help identifying (possibly) scented orchids

[jt196]

Please!

I'm just getting started with orchids so need a little help. I bought these orchids as bulbs on a holiday in the lovely island of Madeira. Unfortunately there wasn't really any identification with them apart from saying that some of them (if not all) were scented orchids.

I'd love to know what they were so I can take better care of them. They seem to be doing ok as I got them in May and none of them had leaves on them, (apart from the first) and now all seem to be doing pretty well.

My best guesses so far with some image searching are:

1. Odontoglossum
2. No bloomin idea-um
3. Lycaste - although it looks like there's two different types in there from those leaves. Perhaps they're both different types???

Thanks in advance - and looking forward to making lots of use of the forum!
