Hab. Puget Sound and Gray's Harbor, Washington Territory; also 

 around the Bay of San Francisco, and along the coast of California. — 

 Our plant agrees very well with the figure and description of De 

 Candolle (1. c), and also with a Chilian specimen of P. ramosissima, 

 received from Sir William Hooker, except that the stipules are larger 

 and more silvery in the former. Mr. Nuttall was inclined to regard 

 it as a distinct species. P. polycnemoides, Walp. (1. c), is probably 

 not distinct from P. ramosissima. 



10. SPERGULARIA, Pers. 



I. Spergclaria rubra, Pers. 



Hab. Puget Sound, and saline places on the Lower Sacramento, 

 California. — We find both margined and immarginate seeds in the 

 same specimen, as has been noticed before in this variable (and prob- 

 ably composite) species. Some of the Californian specimens seem to 

 be decidedly perennial, with an almost woody base. 



II. M L L U G 0, Linn. 



1. MOLLUGO VERTICILLATA, Linn. 



Hab. Banks of the Columbia and Upper Sacramento Rivers. — 

 This plant, which in the Atlantic States, has every appearance of 

 having immigrated from the south, probably from the Antilles, is rare 

 on the Pacific side, where it may be indigenous. We have received it 

 from thence only in the collections of the Exploring Expedition.
