Potyffoneai.] CALIFORNIA. 157 



The above character, taken from the specimen before us, shows the slight differences between it and the 

 plant found by Chamisso, its original discoverer. 



2. Plantago major. Linn. 

 Specimen in a very poor state. 



Ord. XXXVIII. NYCTAGINE^l. Juss. 



1. Abronia umbellata; foliis oblongis glabris, involucro persistente 5-6-phyllo multifloro, 

 perianthii (rosei) tubo elongato limbo laciniis bilobis, staminibus inaequalibus inclusis. — 

 Lam. III. t. 105. — Hook. Exot. Fl. t. 194.— Tricratus admirablis. L'Herit. — Willd. — Spr. 



The figure in the Exotic Flora does not represent the two-Iobed segments of the limb of the perianth. 

 Two other species are found along with this in the sands of the sea-shore in California, both of which, 

 however, have yellowish flowers : the one is A. latifolia, Eschsch. ; foliis latis subovatis obtusis basi acutis, 

 involucro 2-3-phyllo paucifloro. — The other is A. arenaria, Mew. ; foliis late cordatis, involucro 5-phyllo 

 multifloro, perianthii limbi laciniis rotundatis undulatis. All the three have glabrous leaves, a persistent 

 involucre, an elongated tube to the perianth, and the stamens unequal in length, and included within its 

 tube : by which they form a distinct section from A. parviflora, H. B. K., where the involucre is deciduous, 

 the tube of the perianth short, the stamens equal in length, and exserted. It is to be regretted, that Esch- 

 scholtz has not given more detailed characters of his A. latifolia; for with the exception of the colour of the 

 flowers, there being few within the involucre, and the greater breadth of the leaves, which, however, he 

 states to be extremely variable in shape, there is scarcely enough to separate it from A. umbellata. 



Ord. XXXIX. AMARANTHACEiE. Juss. 



1. Amaranthus hybridus; foliis ovato-lanceolatis, glomerulus interrupte spicatis, spicis 

 decompositis congestis axillaribus terminalibusque erectis, perianthii laciniis lanceolato- 

 subulatis, staminibus quinque. — Linn. — Pursh, Fl. Am. v. 1. p. 207. 



Ord. XL. CHENOPODIEiE. De Cand. 



1. Atriplex arenaria. Nutt. 



Folia alterna, oblongo-elliptica, subsessilia integerrima, obtusa, obsolete trinervia, utrinque albido-fur- 

 furacea ; non nitida. Spicat breves, axillares. Cuulis decumbens, herbaceus, ramosus, angulatus, furfuraceus. 



Apparently allied to A. Sibirica, L. ; but we have not seen the fruit. It agrees with original specimens 

 of Mr. Nuttall's A. arenaria in our Herbaria. 



2. Atriplex angustifolia. Sm. 



1. Chenopodium murale. Linn.? 



2. Chenopodium ficifolium. Sm.? 



3. Chenopodium ambrosioides. Linn.? 



These three species of Chenopodium seem to correspond with the Europaean species of the same name. 



Ord. XLI. POLYGONEiE. Juss. 



1. Rumex salicifolius ; ramis decumbentibus, foliis lanceolatis integerrimis subundulatis, 

 glomerulis spicatis subaphyllis, floribus monoicis, sepalis internis demum aequalibus oblongis 

 obtusis integerrimis unico (quandoque duobus) valde granulifero. — Weinmann, in Bot. Zeit. 

 v. 4. p. 28.
