Suddenly got lots of orchids!

The pink one looks to be a similar shape and colour range of some of the Burragearas, Vuylstekearas or Beallara type from the oncidium group. There are many complex hybrids that mostly take similar care. Usually intermediate to cool growing with intermediate light. Most don't like to dry out completely or for long periods of time but have thin roots, so shouldn't be soaking wet either. Nice flower!
