Discussion:

Peridium bicolor var nitidum Benth., Jour. Bot. & Kew Misc. 6: 323. 1854.

Pera decipiens Miill.-Arg., Linnaea 34 : 201. 1865 quoad Rich. Schomb. 1070 and 1071.

Type. There are 5 specimens cited by Bentham in the original description, which have to be considered syntypes: British Guiana, Rob. Schomburgk second collection 685 and 686, Rich. Schomburgk 1070 and 1071; and Obidos on the Rio Negro, Spruce. Although I have not seen these syntypes, Bentham’s description is clear and to the point: “foliis...subtus... squamellis minutis...flavi-cantibus et glandulis minutis punctatis.”
