Hymenocallis liriosme (?) and variants

Hi Adam, Joe, and all,

The Hymenocallis occidentalis and liriosme plants I have here show one 
significant difference:

H. liriosme blooms in spring, the scape emerging with a new flush of leaves 
in many cases.

H. occidentalis (a.k.a. caroliniana) blooms in summer, mid July to mid 
August.  The leaves are by that time old, and may even already be 
gone.  Gerald Smith has sunk "caroliniana" as a name for 
occidentalis.  See: Flora of North America, vol. 26, p. 283ff. (2002).

The number of buds on a scape seems to vary from plant to plant.  I suspect 
that under optimal conditions, there would be a fairly consistent maximum 
number; but my conditions vary too much from year to year for me to make 
any credible observations.

H. occidentalis is hardy here in central Indiana.  I have not tested 
liriosme extensively, but I have one clump growing in the ground outside 
the south end of my greenhouse.  This plant comes up each year, but so far 
I have not had flowers on it.

My liriosme often bloom in the greenhouse after a winter of having been 
stored pretty dry.  They are not trying to bloom yet this year, however.
