peculiar green of its foliage and by the circumstance that it fruits early

 growing sessile, one on each side of the stem. It was found in the fol- 

 lowing localities: 



CALIFORNIA. 



Beep Spring Valley. — Occurs in company with Grayia, Eurotia, Balea, 

 Lyeium, and Tetradymia spinosa; altitude about 1,080 meters (5,500 

 feet). 



NEVADA. 



Fish Lalce Valley. — Common on the upper levels, ranging up on the

 tude of 1,190 meters (3,900 feet) ; on the west side of the valley (Pah- 

 ranagat Mountain slope) it ranges up to 1,525 meters (5,000 feet). 

 It was heavily laden with fruit May 22-26. 



Charleston Mountains. — On the west slope of the Charleston Moun- 

 tains Menodora spinosa ranges from about l,525meters (5,000 feet) doAvn 

 to the upper levels of Pahrump Valley.

 (3,800 feet). 



Fraxinus coriacea. 



This ash was observed in the following localities : 



CALIFORNIA. 



Owens Valley. — Common in open groves along Cottonwood and Ash 

 creeks on the west side of Owens Lake, where it was heavily laden with 

 fruit June 19. Another and very distinct species occurs in company 

 with F. coriacea and was in fruit on the same date. 



NEVADA. 



Ash Meadoivs. — Ash Meadows takes its name from the circumstance 

 that this small ash is common about many of the warm springs. Ash
