Nasturtium obtusum, Nutt, in Torr. & Gray, FI. 1, p. 74. River banks, Middle Yuba, May 
2. The North American species of this genus need a careful revision. Thei are probably too 
many of them described in our books. 
Nasturtium curvisiliqua, Nutt. 1. c. Gravelly hills near the Colorado ; Feb uary. Without 
full-grown fruit. 
Barbarea vulgaris, R. Br. ; var. pedicellis angulo recto patulis, etc. Benth. FI. Hartio., p. 
297. Near San Francisco and Punta de los Reyes, April. 
Streptanthus flavescens, Hook. Ic. 1, t. 34; Torr. & Gray, FI. 1, p. 77. River banks, 
Benicia, April 24. Sepals hairy. Pods about an inch and a half long, nearly terete, sparsely 
hirsute, with a long tapering point, strictly erect. Pedicles almost hispid, with spreading or 
reflexed hairs. 
Strepanthus ltnearifolius, Gray, PI. Fendl., p. 7. Gravelly and rocky places, on Hurrah 
creek ; September. The radical and some of the lower cauline leaves are spatulate or obovate, 
and short. 
Strepanthus cordatus, Nutt, in Torr. &Gray, FI. 1 ,"p. 77. River banks, Middle Yuba, May 
21. Stem 2-3 feet high, paniculately branched above ; whole plant very smooth and somewhat 
glaucous. Lower leaves and sometimes the cauline ones reparully or sharply denticulate ; the 
latter about an inch long, mostly obtuse, strongly clasping. Pedicles usually almost as long as 
the flower, spreading and curved upward. Flower buds acute. Calyx very obtuse at the base. 
Sepals with a long narrow acuminate point, the exterior ones carinate, petals spatulate, 
shorter than the calyx. Torus or receptacle dilated. Pods not seen. We have specimens of 
the plant collected in California by Colonel Fremont and Mr. Gibbes. 
Strepanthuslongifolius, Benth. PI. Hartio., p. 10, No. 52. Gray, PL Fendl., p. 6, var. glaber . 
pedicellis brevioribus. Sandy hills near the Colorado of the West. New Mexico, February 22. 
Root annual. Stem about a foot high, slender. Lower leaves acutely repand-dentate ; upper 
ones linear-oblong, entire. Pedicles shorter than the closed calyx, recurved after flowering. 
Petals linear-spatulate, pale purple, a little exserted. Pods (immature) an inch long, with a 
tapering summit. 
Turritis glabra, Linn.; Torr. & Gray, FI. 1 , p. 78. T. macrocarpa, Nutt, in Torr. & Gray, 
FI. 1. c. Near San Francisco, April 3. A dvFarf state of this species was found on Cajon 
creek, March 17. We reduce Nuttall’s T. macrocarpa to T. glabra, as there are often inter¬ 
mediate forms between the two. 
Turritis patula, Graham, in Edinb. Phil. Jour., (1829,) p. 7; Torr. & Gray, FI. 1, p. 79 
Gray, PI. Wright. 2, p. 10. Yuba river, May 22. In all Dr. Bigelow’s specimens of this plant 
the stem-leaves are nearly as hairy as the radical leaves. 
Turritis patula, Graham; Hook. FI. Bor.,-Am. 1 , p. 40 : var. magis hispidula. Hill sides, 
Downieville ; May 22. 
Arabis hirsuta, Scop.; Torr. & Gray, FI. 1 , p. 80. /9. glabrata, Torr. & Gray, l. c. Wet 
ravines, Dufiield’s ranch, Sierra Nevada, May 11, (in flower.) 
Cardamine angulata, Hook. Bot. Misc. 1, p. 343, t. 69 ; Torr. & Gray, FI. 1 , p. 84. C. 
paucisecta, Benth. FI. Hartio., p. 297. Hill-sides, Duffield’s ranch, Sierra Nevada, May 10 ; 
mountains near Oakland, April 4 ; and plains near San Gabriel, March 23. Radical leaves 
sometimes entire ; but more commonly 3-parted, with the segments petiolulate, roundish, entire, 
or obscurely repand-toothed; stem-leaves 3-5-parted; the segments varying in form from broadly 
ovate and cordate to lanceolate, and narrowed at the base, entire, toothed. Flowers as large as 
in Cardamine rhomboidea. Pods erect, an inch and a half long, on a stalk of about the same 
length, 1^ line wide, tapering to a long point. Seeds narrowly margined, distant. Root 
tuberiferous. 
Cardamine oligosperma, Nutt, in Torr. & Gray, PI. 1, p. 85 ; Benth. FI. Hartio. Near San 
Francisco; April 3. Very near C. hirsuta, but differs in the broader pods and less numerous seeds.
