A tall dense erect branchlng panicle belongs to this, whicb has ihe lower sepals 

 much narrower than ihe petals, which ore rather broader than the dorsal one. iis 

 crest consists of three to five short plaies at the base, and three oihers in front, di- 

 verging and irregularly lobed ; arround which are several oiher processes , besides 

 a few varicosities towards the edge of the lip, It was formerly cultivated by Mr. 

 Darker', who called it 0. anomalum , because its fiowering stera grew from the apex 

 of the pseudobulb. Flowers large , brilliant yellow, with the isthmus of-ihe lip and 

 the sepals and petals blotched wiih ihe richest chocolaie in one variety, and dull 

 red, green outside, in another. A very fine and compleie specimen in my herbarium 

 shows how variable the flowers are in size, some on the same panicle being hardly 

 lialf an inch across, while others are niore ihan an inch. It has evidently a tendency 

 10 pass into the dimorphous state. After the most careful esamination of the original 

 evidfince, I can come to no oiher conclusion ihan ihat all the supposed species, now 

 reduced to one, are raere forms of one anolher, I also fear thal 0. caldense. (n, 171) 

 must.be reduced lo ihis. That all are iirnzilian is unquesiionable ; and yet it is as- 

 serted in gardens ibat some comc from Mexico. Rchb. refers 0. stenopetalum of 

 Klotzsch to tbis species.
