Subäquatoriale andine Provinz. Columbien, ohne genaueren Standort (Carder 

 n. 134!). Zuerst gefunden von Seilor ßaldeviama. — Am Salto de Tequendama, 

 Provinz Bogota (Wilke!). 



Nota \. Differt floribus etiam majoribus quam illis G. superbientis, cristae fabrica, se- 

 palis laterabbus multo longius unguiculatis quam dorsale ab omnibus affmibus. Est ceterum 

 G. superbienti affine. 



Nota 2. De orthographia nominis specifici magna est confusio. In herbario suo Reichen- 

 bachius scripsit »Baldawamae«; in diagnosi sua 1. supra c. » Baldewianae« ibique nomen col- 

 lectoris et bujus speciei et G. tetracopidis Reichb. f. semper Senor ßaldeviama scribere solitus est.
