unknown orchid

[SJF]

Hi,
I bought this orchid last year. I repotted it a month or two ago. It wasn't due to bloom again, but it surprised me. Weird thing is that the blooms and buds are "stuck". Why did this happen? Does anyone know what the name of this orchid is? Also, the foliage has some spotting. Does it look fungal or like something else to you?
Thanks for looking

It is an Oncidium of some sort. There are so many hybrids in the Oncidium alliance that it is almost impossible to name an un-tagged one. The spots look normal to me. Many oncidium are very prone to spotting and yours looks minimal. I seem to get a lot of spots on mine. I'm not sure why since mine rarely ever get wet leaves.

The spikes can get stuck on these also and I think its when there is not enough humidity or they are a bit dehydrated. Yours looks a wee bit dry although many Oncidium type do get very wrinkled older pseudo-bulbs. So long as the newer growths are staying nice and plump it should be OK. Oncidiums like to be a bit moister in the pot than Cattleyas which should dry out before watering again. I saw your roots on the one you re-potted and it looked happy so I wouldn't change things too much as you seem to have good culture. I just check the newer almost mature growths and try to keep an eye out for new spikes in case they get stuck.

It looks like it has a number of Oncidium alliance orchids in it. Brassidium and Wilsonara look pretty similar but it is difficult to tell for sure which.

cold water droplets that the sun have used as a magnifying glass to burn the leaf....but as time passes the fungi used it as a feeding ground....wipe the leaf with llisterine mouthwash or vodka or any alcohol that evaporates in a couple of minutes and kills the fungi....hydrogen peroxide is also good....
silken is right, your plant is dehydrated by the looks of the shrivelling bulbs(you are using a mix that easily drain water=you need to water more)....try soaking the pot overnight then water your plant in the morning every other day and in the warmer months water it in the morning and in the late afternoon....
it is advisable to wet the underleaves with fertilizer but wipe dry with paper towel droplets on the leaves especially if it is cold....
this kind of plant can make flower spikes curl inside and sometime they dont develop in form when dehydrated....you can also look if the leaves are pleated then there is a moisture issue

*dont worry if your plant is a NOID....its got beautiful flowers thats all that matters....

Thank you for your tips. I appreciate it. Will the older bulbs re-hydrate? It was like that when I bought it and I must have left it pot bound too long too. The grower had it in black lava rock. Should I add some Physan for the overnight soak? Do you know how long Physan 20 stays active once mixed with water?
