new term request: Hull

[peter.stevens at mobot.org]

I agree with Toby - second would include all sorts of things, and 
third is difficult - the K of raspberries barely is enlarged at all, 
and is basically marcescent - marcescent calyces are common, and 
nobody ever calls then a hull (and I hope never will).
