The name P. bigoriensis had been applied (as bigorriensis] 

 to another species prior to Rossmaessler's use of it; biger- 

 rensis Moq. was not stated to be an emendation, it was a sub- 

 stitute; and as such it is sufficiently distinct to be retained. 

 The names substituted by Locard and Fagot are superfluous. 

 Some authors allow the form specific rank.
