forms of a single variable species. The difference said to be shown 

 ^in the stipe-scar I have not been able to make out. 



In a series of collections made in 1898 no Wolffiellas could be 

 found till early in July, when a few specimens of W. lingulata were 

 detected, but none of the other species. August 15th W. lingulata 

 had increased in quantity, but was still scarce, and a few doubtful 

 specimens of W. oblonga could be separated. On September 17th 

 there was an abundance of W. oblonga, and it was not difficult to find 

 good typical fronds of W. lingulata. On November 19th, when the 

 next and last examination was made, the Wolffiellas had mostly 

 disappeared, many fronds were dead, and of those living more than 

 half belonged to W. oblonga. 



1^ Atriplex Breweri, Watson, Proc. Am. Acad. ix. 119. A. 

 orbicularis, Watson, 1. c, xvii. 377. On the bluffs of the seashore. 

 San Juan, Alderson. Santa Monica, Hasse, Parish. 



Santa Monica is the type locality of A. orbicularis and in part of 

 A. Breweri. The first is monoecious, while the second was charac- 

 terized as "mostly dioecious." It is certainly sometimes monoe- 

 cious, and probably mostly so. In one of Dr. Hasse's specimens 

 the inflorescence is of short axillary panicles, leafy, or naked, the lower 

 panicles made up of spikelets of all staminate flowers, and the upper 

 panicles of spikelets pistillate at base and staminate above. These 

 latter exactly represent A. orbicularis, so that if the specimen were 

 broken in half, the upper portion would agree with the character of 

 that species, while the lower half would answer for a staminate 

 specimen of A. Breweri. In hnbit, leaves, and bracts there is no 

 difference between the two supposed species. 



Salicornia herbacea, Linn. Sp. PI, Ed. 2, 5. Coast of San 

 Diego County, near the Boundary Monument, Nov. 1898, Bravdegee. 

 A plant of low growth and compact habit, but in other respects 

 possessing the characteristics of this species. I am not aware,, that 

 this and the following species have been collected heretofore in 

 California.
