Hello everybody, now I have some random identification requests, if anybody has a clue of what there complete names are;
Thank you very much!!

I would think they look like "species" orchids, so would not have any cute side name.

The first is a Scaphyglottis, but I wouldn't guess as to the species.

In what way do you think the others are NoIDs? The photos of Prosthechea michuacana and Oestlundia luteorosea appear to be properly identified as to species.

Arpophyllum medium is considered to be a synonym of Arpophyllum giganteum, and also appears to be correct in that sense. Not finding a picture labeled Arpophyllum medium to compare it to, I might have matched it to Arpophyllum alpinum, but that is also sometimes considered a synonym or subspecies of Arpophyllum giganteum.

Thank you very much @PaphMadMan (dont know how to tag yet) I just wanted a second opinion on what I guess each one was, glad to know they also match to your criteria, and thanks a lot with the Scaphyglottis confusa search in a local database for the genus and found the species, had no clue even from where to start at!
