Any ideas on genus?

[Aussie42]

G'day all.

I like that message that appears if you haven't posted for a few weeks, kinda nice, so I figured I'd better get something up here or it'd be kinda rude ;-)

Now, I'm not sure if I'm asking about genus as such...family? I know this isn't a dendrobium, and while it's closer to a vanda my dad tells me I'm way off base there. It's not that much like a vanda - some similarities in the growth form and kinda sorta similar roots, but they're way too prolific with the roots to convince me it's a vanda.

I have 5 of these, I'm sure they're identical to each other. They're just coming back to life after a rough time (partly spent living for a few months in a shed with poor light and no water). I know it's probably impossible for an accurate ID until they flower, and that even then it may not be possible. But the family name would be good, and when they flower at least I'll be able to post the "help me" under the genus/family as opposed to a guess. And I may even be able to find them myself if I can narrow down the search a bit.

The good news is the reddish/purple cast on the underside of the leaves, which is more pronounced in good light. That might help a bit. Unusual roots, they will send perhaps 6-8 all at once, then they stall in their growing until the next set of roots appears. No sign of spikes as yet but my fingers and toes are crossed.

The largest of the plants - the one in the black pot pictured - is about 24 centimetres wide. For you non-metric folks, that'd be just under 10 inches or thereabouts.

Cheers,
Aus.

PS - please also excuse the photography. I'm working on it :-)
