264 CRUCIFER^, 



the region east of the Livermore Valley, thence to the original station, 

 i. e., Monterey. Although this and n. 5 have been placed in different 

 genera, they are with difficulty held distinct as species. The only 

 difference is in the petals; and by these the present plant would stand 

 well in Slreptanihus if its habit and narrow terete pods were not those of 

 the annual Thelypods precisely. 



7. T. rig'idniii, Greene, Pittonia, i. 62 (1887). Stoutish and very rigid, 

 1 — 3 ft. high, with few wide-spread branches : hispidulous below, glabrous 

 above, deep green, not glaucous: lower leaves somewhat lyrately pinna- 

 tifid; upper oblong-lanceolate and laciniate-toothed : fl. yellowish, small, 

 rather crowded and subsessile, the fruiting raceme long and loose : pods 

 1}^ in. long, nearly sessile, ascending or somewhat spreading or curved, 

 rigid, sharply tipped with a short style. — Eastern base of the Mt. Diablo 

 Range, from near Antioch southward, chiefly on clayey hillsides. 



8. T. lasiophylluiii, Greene, Bull. Torr. Club, xiii. 143 (1886); H. & A. 

 Bot. Beech. 321 (184:01, under Turritis. Sisymbrium rejiexum, Nutt. PI. 

 Gamb. 183. Thelypudium neglectiun, M. E. Jones, ? Am. Nat. xvii. 875. 

 Glabrous or more or less hirsiite below, }4 — 6 ft. high, usually stoutish, 

 rather rigidly erect, simple, or sparingly branching above the middle: 

 leaves 2 — 4 in. long, pinnatifid with divaricate toothed segments, or the 

 upper only sinuate-toothed: petals white or yellowish, 11^ — 2}4 lines 

 long: pod slender, nearly terete, 1 — 2 in. long, short-pedicellate, straight 

 or somewhat curved, ascending or strongly deflexed. — Common, and, as 

 to size and pubescence, and the attitude of the pods, very variable. The 

 common form at San Francisco is small, early flowering, and has suberect 

 pods. In the Coast Range the plant is often a yard high or more, late 

 flowering, with pods straight and strongly deflexed. On the plains east of 

 the Mt. Diablo Range grows in great abundance a plant here referred 

 which differs in being glabrous, with pods more or less curved, often 

 spreading only, sometimes deflexed. All these need further examination; 

 and T. negleclum may prove to be one of them. 



13. STANLEYA, NuUall. Stout perennials, with coarse and rather 

 thick glaucous foliage. Flowers yellow, large, in long racemes. Sepals 

 equal at base, spreading. Petals narrow, unguiculate. Stamens elon- 

 gated; anthers linear, at length closely coiled. Pistil stipitate; becoming 

 a long linear pod, with 1 -nerved valves. Seeds in 1 row, oblong, not 

 winged; cotyledons linear, incumbent. — A remarkable genus, chiefly 

 belonging to the Great Basin, with the aspect of Chuine in the preceding 

 family, but genuinely cruciferous in technical character. 



1. S. pinuata, Britt. Trans. N. Y. Acad. viii. 62 (1889); Pursh, Fl. ii. 

 739 (1814), under Cleome: S. pinualifida, Nutt. Gen. ii. 71 (1818); Gray, 

 Gen. 111. i. 154. t. 65. Stems several from a somewhat woody base, 2 — 8
