Posoqueria panamensis (Walp. & Duchass.) Walp., Ann. Bot. Syst. 2: 797. 1852.

Stannia metensis Karst., Linnaea 28 : 441. 1S57.

Tocoyena mutisii H.B.K.. Nov. Gen. & Sp. 3: 411. 1819.

Type. "Isthmo Panamensi."

Although I have not seen the type specimen of Stannia metensis Karst, (from Rio Meta, Colombia), Karsten’s description of the corolla-tube as “quadripolli-cari’ places it more nearly within the size measurements of material collected from Panama and Central America. For this reason, I have considered S. metensis synonymous with S. panamensis Walp. & Duchass. rather than with S. grandiflora Karst., in which the corolla is stated to be ‘‘decimetra dua longo" and 1O Zoll lange Rohr” (FI. Columb. 1: 31, t. 16. 1859).
