In brackish marshes, San Francisco, Cal., IL 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. eft'usas, 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. 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
