Strange orchid identification

[hbc123]

Hi All,

I received this orchid from a friend a couple of days ago, and I am curious to know what orchid species or genera it belongs to and I have been searching hard online but still clueless.

Please see the photos of this orchid. The plant measures about 40-50cm in height, so it looks like a giant compared to my existing oncidiums. It has a rather long flower spike around 60cm that supports a cluster of greenish yellow flowers as shown. Each flower measures 4cm across.

Thanks for sharing your knowledge. I really like to know what it is so I am aware of what this new addition is.

Regards,
Herbert

Grammatophyllum scriptum, variety citrinum
(or very similar)

I'm sure someone will chime in and verify or deny it.

Take care
happy growing

I think its scriptum as well. The flowers seem a bit larger than the ones I grew, but that could be an artifact of the flowers being closer to the camera than the hand.
