This appears to be the species described h\ Hillebrand" under the name 

 E. mexicana Link, the chief cited specimen of which, from Lanai, has been kindly 

 lent to me by Dr. Diels. Director of the Botanic Garden at Berhn. The panicle is 

 much smaller and less d \elo])ed than that of the specimen in the dray Herbarium. 

 Hillebrand cites also a ;;econd specimen "Collected also by the U. S. E. Exped." 

 which evidently is the sa ne collection as the one here made the type of E. mauicnsis. 

 The Gray Herbarium specimen was examined by Munro and is labeled by him 

 "Eragrostis mcxicaiic? Link. E. cacnilca Hillebrand mss." "E. cocnilcsccns. 

 Hbd. in herb." is given bv Ilillebrand as a svnonym of E.. iiicxicaiia. This si)eci- 

 men is not referable to the annual E. incxicaua.
