P. (Grandifoli^) ADIAXTOIDES, vars. — Yungas, alt 6,000 

 ped., Unduavi, alt. 8,000 ped. (Nos. 3,010, 3,012, 3,013, 3,015, 

 3,016,3,021,3,047 pro parte). — Some of these forms, notably Nos. 

 3,012, 3,013 and 3,021, approach the West Indian '' P, siiperbaj' 

 but are hardly separable from typical P. adiantoides ; and the 

 '*/*. superba'' gathered by d* Orbigny '* in Boliviae locis udis 

 silv^arum inter Chupe et Yanacache " doubtless belongs to the 

 same category. The original P. superba^ founded by Nees on a 

 plant gathered in the Mauritius by Sieber, however, seems dis- 

 tinct. 



P. NoTARlSir, Mitt. Yungas, alt. 4,000 ped. (Nos. 3,009, 

 3,011, 3,014). Cum forma ^equatorial! archetypa convenit foliis 

 praelatis, semicordato-triangularibus, paucidentatis, necnon per- 

 ianthiis immersis late alatis, &c.; solum dififert foliis paulo longi- 

 oribus obtusioribusque.

 denticulatis, dentibus sub 70. Mapiri, 5,000 ped. No. 3,019. 

 The three forms described in Hep. Am. et A., distinguished 

 namely by differences in the breadth of the leaves and in the 

 degree of marginal dentation, belong to but one species. The 

 toothing of the anterior margin is variable but never entirely 



disappears (as asserted by Lindberg). The presence or absence 

 of a wing to the perianth is inconstant in all the forms.
