I grow these orchids in my garden without any special care because they are native to Argentina.
The first one is an oncidium longicornu. The blooms are very small. I grow it on a piece of branch.
The second one is an oncidium divaricatum. It has very long inflorescences. I´m holding the pot in the first picture to show you how long they are. The second photo is a detail of the flowers. I didn't take these photos this year. They were taken three or four years ago
