1. S. arvensifl, Limi. Smootli ; stoins sevoml, a foot or two lii>,'li : lenvcs fili- 

 form, miineroua in apparnnt whorls, 1 or 2 iiiclics long; stipules small: jlowerg 

 white, the long jiodiccls at length roflexed : sepals oblong to ovate, 2 or 3 linca 

 long, equalling the petals, a little shorter than the broadly ovoid capsule : seeds 

 rough, acutely margined. 



Sparingly naturalized ; near San Francisco {Torrcy) ; Mark West Creek, Bolandcr. 



7. LEPIGONUM, Fries. Sand-Spurkey. 

 Sepals 5. Petals 5, entire, rarely fewer or none. Stamens 10, or fewer by abor- 

 tion. Ovary 1 -celled, many-ovuled : styles^ 3, or rarely 5. Capsule 3-valved. 

 Seeds winged or naked : embryo annular. — Low herbs, usually diffuse ; with seta- 

 ceous or linear fascicled leaves and scarious stipules ; flowers white or pink, pedi- 

 celled, in at length snbracemose cymes. — Kindberg, Monog. Lepig. 



A genus (known also as Spergidaria) of 5 or 6 sjjecies, chiefly confined to the sea-coast or saline 

 localities ; widely distributed through the temperate zones. Species of rather difficult definition. 



1. L. macrothecmn, Fischer <t Meyer. Poronnial, rather stout, often a foot 

 high, decumbent at base, glabrous below, pubescent above, the calyx more or less 

 tomeutose : leaves llesliy, | to 2 inches long, with large ovate stipules : flowers 

 large, subracemose ; pedicels 4 to 12 lines long, becoming reflexed : sepals 3 lines 

 lung or more, equalling or exceeding the petals : capsule ovoid, a little exceeding 

 the calyx: ^eeds smooth, narrowly winged. — Kindberg, 1. c. 16, t. 1, fig. 1. Sper- 

 gnlaria rubra, Torr. in Pacif. R. Rep. iv. 70. 



In salt-nmrslies from Marin County to San Diego. 



2. L. medium, Fries. More slender and diffusely branched than the last, an- 

 nual or biennial (sometimes perennial 1), more or less pubescent or often nearly 

 glabrous : leaves fleshy, \ to 1 inch long or more ; stipules short : pedicels ^ to 6 

 lines long, often short, reflexed: flowers smaller; calyx 1 to 2 lines long: seeds 

 smaller, smootli, wingless or narrowly winged. 



In saline localities from San Diego to Pnget Sound and across the continent ; also European 

 and Asiatic. A very variable species as at present received. 



8. POLYCARPON, Linn. 



Sepals entire, scarious upon the margin. Petals small, hyaline. Stamens 3 to f>. 

 Ovary 1 -celled : style short, 3-cleft. Capsule 3-vaIved, several-seeded. — Low dif- 

 fuse dichotomously branched annuals ; leaves flat ; stipules small, scarious ; flowers 

 small, cymose. 



Half a dozen species, in the temperate and warmer regions of both hemisphere-s. 



1. P. depressum, Nutt. Very small and murli bninclied, srarrely an inch 

 high, sli'iitliT and glabrous : leaves narrowly spatulate, in pairs ; stipules small and 

 narrow : flowers minute, in loose cymes, the pedicels with small bracts : petals nar- 

 row, much shorter than the sepals, entire: capsule globose, 6-12-seeded. — Torr. 

 & Gray, Fl. i. 174. 



On bare sandhills near San Diego {Nuttall) ; near San Bemanlino, /yfmmon. 



P. TETRAPHYU.UM, Linn, f., is found oround the world, but is not yet known from California. 

 It is a larger plant in every way, the broad leaves sometimes apparently in lours, and the stipules 

 and imxcls often conspicuous. 



9. LGGFLINGIA, Linn. 



Sepals .'), rigid and rnrinate, the margin .'^rarious ; the tliree outer with a narrow 

 tooth upon each side. TVtals very small or none. Stamen'; 3 to .'>. Ovary l-celled:
