 sagittate base : putala 2 to 3 lines long, little exceeding the sepals : pods erect uiid 

 usually ai)pressed, 2 to -i inches long, less than a lino wide, nearly straight, ou ped- 

 icels 3 to 4 lines long; style sliort ; stigma li-lobed : seeds in two rows, narrowly 

 winged or Avingless. - Tarritis ijlairu, i.inn., aiitl T, m(icn>r((r/-a, Is'ul.l. ; Torr. it

In the mountains IVoni Sun Diego to the British Boundary and northward, and east across the 

 continent ; also in Europe and N. Asia. 



A. JiiHSUTA, Scop., has not been certainly found in California, but is frequent in the I'oluuibia 

 Valley and northward, and also east to Colorado and the Atlantic. Jt is usually more skndi r 

 and hii-sute than the last, 1 to 2 feet hij,di, the stems often clustered and with sIliuUt .strict 

 branches iibove ; leaves often rosulate at the bu.sc, 1 Ui 2 inches long, tho cauline ovale to olilong 

 or lanceolate ; pod shorter, 1 to 2 inches long, narrower, the wingless seeds strii:lly in one row. 



A. sPAinuLAiA, Nutt., is another nearly allied species, but little known, which may occur 

 in the State, having been found in Oregon and W. Kcvada (if No. G7 Jrutsoii be correctly 

 referred to it). It a[ipears to be a low .slender plant, much like snudl forms of yt. liimalu, but 

 with fewer leaves, those ujion the stem scattered and entire ; peilicels s)>reading ; jiods still 

 narrower, less than an inch long, beaked with a nariow style. 



* * * Mostly pei-ennials : pods erect or asceuding : flowers viostly larger, deeper 



colored. 



3. A. Lyallii, Watson. Bright green or glaucous and glabi'ous, or usually 

 Komewlnit ^Mllons below with spreading hairs, especially on the nnirgin of tbo peti- 

 oles, rarely more or less canescent with stellate pubescenco : stems slender I'rom a 

 branching perennial base, 2 to 15 inches high : radical leaves oblanceolate, on slender 

 petioles, acute, entire ; cauline oblong-lanceolate, clasping and sagittate at base : 

 petals liglit pink, about 3 lines long, twice long*!r than the sepals : style none : ])ods 

 straight, narrowly linear, 1 to 3 inches long : seeds in 2 rows, narrowly winged. —

In the high Sierra Nevada from Mono Pass to Washington Terntory, and also eastward to 

 Utah and W. "Wyoming ; often aljiine and dwarf. A somewhat variable subal])ine and alpine 

 si)ecies, distinguished by its perennial root from ^/. iJrinirinondii, which seems not to occur west 

 of the Eocky Mountains. 



A. canilSckns, Nutt., of the mountains in K. Nevada and Wyoming, is like smaller forms of 

 A. Lyallii, but is densely stellatc-tomento.se, the somewhat broader pods refle.xed and* often 

 secund, and the seeds in one row and more broadly winged. 



4. A. platysperma, CJray. Canescent with a sliort stellate pubescence : stems 

 several from a perennial base, slender, 4 to 1 2 inclie.s high : leaves entire, the lower 

 oblanceolate or spatuiate, an inch long ; the cauline oblong-lanceolate, sessile but 

 not auricled at base, 4 to 10 lines long : i)etals rose-eolore«l, 2 to 3 lines long : pods 

 straight, erect, 1 to 2 inches long and 2 lines wide, acuminate, without style, 

 loosely reticulated : seeds in one row, with a broad tliiu wing. — Proc Am. Acad. 

 vi. 519 ; Watson, Bot. King Exp. IG. 



Alpine or subalpine in the Sierra Nevada from tlie Yosemite to Mt. Shasta ; in the East Hum- 

 boldt Mountains, Nevada, IVatson. 



5. A. blepbarophylla, Hook. & Arn. Smooth or slightly villous, tlu) stems 

 often tuft(;d, 4 to 1 2 inches higli : leaves strongly ciliate, entire or sparingly sinuate- 

 toothed, the lower obovate or broadly spatuiate, 1 to 2 inclu's long, the cauline 

 oblong, sessile, obtuse* or acutish : llowers large ; sepals generally colored ; petals 

 bright purple, G to 9 lines long: ]»ods 1 to 1| inches long and as many lines broad, 

 beaked with the short stout style, loosely spreading : seeds in one row, a line in 

 diameter, wingless or narrowly margined. — Bot. Beechey, 321 ; Bot. Mag. t. 6087. 



On low hills near the coast, from San Francisco to Monterey. Blooming in early spring and 

 " superb in cultivation." 



6. A. repanda, W^atson. liiennial, pubescent especially below with loose 

 branched hairs : stem rather stout and coarse, 2 feet high, and with the apreading
