smaller than in E. cheiranthoides. Petals obovate-cuneate, scarcely 

 longer than the calyx. Pedicels of the fruit 2 to 3 lines long, a little 

 hairy, abruptly bent downward. Pods an inch and a half long, and 

 nearly a line wide, distinctly quadrangular. Stigma minute. Seeds 

 in a single row, oblong. Cotyledons incumbent. [This needs to be 

 compared with Sisymbrium deflexum of Harvey, which is also Turritis? 

 lasiophylla, Hook. & Arm, and which, in a form having less pinnatifid 

 leaves, extends into Oregon.] 



11. THELYPODIUM, Endl (Pachypodium, Nutt.) 



1. Thelypodium laciniatum, Endl. 



Hab. On the Columbia and Kooskooskee Rivers. — The mature pods 

 are three inches or more in length, in an elongated raceme. 



2. Thelypodium brachycarpum, Sp. Nov. (Tab. 1.) 



T.foliis radicalibus lyrato-pimiatiftdis, caidinis lanceolato-oblongis basi 

 sagittatis amplexicaulibus integerrimis ; racemis spicij brmibus, floribus 

 subsessilibus ; petalis calyce 2-3-p?o longioribus anguste linear ibus; 

 siliquis oblongo-linearibus ; stipite brevissimo. 



Hab. On the Klamet River, southern borders of Oregon. — Whole 

 plant smooth. Root biennial. Stem 2 or 3 feet high, fastigiately 

 branched. Radical leaves about 2 inches long; the lobes somewhat 

 toothed : cauline leaves acute or obtuse, an inch long, apparently 

 rather fleshy; the auricles rounded. Pedicels scarcely a line in 

 length. Sepals oblong. Petals white, extremely narrow and of 

 nearly uniform breadth throughout, apparently twisted. Pods in a 

 short close raceme, 6 to 9 lines long, nearly terete, somewhat toru- 

 lose, abruptly pointed with the very short style. Seeds 6 to 9 in each 

 cell, oblong, not margined. Cotyledons obliquely incumbent. A well- 

 marked species, resembling T. laciniatum in its very long narrow 

 petals, and P. sagittatum in its leaves; but differing from both in its 

 short almost sessile pods.
