeds of domesticated animals such as dogs.   

Also, to my way of thinking, it makes no sense to call an entity which does
not reproduce sexually a species. If there is not a sexually reproducing
entity which corresponds to what we know as Lycoris squamigera, then it's
not a species.

Hi Jim McK, and all,

Get a copy of the Chinese paper (in English) on Lycoris species from Jim 
Waddick, if Jim W. still has any left.  Since the hybrid origin is not all 
that clear (as far as I can recall -- wait for someone to do DNA) I suspect 
that the only properly published name is squamigera.

In any case, it seems that new species arise by hybridization in 
nature.  Since L. squamigera is reproductively isolated from other Lycoris 
species including, I presume, both its original parents, it is probably a 
good species anyway.  Hybrid origin per se would not disqualify it; 
reticulate evolution in action.  I think there are parthenogenic 
(apomictic) species of Zephyranthes (rain lilies) that are considered good 
species botanically.

I don't have bloom size squamigera planted here, but I have one scape each 
showing on LL. sprengeri, chinensis, and longituba.  More should be popping 
up any day now.

Regards,
Jim Shields
