Dear Jim S,
	Good point. I agree these are multipetalled, rather than 
'true' doubles, but the only multipetal Lycoris I can recall is the 
double radiata and no other multipetals.

	I wonder how many bulbous genera have BOTH true doubles AND 
multipetal forms.  Any guesses?

	Does anyone need definitions of multipetal versus double?

Some general definitions - but there are many exceptions, variations 
and unique examples -

Single Flowers -Those with a standard set of floral parts - 6 petals, 
or 3 standards and 3 falls, 6 tepals etc for that variety of plant. 
Full sexual parts.

Semidouble Flowers - Those with more than the standard number of 
floral parts and some of the sexual parts missing and transformed 
into petal - like structures. May or may not be fertile.

Double Flowers - Those in which all flower parts are transformed into 
petals or petal-like structures. No sexual parts. Infertile.

Multipetal -  Flowers that have extra parts such as 8 instead of 6 
petals, extra sexual parts, extra stigmas etc. These can vary from 
just a few extra petals to many, but flower parts are usually 
identifiable without transformation into petaloids. aka polypetalous
