My new orchid

The other day while I was at the fruit market close to where we live, I saw a lady near the entrance of the market selling different kinds of  plants. As a  a plant lover, I thought to check out the plants before going inside the fruit market. I know prices with this kind are quite cheap compared to the prices in the plant nursery.While checking the plants,  I saw these orchids in a pot. I asked the lady how much was the price and I can't believe when she told me that it only cost $5 so, I didn't let my chance slip by and grabbed the plant.

I haven't got this kind of orchids yet and I thought it would be a great addition to my collection. The name of this orchids is brassia verrucose and it has white flowers as what the lady said to me.
Searching in the internet when I got home, I found out that the flowers look like in the photo below.
