Bulbophyllum makoyanum

Bulbophyllum makoyanum (Rchb.f.) Ridl., Mat. Fl. Malay. Penins. 1: 81 (1907).

Cirrhopetalum and Trias have recently been reinstated back into Bulbophyllum. B. makoyanum is extremely variable in the size and shape of the flower parts. There is a recognised variety brienianum some authors give this variety species status. Distribution Borneo and the Philippines. I name mine 'Wagon Wheels' it's easy to grow and it just rolls on.
