Wild Flower in the Fareast

I bought an orchard in Thailand 7 years ago. This is the first time I see these flowers. Does anyone know what they are? Please help me identify this plant. I hope it is a rare plant. Thank you for your help.

Noi Buzenas

 

Where was the photo taken?

 

The pictures were taken by my gardener in Thailand.

 

Looks like a Uraria sp.

 

Thank you so much for your help, Tony. You are a genius!

 

Wow, Fabaceae, Legume family, not an orchid.

From the Uraria in Flora of China page, it seems to key out as Uraria crinita. If so, it doesn't seem to be rare. A page called My Nice Garden has photos and gives some names for it:

 

Wendy, keep an eye out for immature Trifolium or Lupinus flowering heads. If one of the species with a longer inflorescence, you'll see the resemblance.

 

This is a sure Asian foxtail (Uraria crinita). It has different kind of leaves. Here is the reference I found last night: http://akitia.com/หางกระรอก-v-หางหมาจอก-uraria-crinita/20/11/2008/

Thank you for your support.

 

I found more information on this site http://natureproducts.net/Forest_Products/Ornamentals/Uraria.html
