BOTANY. 
9. S. POLYGALOiDES, Gray. Proc, Amer. Acad. 6. 519. Auuual f, pauioulately branched ; racemes 
spikelike; calyx yellow, about equaling the purplish petals, 2-3" long, the outer sepals eubcordate- 
roimded, the inner oblong-lanceolate, acuminate; siliques very narrowly linear, long, |" wide, 
straight or nearly so, reflexed, pointed with the short style; seeds narrowly margined.— California. 
"Rather to be distinguished as of a separate section." 
* * More or less bristly or hirsute with simple hairs, 
(a.) Cauline leaves or some of them usually auriculate- or sagittate-clasping and laciniate-toothed ; 
flowers, at least the calyx, crimson-purple or red. 
10. S. GXANDUXosrs, Hook. Cauline leaves narrowly lanceolate and mostly sagittate-clasping, their 
sparse teeth with callous rather than with glandular tips ; racemes lax, the pedicels and flowers glab- 
rous or nearly so ; calyx ovate ; siliques narrowly linear, 2-3' long and less than 1" wide, straight or 
curved, ascending ; immature seeds slightly margined.— California. 
11. S. HETEROPHYLLU8, Nutt. Annual or biennial, 3-5° high, branching, glabrous at top ; leaves 
laciuiate-pinnatifid, cauline ones sagittate at the base and clasping ; flowers pendulous, purple ; sepals 
deep-purple, glabrous, long, connivent ; petals linear, undulated, purple and whitish ; siliques very long 
(3-5') and narrow, pendulous on pedicels i" long; stigma emarginate; seeds slightly margined.— St. 
Diego, California, (Nuttall.) The plants of Coulter and Xautus, referred here, are Cmlantlm CouJterL 
12. S. HispiDus, Gray. Annual, 2-3' high, hispid throughout ; leaves cuneate or obovate-oblong, 
coarsely toothed or incised, the cauline sessile, hardly at all clasping,- raceme short, loosely flowered; 
pedicels spreading or at length recurved; siliques linear, 1^' long, 1" wide, compressed, erect; stigma 
emargmate, nearly sessile ; seeds winged.— California. 
(J.) Cauline leaves not clasping nor auriculate at base, entire, the lower sinuate-pinnatifld with 
glandular teeth and contracted into a margined petiole ; flowers yellow. 
13. S. FiAVESCEXs, Hook. Pilose ; leaves hnear-oblong ; flowers erect ; petals Imear, acute ; sepals 
ovate, obtuse, the petals nearly twice longer; anthers purplish, linear-oblong, filaments free; stigma 
capitate; siliques erect, hirsiite, pointed with the short style. About 1° high, simple, erect; radical 
leaves nearly 2' long, the cauline scarcely 1' in length.-California. Prof. Brewer's plant, referred to this 
species, is Caulanilms procerus. 
Doubtful species. 
14. S. EEPAXDTTS, Nutt. "Hirsute, particularly the lower part; leaves oblong-lanceolate, elongated, 
clasping, angularly toothed or repand above ; flowers white ; petals about as long as the calyx. Stem 
simple, about 2° high; pedicels shorter than the calyx; sepals and petals linear."— St. Barbara, Califor- 
nia, (Nuttall.) Only known from Nuttall's description. 
SILENE^. 
In the distribution of the plants in the collection belonging to this tribe of the Caryophyllaeeie the 
usual arraiigement of the genera has been observed, as retained by Bentham & Hooker and as on the 
whole probably the most satisfactory. Dr. Paul Eohrback in his Monograph of the Genus Silene C" Mn

In his distribiition, all of our native North American species fall into his genera Melandryum, Silene and
