seminibus ovatis obtusis brevissime apiculatis. — Northern 
Europe. 
Var. 3. littoralis ; sepalis ut in Europzo capsulam angusti- 
orem acutius angulatam longius mucronatam zequantibus ; 
antheris majoribus filamento brevissimo quadruplo longiori- 
bus ; seminibus ut in Kuropzo.—Atlantic coast to the upper 
Mississippi. 
Var. y. montanus: sepalis fere equilongis xqualibus seu 
interioribus obtusioribus; antheris ut in littorali; capsula 
ovato-pyramidata angulata rostrata; seminibus minoribus 
angustioribus longius apiculatis—Western plains and moun- 
tains. 
Sub-sp. J. Pacificus: caulibus crassioribus mollioribus 
seepe fistulosis; panicule densiflore ramis secundis; floribus 
majoribus; sepalis exterioribus acutissimis interiora obtusa 
paulo superantibus capsulam ovatam acutam mucronatam 
subequantibus ; antheris majoribus filamento brevissimo quad- 
ruplo quintuplo longioribus; seminibus magnis ovatis obtusis., 
breviter seu vix apiculatis tenuissime irregulariter reticulatis 
seu levisculis.—J. Lesweurti, Bolander in Proc. Ac. Calif. 2,

culmo erecto elato (tripedali) tereti striato farcto basi vaginis 
atrofuscis obtusis breviter aristatis stipato; spatha paniculam 
decompositam densifloram multiradiatam corymbiformem 
longe superante ; sepalis «quilongis lanceolatis, exterioribus 
acutato-subulatis, interioribus obtusis mucronatis capsulam 
ovatam subacutam trilocularem equantibus; staminibus 3 
sepalis quarto parte brevioribus, antheris linearibus filamento

In brackish marshes, San Francisco, Cal., /Z, Bolander—In 
its technical character, especially in the form of the sepals and 
the capsule, this plant corresponds well with Meyer’s Chilian 
species, but a specimen in the royal herbarium at Berlin, 
brought from Chili by D’Urville, has much smaller flowers, a 
more compound, loose-flowered panicle; smaller flowers, and 
smaller, narrow, long apiculate, tinely lineolate seeds, and is 
in all respects similar to J. effusus, with the exception of the 
inner sepals and the capsule. But unwilling to give a new 
name to a plant so incompletely known, I provisionally refer 
this Californian to the Chilian species ; I suggest, however, the 
possibility of the Californian plant being a hybrid between J. 
effusus and J. Pacificus, which both occur in its neighbor- 
hood; it seems that only very few and imperfect seeds can 
be found in the otherwise well developed specimens now
