Dendrobium atavus

One of my backyardigan, the dweller of the backyard. The plant grows vigorously, but the flowers not last long enough.
I have another one in buds too.

 

P.s. Too many 't'. It should be atavus

 

Thanks for removing a t
I might be wrong about how long the flowers last. They have just opened this morning. And while I was taking pictures a flower dropped. Seems that's an abnormal condition. Will update later...
And here is the dropped flower

 

Day 2. So, they only last for a day.

 

Back to check some smell. It has smell, not nice though. And here is another bloom

 

Actually it's not that huge Greg. The longest stalks are less than 50 cm.
