qua, Nutt. Glabrous, usually erect, diffusely branched 3-12 inches high 
from an annual root: leaves narrowly oblong or oblanceolate pinnatifid 
with oblong usually toothed lobes, rarely only sinuate toothed: flowers 
yellow in rather dense racemes: petals.a little exceeding the sepals: pods 
rather slender, 4-8 lines long, about equaling the pedicels, often curved. 
On rich, alluvial river bottoms, British Columbia to Lower California. 
R. lyrata Greene Man. 20. Nasturtium lyratum Nutt. Stems erect or 
decumbent, commonly diffusely branched from the base: leaves lyrate or 
pinnatifid, the segments oblong-lanceolate, incisely serrate or angularly 
toothed: pods linear, compressed, 8-10 lines long, more than twice the 
length of the pedicel, slightly curved, obtuse, tipped with the very short 
style. On muddy banks and in wet places, Oregon and northern Cali- 
ornia. 
R. polymorpha. Nasturtium polymorphum Nutt. T. & G.i, 74. Stems 
6-10 inches. high from an annual or biennial root: leaves rather narrow, 
deeply pinnatifid or almost entire, the segments entire, short, linear 
acute: flowers:small; the petals scarcely longer than the calyx: pods ob- 
long-linear compressed: stigma minute, nearly sessile. ‘‘Banks of the Ore- 
gon, Nutt.’? Moist places. Willamette and lower Columbia valleys. 
_R. tenerrima Greene Eryth. iii, 46. Glabrous: stems weak and de- 
cumbent sparingly branched 6-10 inches long from an annual root: leaves 
few lyrately pinnatifid, the terminal lobe acutish, rachis of the few ra- 
cemes almost capillary: pods subconical to ovate-laaceolate slightly 
curved, the apex surmounted by a considerable beak-like style: valves and 
partition both very thin: seeds many in 2 rows under each valve. On 
moist banks, eastern California and western Nevada to Washington and 
Wyoming.

Glabrous erect branching biennial or perennial herbs with an- 
gled stems and entire or pinnatifid leaves. Sepals oblong, often 
colored: the lateral pair often saccate at base and slightly con- 
nate on the back near the apex. Petalsspatulate or with obovate 
blade and slender claws. Stamens 6, free and unappendaged, dis- 
tinctly tetradynamous. Style short: stigma bifid. Pods linear, 
elongated, somewhat 4-angled. Seeds in one row in each cell. 
Cotyledons slightly oblique. 
B. vulgaris R. Br.I.c. Stems erect, 1-3 feet high, simple or corym- 
bosely branched, somewhat angled: radical and lower caudate leaves usu- 
ally pinnately parted, the terminal lobe ovate or orbicular, rounded at.the 
apex and varying from cuneate to cordate at base, entire or with a few 
rounded teeth or lobes; lateral segments very variable usually oblong, en- 
tire or toothed: petioles auriculate at base: upper leaves entire or toothed, 
clasping at base: flowers ina short dense oblong raceme, bright yellow: 
petals nearly or quite twice as long as the sepals: pods ascending or sub- 
erect upon more or less spreading pedicels. Common along streams and in 
cultivated fields. Lower California to Alaska and across the continent. 
B. stricta Andrz. Bess. Enum. 72. Stems erect 1-2 feet high, leaves 
-yrately pinnatifid with a large rounded terminal lobe and 1-5 pairs of lat- 
eral ones: flowers pale yellow, during anthesis closely aggregate and sub-
