I have just seen a topic in Non Edible Plants, mentioning Chincherinchees.
I first saw these flowers, when I was serving my apprenticeship as a florist - more years ago than I care to remember!!!!
They were called the Rattlesnake flower, because, apparently, when they were growing in the fields (was it in South Africa?), when the wind blew through them, they made a noise like a rattlesnake.
Funny, the things which stick in your mind, isn't it.
