Stanhopea Noids - Orchid Board

Mick Gooch · #1 03-07-2008, 04:15 PM

I have these three Stanhopeas which I would like to ID.

There are two Saccata types which may be the same and either Nigrov or Tigrina. Any ideas would be much appreciated.

Regards

Mick

Those look great! Sooo odd. What kind of medium do you use?

Sorry I'm no help with the ID.

Hi,

I currently use coconut fibre but I find they will grow in anything that is open and dries out in a day or so. Sometimes I use smallish bark, perlite and expanded clay "balls" - I would advise against plain bark or anything that retains water too long - works for me, but there are many experts here, especially in the Stanhopea forum, I'm just a hack

All right! Another fellow hack! Good to have you here. I'm always curious what others are doing out there. So many ways of achieving the same goal. That's why I love this board.

So, you let them dry out pretty fast, then drench them again? Also, I've read conflicting info on light requirements. Any more tips?

Here is tigrina - IOSPE PHOTOS
Here is nigroviolacea - http://www.orchidspecies.com/orphotd...roviolacea.jpg
and here is an Orchid Species article and Stanhopea species - Stanhopea
I hope this helps

Hi Mick!

The first one is a Stan tigrina, 'nigroviolacea' is only a trigrina variety, according some authors (w darker color and bigger size); another possibility is a tigrina hybrid (the dominance of trigina is impressive in its hybrids!). #2 and #3 pics do not show the 'perfect' angle to see the lip; for me its difficult to confirm the 'group', as you stated (Genus Stanhopea, Subgenus Stanhopea, Section Saccata), the 'horns' seems too thin for Section Saccata....in this Section the possibilities are Stan saccata, Stan radiosa or Stan pseudoradiosa, but I need more pics showing the lip in different positions!
Congrats, nice Stans!!

Many thanks, I had a fair suspicion it was Stan tigrina, 'nigroviolacea' but just wanted to check
Thanks

Ta, I found the Stanhopea page, beautiful

Nothing special - I have them under trees and also in 75% shade. I just water and fert with all the others but I think wet feet is a real setback for mine. I pot they flower but we are in Queensland, Australia temps 0 - 40 C.

I have heard that they like dolomite and that it induces better flowering ?

Regards Mick

Try these, not the best but they may assist. There are two of each. The only real difference to untrained/ignorant is the blotching in the orange "pouch"
