This was first described by Reichenbach as from Brazil and 
figured in the ‘ Botanical Magazine’ without locality. It is not 
common in the peninsula, but seems to be plentiful in Borneo. 
The plant varies a good deal in the form of the pseudo-bulb ; 
one form has large thick approximate bulbs usually four-angled 
and broad elliptic leaves ; the other has a slender rhizome, small 
distant pseudo-bulbs, and narrower lanceolate leaves. What 1 
take to be Rolfe’s C. Brienitanum is only different in colour. I 
have compared both plants, the spotted one, C. Makoyanum, 
Reichb.f.,and C. Brienianum, Rolfe, very carefully,and cannot see 
any constant difference in form in any part, and as the colouring 
of the typical one varies a good deal, I put Brienianum as a 
variety. 
Both forms come from Borneo as well as the peninsula.

I have not met with anything answering to the description 
of this, which is described as having two-leaved pseudo-bulbs, a 
thing unknown in any Cirrhopetalum or Bulbophyllum. The 
type specimen in Herb. Buitenzorg consists merely of a portion 
of the scape without the flowers.
