NEW SPECIES OF PACIFIC COAST PLANTS. 33 
Collected in the Umpqua Valley near Roseburg, Oregon, 
May 2, 1887. Much like L. Virginicum but easily distin- 
guished by the four stamens and the larger flowers. 
Arabis secunda. Stems several, erect, simple above the 
apparently perennial, woody, branching base, 10 to 18 inches 
high, stellate pubescent; lower leaves lanceolate about an 
inch long, narrowed below to a winged petiole, entire, acute; 
cauline leaves linear, revolute, sessile, distinctly auricled, one- 
half to an inch long: raceme many-flowered, strictly secund, 
pedicels filiform, 2 to 3 lines long (all deflexed one way): 
style very short; pods 1 to 2 inches long, less than a line 
wide; seeds small, slightly winged. 
Collected on Mount Adams, Washington, August, 1882. 
Somewhat like A. Holbcellii but distinguished by its very 
narrow pods in a secund raceme. 
Cardamine quercetorum. Glabrous, stem 6 to 12 inches 
high (from a branching tuberous root: radical leaf 3 to 5- 
foliolate, leaflets ovate to elliptical, coarsely dentate, 1 to 2 
inches long, petiolate; cauline leaves 1 to 4, mostly 3 to 5- 
lobed or-parted, with oblong-lanceolate, acute, mostly entire, 
divisions: racemes densely many-flowered; corolla rose- 
purple, a half inch long: fruit not seen. 
Collected in the Williamette Valley near Silverton, Oregon, 
growing under small oaks, etc. 
Luprnus LAxrrLorus, Dougl., var. montanus. Leaflets 
silky on both sides, rather shorter than the type; calyx 
densely silky, narrowed downwards, prominently spurred. 
Collected on Mount Hood. Perhaps this will be made a 
distinct species when some one who knows our Lupines 
works out a revision of the genus. 
Mitella Hallii. Pubescent with long whitish hairs, 
scapes naked, 6 to 18 inches high: leaves all radical, oblong, 
cordate, obscurely 5 to 7-lobed, repandly toothed, 6 to 18 
lines long on rather stout petioles: flowers numerous, on 
short erect pedicels, often 2 or 3 together, therefore some- 
what paniculate; petals yellow, pinnate with 2 to 4 short
