can anyone point me in the direction of a good plant/flower identification
guide?

my partner recently received a "cocktail bouquet" from www.tesco.com and
we`ve no idea what one of the flowers is

it`s a vivid red colour and from the side fans out to about a 4 inch radius
, but from the top is only about an inch across and looks like a cartoon
clam/oyster mouth

don`t ask me any complicated questions as i`m an absolute amateur !

i put the url in in case people want to see it (rather than post a pic)

thanks in advance :-)
