Orchid help needed for Miss Marple (UK TV show)

[marple]

Hi,

I am working on a British TV show called 'Miss Marple," and am in need of some advice on orchids!!

Firstly - in the script, (which is set in 1955) it describes one of the characters cross-pollenating some orchids - could someone tell me how this would have be done? Is it like with other plants where you use a brush etc?

Second question - there is a 'snake' orchid mentioned - and another character says something along the lines of 'ooh yes it does look like a snake, doesn't it?' - could someone advise me as to what orchid might be suitable for this? I have tried googling but a number of orchids come up...

Many thanks - all help is greatly appreciated!!

Best wishes,

Naomi
