Trt. Kuquat (Trt. Splendidum x Trt. Haematochilum) These are more commonly known as mule ear oncidiums. This one is large (over 3 feet tall) and very fragrant. I have one other (Trt. (onc.) Maureen x Haematochilum Red) that I really like so I bought this second one because I don't see them very often.
