Anoiher form, extren#ly like tliat of panchrysum , hut wiih the column-wings of 

 auriferum. Than ihe latter ihe flowers are largor, the sepals and petals lanceolate 

 acuminate, not linear and obtuse wilh a point, and ihe crest has ihree deep wavy 

 keels, each lerminating in front in a strong upright tooth. Two other teelh of the 

 same form and size rise in front of these, and ahout four emarginate waris form a 

 curve on each side.

0. Skinneri Lindl. in Gard. Chron. 1855. p. 629. 

 Wild in Peru; on walls and rocks in and about Loxa-Hartweg. 

 A very siout species, with leaves len to fifteen inches long and two broad, and a 

 stiff p\ramidal panicle iwo feet bigh and a foot wide. The plant I have called 0. 

 Skinneri should, I ihink, upon final consideration, be regarded as a variety, wilh close 

 prcssed bracts, and an apiculate lip. The other ;differences which where supposed 

 10 exist are probably referable to ihe difTerent condiiion of the dried and recent spe- 

 cimens. It is a very flne plant. The branches of the panicle are covered by a most 

 delicaie bloom. The flowers, as large as the largesl form of 0. ampliaium, are a 

 brilliant golden yellow with about three cinnamon blotches at the base of each di- 

 vision, and a siain of the same colour across ihe lip imraediately below the crest and 

 at the base of each division, and a stain of ihe same colour across ihe lip imme- 

 diately below ihe crest and at the base of its side lobes. The numerous sinuosities 

 of the crest are white.
