Dendrobium species ID

[Surjasama Lahiri]

I have these dendrobiums.

The initial two (in the same picture hanging off trees) are with me for about 4-5 months. The left one is developing keikis.

The other two orchids in the other photo are with me for about one month. One is flowering and I managed to develop the flowers. It bloomed today.

Blooming pictures later. Can anyone help me ID these dendrobiums??

Thanks!

Hi Surjasama, nice-looking plants!

In your first photo, I'd guess Den. aphyllum (formerly known as pierardii or cucullatum) for the pendant one on the left. Keep it cool, bright, and fairly dry for the winter and it should bloom very nicely in the springtime. They sometimes keiki a fair amount, which many say is from keeping them too wet or overfertilized in the winter. My experience raising a few juvenile aphyllum makes me think it's more complicated than that, but I also don't mind a few keikis so I haven't worried about it much.

The other plant in the first picture looks like a Den hybrid involving sections Spatulata or Phalaenanthe, but again can't say conclusively out of bloom, and if it's an unlabeled hybrid it will be impossible to ID conclusively.

In your third picture the one on the left looks like another Phal/Spatulata-type Den and the one on the right like Oncidium or a relative, maybe something with Miltonia or Brassia in its ancestry.

I have the one in the later pic blooming right now. Will post a picture of that.

Agree. The one in the green basket in the last photo is definitely an oncidium relative.

Photos #1 & #2:
It could be any of a number of pendant growing Dendrobiums:

pierardii{aphyllum]
anosmum
crystallinum
and any of several others.

The leaf shape can vary, even within a species.

Photo #3 again could be any of a number of Dendrobiums with shorter upright PBs.
It looks as if there is a spike growing from the top of one of the PBs.
If so, It may be a Phal. type Dend.

Pics of both of them in blossom should allow an ID to be made.

EDIT:
In pic#3:
Being as you asked about Dendrobiums, I've assumed you are not asking about the Oncid type, but about the one further back.

A big thumbs up to you guys for replying to my post. I've been busy otherwise and could not catch up with the thread. I'm posting a picture of the blooming dendrobium, earlier shown in the photos!


Lemme know if it is possible to ID now, with the flower on!!

Cheers!!

sure looks and acts like a properly grown den lawesii..if it drops all its leaves it just might be that in fact, if it blooms we will know for sure
