Thanks for pointing this out. I don't think that the seeds are likely to be 
hybrids, since my A. thunbergii flowers about three weeks earlier than A. 
kiushianum. However, the latter is closely related to the former and may wel=l 
exhibit the same germination pattern.

However, the plot thickens. I checked Gusman's section on A. kiushianum and 
on page196 discovered that I had informed him in 1999 that I had gotten 
immediate appearance of the eophyll with this species in '98. (My email to h=im 
confirms this) I confess that I didn't check my records, and hadn't rememberí 
growing it from seed previously.

Even more mysterious is that my record of the '98 seeds contradicts what I 
wrote him!! According to my notes I saw no eophylls until the pot had been 
refrigerated twice! 

I am at a loss to explain the discrepancy between my email to Guy (1-22-99) 
and what my database says. My database is very detailed about the various st=eps 
leading to the appearance of eophylls in   May '00 and is likely to be 
correct. That fact, and the current experience, would lead me to the conclus=ion that 
A. kiushianum doesn't produce the eophyll until the secong growing season. 
Sorry for the confusion, and apologies to Guy!
