epidendrum stanforme

[Bindi]

Hai there,

I don't think the plant has a disease. I would cut of the leaf that seems thorn (on the second pic). The medium seems old, so I would repot it. The other leafs look like they had a spidermite attack. This can be overcome by wiping the underside of the leafs with a wet paper towel on a daily basis. Keep it out of the sun and keep humidity high until the plant recovers and forms new roots (some leafs look withered).

good luck, Bindi
