Unknown epiphyte, suspected orchid, ID unknown

[paulindr]

I was just given a plant by a friendly seller of mostly succulents. I attached an image. Roots are very fine. the leaves shout orchid. I suspect the roots do too, even though they are so thin. But exactly what it is escapes me and my plant friends (including botanists). Isochilus was suggested but I couldn't find one with the same degree of leaf overlap. many thanks for help with an ID.

Could be a lockhartia. That's my best guess amyway.

[Roberta]

Lockhartia, perhaps?

[Mztrjoe]

There are many orchids that have a similar growth but until you have flowers it will be difficult to narrow it done to one family. Do you know where it might have come from? You could look at Dichea and Lockhartia.

[paulindr]

OK all. Lockhartia definitely looks almost identical in leaf bit I take Mztrjoe's Avatar
Mztrjoe's point about Dichea's similarity and needing to wait for flowers. However, I have two names, thanks to you three, so I'm a lot closer and feeling very happy! Thanks Katrina, Roberta and Mztrjoe. (And now I'll go check out Dichea)

I doubt it's a lockhartia or a dichea myself... looks like a section of dendrobium (love these imbricated types) that aren't often seen... like anceps, although anceps doesn't grow as long... lobulatum? There are quite a few species... I'd have to look up... but yes, waiting till flowers is your best thing to do... ok, just looked it up, section aporum...

[Roberta]

Good suggestion! Those leaves are rather succulent to be Lockhartia, etc.

[RobS]

I would also go for Dendrobium.

Reminds me of Dendrobium indivisum. Section Aporum since no terminal inflorescence seen

[King_of_orchid_growing:)]

Most likely Dendrobium in Section Aporum.

The other possibility, but less likely because of the rarity by which they are imported would be a "sawtooth leaved" Eria sp.

Dendrobium and Eria are closely related, btw.

Without a flower, it is difficult to pinpoint down to species. Some species, (not all), have very similar looking leaves to the ones yours has, and the leaves are also similarly arranged. The biggest differences would be in the flowers they produce.

If you want possibilities of species within the genus Dendrobium, Section Aporum, they are:

Dendrobium anceps
Dendrobium indivisum
Denrobium keithii

If you want a possibility of which species within the genus Eria, Section Aporodes it could be:

Eria aporoides

100% not Isochilus or Dichaea.

Dichaea looks fern-like and have thin leaves. In general, they do not tolerate low humidity very well. (I know that Dichaea glauca can grow in lower humidity levels better than the smaller species can.)

Isochilus are also thin leafed. To my knowledge, there are no succulent leafed Isochilus spp.
