Dendrobium types?

[King_of_orchid_growing:)]

They're not really keikis. They're what I like to call new shoots.

Think of it this way…

If the new growth develops up to when the roots are about 2.5" - 3" long and the shoot is about 2" - 4" tall; when you attempt to remove them and they come off easily by removing them using your fingers, that is a true keiki.

If the growth has grown to the dimensions I stated in this example, and they do not peel off the plant with your fingers, that is not a keiki, that is a new cane.

Okay, thanks for the info!

You can consider keikis as "bailout plants" that grow out of the "mother plant".

They separate from the mother plant eventually and can detach from any point of the cane rather easily when removed manually without the aid of cutters, knives, or scissors.

Well, those two growths will develop into canes, but I don't know if you would call them keikis or not... lol! I generally think of keikis on Dendrobiums being new plantlets a bit higher up on the canes, but these look like they are from the rhizome area. Six of one, half dozen of another?

This plant obviously likes what you've done for it!

[King_of_orchid_growing:)]

I've seen true keikis appear towards the base of a cane before. It doesn't happen frequently, but it has been known to occur.

Keikis can grow out of the "dormant eyes" at each node near each segment delineation along the cane.

I have a few perfect examples of what I'm talking about, with the true keikis appearing towards the base from 4 different genera of orchids.

Example #1:

Physothallis cylindrica - This species is a Pleurothallid. I don't know if people are aware of it, but this species keikis like no other when conditions are not to its liking, but does not outright kill it. I've seen keikis grow out of the apex of the stem where there is a little piece of meristematic tissue from where the plant would normally bloom out of. This little meristematic tissue is specifically located at the junction of where the stem joins with the petiole of the leaf. Another area this orchid can grow a keiki out of is towards the base of the plant, where there are a few "dormant eyes" located at the junction of the rhizome and the plant's true stem.

Example #2:

Epidendrum longicaule - This orchid is a keiki machine when conditions are not favorable, but does not outright kill the plant. It will keiki all over areas where there are nodes with dormant eyes. That includes keikis that appear towards the bottom-most segment junction/node where the rhizome joins with the plant's true stem.

Example #3:

Dendrobium kingianum - Talk about keiki machine, this species is it! When conditions are not favorable, but does not outright kill the plant, this orchid will throw out keikis like no tomorrow. Along with the keikis appearing towards the top few nodes of the cane, I've also seen a few, (rarely), true keikis appear towards the base of the canes at the bottom-most node/segment junction.

Example #4:

Restepia striata - Another one that throws out keikis like crazy. Same thing. Throws out keikis mostly at the top-most node/segment junction where stem meets the petiole. Also grows keikis out of the base towards where the stem meets the rhizome.


Keikis are best defined as plantlets that grow out of the mother plant, but eventually will become their own plant. They are not the same as divisions.

Thanks for all these examples. I have a Dendrobium kingianum and its growing new keiki's.

[King_of_orchid_growing:)]

If they eventually can be peeled off with very little effort, then they're true keikis. If not, then they are new canes. With Dendrobium kingianum, it's not clearly evident at times. With some experience, you can tell the difference.

Btw, Dendrobium kingianum grows as a lithophyte, (grows on rocks), in the wild. The type of rocks they grow on are granites.

Like I said prior, Dendrobium kingianum very rarely grows a keiki towards the base, but it can; so when it does, you will recognize it. It will look subtly different from a new cane.

Btw, I think the Dendrobium kingianum in your pic might not have any basal keikis. From what I see they are what I'd call new growths. I had to kinda mull it over a bit to decide whether yours were displaying keikis or not, since they're not in my possession.

There might be one thing that resembles a keiki that is growing lower down than normal, but I'm not sure if it is a keiki or not.

Oh, and if anybody is wondering what section Dendrobium kingianum is in; it's in section Dendrocoryne.

Oh, neat! I got this plant on June 6th and in just a month its shot out all those new growths. Here is an image of what it looked like on June 6th 2014.




These two images are from 6/29/2014:


sideways view:

[King_of_orchid_growing:)]

The front-most growth that is in the 3rd pic might be a keiki. If that growth is connected to a larger cane, then it is a good possibility that this is a keiki, and it is growing much lower than it normally would.

If it is a photographic example of a keiki, notice how it is growing out from a node/segment junction.

Are you intentionally growing Tillandsia usneioides, (aka "Spanish Moss"), with the Dendrobium kingianum? Tillandsia usneioides is not a true moss, it is a bromeliad, which is a flowering vascular plant.

Dendrobium kingianum grows in the woodlands of certain parts of Australia, it doesn't really need to be grown in high humidity situations.

I had just stuck the Spanish moss in there to increase the humidity early on. I didn't realize they didnt need it. Should I remove it?

That is a really cool picture of them in the wild.
