Nota 1. Species satis peculiaris et nulli proprie affmis. Gl. Veitch plantam laudat et 

 llorum ditissimam esse declarat, comparat flores cum illis Odontoglossi blandi Reichb. f., cl. 

 Williams cum illis Odontoglossi naevii Lindl. magnitudine valde reductis. 



Nota 2. Haec species G. nigratum et antecedentes in figura septima delineatae pro gyno- 

 stemii fabrica etiam Oncidiis genuinis sectionis Heteranthorum adscnbi possint, si non label- 

 lorum circumferentia et tuberculis discrepent.

A long struggling species with the aspect of a small-lipped Oncid, but the column 

 is clavate and distinctly united with the base of the lip. When very young the lip 

 has 3 central ridges which touch each other and a pair of tubercles on each side, when 

 the flower is füll grown each pair of tubercles has become a rib and the middle ribs 

 have separated from each other by a considerable interval. 



Nota. Praetuli verba magistri verbotenus referre, cum notulas e specimine Lindleyana 

 scriptas amiserim, quod gravissime fero. Ex icone Lindleyana quam praesto habeo et diagnosi 

 originaria facile intellegendum est, speciem esse Cyrtoehilis genuinis valde affinem. Ambitus 

 labelli ejusque curvatura omnino quadrant cum Cyrtoehilis, differt solummodo crista 5-seriata.
