In brackish marshes, San Francisco, Cal., H % 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, finely 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 /. 
effusus and J. Paeificus , 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
