508 ONAGRACEJE. CEnothera. 



California, Doiarlas! — A very distinct small species; the leaves 1-2 

 inches long and scarcely a line in breadth ; the flowers large for the size of the 

 plant (about 10 lines in diameter when expanded). From'the appearance 

 of the ovary, we suspect the capsule is somewhat 4-winged, or perhaps 

 4-grooved. 



§ 9. Stigma capitate : tube of the calyx ohconic or infunclihuliform, usually 

 much shorter than the ovary : petals ohovate, entire or emarginate : stamens 

 erect ; the alternate filaments mostly shorter : anthers linear-ohlong or 

 roundish : ca2)sules subulate, oblong or linear, mostly sessile, membrana- 

 ceous, often curved or contorted; the dissejnmoits thin and often evanescent : 

 seeds ascending, in a single series, oval or oblong, ivith a membranous 

 testa : caulescent : floioers diurnal. — Sph^rostigma, Seringe. (Holo- 

 stigma, Spach.) 



* Mostly annual : floioers {mostly rather large) axillary, yellow turning to 

 hluish-green in fading : tube of the calyx infundibuliform or obconic, shorter 

 than the segments : stamens unequal, shorter than the petals : anthers short, 

 or often oblong-linear and fixed near the tniddle : capsules acutely quadran. 

 gular, attenuate at the apex, usually curved or spirally contorted lohen 

 mature. 



50. CE. viridcsccns (Hook.) : sufFruticose, densely tonientose-canescent ; 

 stems much branched from tlie base, ascending ; leaves ovate or oblong, en- 

 tire or slightly serrulate (" coarsely toothed," Hook.), sessile; flowers large; 

 tube of the calyx -much shorter than the segments ; petals cuneiform-obovate, 

 very broad, emarginate (golden yellow with a brownish spot at the base), 

 twice the length of the slightly unequal stamens ; anthers oblong-linear, fixed 

 near the middle ; style longer than the stamens ; capsules hairy, acutely 

 quadrangular, recurved, rather acute. — Hook. fl. Bor.-Am. 1. p. 214.

California, on the sandy beach near St. Diego, Nuttall! N. W. Coast (ac- 

 cording to Hooker, but probably California), Menzies. April-May. — " Ap- 

 parently a perennial, with large and showy flowers about the size of those of 

 ffi. biennis; the plants spreading out so as to make a wide silvery carpet. 

 Leaves about half an inch long, acute or obtuse. Seeds numerous, small, 

 ovate-oblong, acute at the base." Nutt. — Our description is wholly drawn 

 from Mr. Nuttall's plant, which Hooker (hot. Beechey's voy. suppl. 2}' ^-^l-) 

 pronounces to be identical with ffi. viridescens, although we should have not 

 supposed it from the description, which was doubtless made from imperfect 

 materials. We see no approach to coarsely serrate leaves. The base of the 

 stem is decidedly shioibby. 



51. CE. historta (Nutt. ! mss.) : somewhat hirsute ; stems decumbent, 

 much branched from the base ; radical leaves spatulate-linear, petioled ; 

 cauline ones lanceolate, mostly sessile, acute or acuminate, sharjjly denticu- 

 late ; flowers (rather large) axillary ; tube of the calyx infundibuliform, 

 rather shorter than the segments ; petals broadly obovate, entire, more than 

 twice the length of the longer stamens ; anthers oblong, fixed near the 

 middle ; style longer than the stamens ; stigma large and thick ; capsules 

 acutely quadrangular, attenuate at the summit, somewhat pubescent or 

 hirsute, spirally contorted or coiled. — ffi. heterophylla, iYwii. .' «!S5., not of
