*Deberibed as L. Hassei in Pitt. i, 135. 
A single large clump which grows 
_in the village of Avalon appears to be the only one known in California. Be- 
low San Quintin it is common, and grows equally as large. On Santa Cata- 
lina it was first collected by Dr. H. E. Hasse and afterwards by Mrs. Wheeler. 
iThis and one or two other grasses were determined by Dr. George Vasey.
