GRASSES IN THE BERNHARDI HERBARIUM. 37 
Podosaemum distichophyllum is not the Muhlenbergia 
distichophylla of all recent collections, but Muhlenbergia 
grandis Vasey; which name, of course, now becomes a 
synonym. 
These are a few of the points which this valuable collec- 
tion has enabled us to settle and I only regret that we are 
unable to examine the entire collection. 
Acrostis carspitosaA J. S. Presl in C. B. Presl Reliq.

Auorreropsis pistacuyA J. S. Presl in C. B. Presl Rel. 
Haenk. 1:344. tab. 47. ‘*Hab. ad Monte-Rey in

The locality cited by Presl is doubtless an error. The 
ticket. on the specimen in the Bernhardi herbarium indi- 
cates that it was collectedin Luzon. In one of the spike-
