ORCHIDACE^ 



lively broader in comparison with their length and in possessing 

 very short petioles. The roots are produced in pairs on the rhi- 

 zome near the point of origin of the secondary stems. 



In my herbarium there is a single specimen of P. repens com- 

 municated by John Donnell Smith, which constitutes the type 

 of the species. This specimen was collected at Cubilquitz, De- 

 partment of Alta Verapaz, Guatemala, at an altitude of three 

 hundred and fifty metres, by H. von Tuerckheim. The label 

 bears two numbers, namely, 8305, which apparently designates 

 the number under which J. D. Smith distributed his specimens, 

 and 496, which is probably the field-number used by von Tuerck- 

 heim. 



In his Enumeratio Plantarum Guatemalensium, unfortu- 

 nately. Smith has used my name Pleurothallis Mans to distin- 

 guish this species. P. Mans is a homonym. This fact was discov- 

 ered too late for correction in Smith's Enumeratio.
