Short flower spikes on rescue oncidium

[Maxx]

As this is my first post on the board, greetings to everybody from Hungary.

Although I am relatively new to orchids, in the past half year I have amassed a lot of rescue all-kind orchids from garden centers and hypermarkets.

Out of these refugees, an oncidium-type (?) orchid decided to bloom (I have no clue which one) from its new growth, but as you can see on the pictures the flower spike is very small, and one of the buds already blasted.

Will the flower spike get bigger? An why is the orchid already blooming without the pseudobulb maturing first?

My growing conditions: western facing window, temp 75 F, humidity 60%, watering is weekly with 5 min soaking, fertilizing bi-weekly / monthly.

Thank you in advance for your valuable insights.

I don’t think that’s an oncidium. I cannot be sure of the genus, but there are many that flower on short inflorescences.

I agree with Ray, definitely not an oncidium or even any part of the oncidiinae family.

? Zygopetalum ?

My thought, as well, but I cannot be certain, as there are several genera with similar inflorescence presentations.

That's a good guess Deac!

I remember also to have purchased after Christmas last year the rescue Zygopetalum on the picture below. Do you know what species / hybrid it can be. Any idea when the pseudobulb will form, and whether the inflorescence will be larger?

Tbh those orchids with such roundish pseudobulbs all look the same for me without flowers Is there any description available how to distinguish them?

You were right guys! It turned out to be a Zygopetalum!

Can anybody maybe give me the correct scientific name of the species?

No this is unlikely...

It is a hybrid and to be fair these hybrids vary a bit so one might look like a different hybrid and so on.

Type in zygopetalum hybrid in google, choose one you think it might be but know that it might also not be.

I prefer to name my orchids even if it is not the correct name, as long as you don't start breeding with them I do not see the harm
