Hi elissamiranda,

to me it seems a Dendrobium lindleyi ( syn Dendrobium aggregatum) or a Dendrobium jenkinsii (Syn Dendrobium aggregatum var jenkinsii).
Both plants are really similar, very different flower, take a look at this link :

this is mine now




first photo to understand dimension and second to let you see stems on a jenkinsii, flower are held one by one, dend lindley has a few flowered inflorescence, both should be fragrant.
Both of them need a dry, cool, quite long (at least 2-3 months) and if possible full shine rest during winter otherwise will not flower.
Anyhow I have not kept it completely dry, al least once a week I sprayed it.
Mine was with cool dendro with t min during night around 10 C.
This is a small trick I have used this year for the first time after 2 years full of vegetation but no flower, (seems it works, I have many many stems, let's hope it will flower), when it has started with new root I brought it in my office, lot of light (but less then before, no full sun) and high t (18 night 22-24 day), in a short time it is covered with floser stems)
If you can mount it on a cork, I have used a mangrovia roots (one used for aquarium), it grows quickly, I place 5-6 pseudos on that piece in 2007 and it almost cover all the piece in 2 years.
