This is described wiih olive-green flowers, flecked wilh goiden. Lip white, wiih 

 brown and violet flecks and bands. Iis affinity is undoubiedly with 0. phymatochi- 

 lum ; but its laieral sepals are connate at the base, and its petais are three limes as 

 wide; on which accouot it would rather seem referable to ihe Telrapctalous macro- 

 peialous group (see p. 17). My specimen, for which I am indebted to Prof. G. Rei- 

 chenbach, is a porlion of a long zigzag panicle, the bracts of which are almost ob- 

 soleie. The flowers are much smaller than in 0. phymatochilum , and apparently of 

 a firmer texiure. The lateral sepals are linear-lanceolate . canaliculate, uniled for 

 about a quarter their length, and longer than the oiher parts. The dorsal sepal and 

 petals are alike lanceolate acuminate and recurved as weil as chanelled ai the «nd; 

 but the latter are at least twice as wide. The lip is hastaie wiih ihe lateral lobes 

 rounded, passing into an inversely cuneate isihmus which expands into an ovate lobe, 

 njuch narrower tban tbe base. The crest consists of six thick sbort plates , tbe 

 middle basal one of whicb has a slightiy elevated crest. The column has a pair of 

 very prominent narrow cheeks; its wings are reduced to a pair of pointed rudiments 

 opposite the base of ihe btigmaiic cavity. It would seem to be a very preity plant 

 when fresh.

The flowers are too diminuiive to render tbis u.seful to cultivators; they are 

 wholly yellow, excepi the crest and base of the lip, wbich are reddisb-brown. Some- 

 times ihe panicle becomes leafy, with a few ecattered flowers only at tbe eod 

 of its brancbes.
