4. N. cnryisiliqua (Hook.), Nutt., var. lyratum, Wats.: N. lyratum, 

 Nutt.; T. & G. Fl. i. 73. Annual or biennial, with several erect or 

 decumbent branching stems seldom 1 ft. long; glabrous, or under a lens 

 sparsely hispidulous: leaves mostly narrowly oblong or oblanceolate 

 and rather regularly pinnatifid into divaricate linear or oblong-lanceolate 

 entire segments: fl. very small, greenish yellow: pods }4 — % in. long, 

 linear, more or less curved, pointed with a prominent style, the valves 

 smooth; pedicels half as long as the pod; seeds m 2 rows. — By streamlets, 

 in the Coast Bange and the Sierra; common in Marin Co. and south- 

 ward. Nothing quite answering to the true N. curvisiliqua is found in 

 middle California; neither indeed is the typical N. lyralum here, and 

 very possibly our plant may prove distinct from both. The northern 

 types of both are of different aspect. 



5. N. occidentale. Annual, erect, I3 — 1 ft. high, sparingly branched 

 a!bove, or rarely from near the base, glabrous (sparsely and retrorsely 

 hispidulous under a lens), leafy at base: leaves rather broadly oblanceo- 

 late, coarsely toothed or somewhat pinnatifid: fl. minute: fruiting raceme 

 elongated and rather dense: pods % — % in. long, linear, straight or 

 slightly curved, abruptly tipped with a short style, obcompressed, % line 

 wide, the thin partition less than 32 line: seeds round-oval, but almost 

 cordate by a deep broad notch at the hilum. — Very common on moist 

 low plains bordering the upper Sacramento, and in the foothills adjacent; 

 a well marked species, most related to the next, though generally labelled 

 "N. curvisiliqua " in the herbaria. The long pods, flattened contrary to 

 the partition, are very characteristic. 



6. N. palustre, DC. Syst. ii. 191 (1821); Moench, Meth. 263 (1794), 

 under Radicula. Rovipa nasturtioides, Spach, Phaner. vi. 506. Stoutish, 

 erect, 2—3 ft. high, branching above, glabrous: leaves oblong-lanceolate 

 in outline, coarsely and irregularly toothed or pinnatifid, 2 — 6 in. long: 

 fl. a line long: pods linear-oblong, 3 — 5 lines long, on slender pedicels; 

 style very short; valves thin, smooth and nerveless: seeds in 2 rows, 

 nearly orbicular, scarcely notched at the hilum. — Either uncommon with 

 us, or very rarely collected. Our only specimen which is clearly of this 

 species comes from Humboldt Co., Cliesnut & Drew. The allied N. his- 

 pidurn, which is hispid-hairy and has globular pods, is in Nevada, near us. 



7. N. dictyotum. Habit and foliage of the last, 2 — 4 ft. high, 

 sparingly hirsute: racemes elongated, rather dense: fl. unknown; pods 

 3 lines long, of ovate-lanceolate outline; valves of very firm texture, 

 usually with a strong rather tortuous midvein and some anastomosing 

 veinlets; partition rather thick, somewhat favose-reticulate by the 

 impressions of the angular seeds. — On Grand Island, of the lower Sacra-
