Carlos, welcome to OB! (bienvenido al foro!
)
identifying the genus (and in some cases the group within the genus) to which your plants belong would be enough in most cases to know how to care for them. As Nicole already said, Photos would help a lot (however, I think you have most the work alreday done
)
Now, identifying hybrids without a label is almost impossible in most cases. Especially complex Phalaenopsis, Cymbidium, Oncidium and Dendrobium hybrids, which are what I suppose you have. Not even finding a photo in internet which looks "exactly teh same!" is a warranty you have identified the plant... there are many many many hybrids outthere which look very similar to each other and are impossible to say appart! Furthermore, many complex hybrids can have such a strong variability in form and color that two sister plants would look like completely different crosses!
The best approach here is keep your plants as NOIDs (No ID) and add a personal name of your taste to give them some ID, which would be valid mainly for you...
