The grassy leaves often as long as ihe erect panicles aUhough somelimes much 

 sfiorier, give it a peciiliar appearance, added to which the sepals and petals are a 

 dull oiive brown without any spots, except at ihe point, wiiere they are yellow, wbile 

 ihe iip has also but one dull olive brown without any spots , except at ihe poini 

 where they are yellow. while the lip has also but one dull olive brown spot occu- 

 pying ihe cenire of ihe base. 



Capt. Sutlon R. N. brought many valuable planis lo England from America. 



Pseudobulbs 1— I'A" high, flower stems few flowered, usually shorter, than the 

 leaves and drooping. Occasionaliy the spike is longer, and a little branched, bui this 

 is very rare. Bateman.

 chocolate-brown stains on ihe flowers. anoiiier wiih brown flecks on a green ground, 

 and a third of one dull olivc-brown lint. In all of them the lip is snow-white when 

 flrst open. becoming yellowish afterwards. Bul I have seen with Sir Philip Egerton 

 a flower just opeiied, the lip of which was perfectly yellow ; the oiber flowers having 

 while lips as usual. According to Mr. Skinner, tlie summer temperature of the 

 country where ihis species grows wild is betweeu 55° and 70°; he adds thai in De-
