MISCELLANEOUS SPECIES. 63 
Common in fields about Antioch on the lower Sacramento, 
California, collected by the writer, April 17, 1887. 
The plants were out of flower, nearly, but the stamens and 
petals are very much as in T. lasiophyllum, apparently, and 
the two are nearly related; but this plant has a peculiar 
habit, and its stiff sharp spreading and often slightly curved 
pods are in appearance more like thorns than siliques. 
SILENE SIMULANS. Inflorescence viscid-puberulent, the 
herbage otherwise glabrous and dark green: stems a foot or 
two high, decumbent, from a thick fusiform perpendicular 
root: leaves narrowly linear-lanceolate, 2—3 inches long, the 
internodes short on the lower part of the stem and the axils 
bearing ovate scaly-bracted bulblets : flowers somewhat nod- 
ding, in a cymose panicle, deep scarlet: petals deeply 4-cleft, 
the upper two at a right angle with the calyx, the other three 
parallel with it, appendages erose: stamens declined : seeds 
strongly tuberculate on the back. 
Islands of Santa Cruz and San Miguel, off the coast of Cali- 
fornia, collected by the writer in August and September, 1886. 
A beautiful species, near S. laciniata, the flowers rather 
smaller and marked by the irregularity which characterizes, 
and may be taken as imitative of, those of the Zauschnerias 
with which it grows, for an account of which see page 25 pre- 
ceding. 
LEPIGONUM TENUE. Annual, slender but diffusely branch- 
ing, forming depressed mats a foot broad, without viscosity or 
evident pubescence : leaves narrowly linear, an inch long: 
Stipules inconspicuous, very short, often broader than long: 
flowers minute, innumerable, cymosely crowded on all but the 
lower parts of the branches, subsessile, or the earlier ones on 
pedicels of a line or two long : sepals obtuse, less than a line 
long, at first scarcely more than a half line: petals wanting : 
stamens 2 only: styles 3: capsule triquetrous, more than 
twiee as long as the calyx: seeds numerous, minute, reddish
