 S. (?) teres, Torr. & Gray, Fl. i. 93. Cardamine teres, Michx. Fl. ii. 29. —South Carolina to 

 Florida and west to Texas and Mexico. What is recognized as N. MexicAnum, DC, of 

 Mexico, is a very similar species with somewhat stouter and obtuser pods, often deflexed, 

 and larger minutely tuberculate paler seeds. The West Indian N. brevipes, Griseb., how- 

 ever, may rather be regarded as a variety (insularum) of N. tanacetifolium. Its seeds are 

 similar in color and marking, but the pods are shorter and the style very short or stigma 

 nearly sessile. 

 N. sessiliflorum, Nutt. Glabrous, erect, branching, 2 feet high or less : leaves oblanceo- 

 late, usually obtuse, coarsely toothed or lyrately pinnatifid with few short segments : pedi- 

 cels very short (the lowest rarely 1 to 1^ lines long) : pods spreading, thick and cylindrical, 

 3 or 4 lines long, obtuse ; style very short ; seeds minutely pitted. — Nutt. in Torr. & Gray, 

 Fl. i. 73; Gray, Gen. 111. i. 132, t. 53, excl. f. 1-5. N. limosum, Nutt. 1. c — From Illinois 

 and Missouri to Georgia and Texas. ^ 



Kecently published species not seen by the editor. 

 N.* dictyotum, Greene. "Stout, erect, 2 to 4 feet high, hirsute-pubescent: racemes 

 rather dense : pods ovate-lanceolate ; valves firm in texture, with strong tortuous midvein 

 and anastomosing veinlets ; partition thick, favose-reticulate." — Fl. Francis. 268. Roripa 

 dictyota, Greene, Man. Bay-Reg. 20 (whence the foregoing descr.). — " Marshes of the Lower 

 Sacramento." 



RoRfPA TENERRiMA, Grccue. " Anuual, weak and decumbent, very sparingly branching, 

 6 to 10 inches high, of delicate texture and glabrous : leaves few, lyrate-pinnatifid, the terminal 

 lobe acutish : rhachis of the few racemes almost capillary : pods rather distant, subconical, 

 slightly curved, the tapering apex surmounted by a considerable beak-like style ; valves and 

 septum both very thin: seeds many, in 2 rows under each valve." — Erythea, iii. 46 (whence 

 descr.). — " Modoc Co., Calif., ISfrs. Austin." 



35. BARBAREA, R. Br. Winter Cress. (Name from Erysimum Bar- 

 barea, L., the most common species, and sometimes called Herb of St. Barbara.) 

 — Chiefly biennials, somewhat succulent, sharing most of the characters of 

 Nasturtium, but with somewhat stouter habit, more elongated rigid capsules and 

 uniseriate seeds. — R. Br. in Ait. f. Kew. ed. 2, iv. 109; DC. Syst. ii. 205, & 

 Prodr. i. 140 ; Gray, Gen. 111. i. 147, t. 62 ; Reichenb. Ic. Fl. Germ. ii. t. 47-49 ; 

 Benth. & Hook, Gen. i. 68. — Spec, of difficult limitation. [By B. L. Robinson.] 



B. vulgaris, R. Br. 1. c. (Common Winter Cress, Yellow Rocket.) Stems erect, 

 furrowed-augulate, simple or corymbosely branched, leafy, 1 to 3 feet high : radical leaves 

 and lower cauline usually pinnately parted ; the terminal segment ovate or orbicular, 

 rounded at the apex and varying from cnneate to cordate at the base, entire or with a few 

 rounded teeth or lobes ; lateral segments very variable, usually about 3 (0 to 5) pairs, oblong, 

 entire or toothed ; petioles auriculate-appendaged at the base ; upper leaves simplified, 

 oblanceolate, cut-toothed, sessile, clasping at base : flowers in a short dense oblong raceme, 

 bright yellow : petals nearly or quite twice as long as the sepals : pods from the first ascend- 

 ing or suberect upon more or less spreading pedicels. — DC. Syst. ii. 206, in part. Barbarea 

 Barbarea, MacMillan, Metasp. Minn. Val. 259. Erysimum Barbarea, L. Spec. ii. 660; Fl. 

 Dan. t. 985; Eng. Bot. t. 443. — Moist meadows, brooksides, &c. ; in America chiefly the 

 formal variety arcuAta, Fries (Consp. fasc. vi. no. 17), with inflorescence somewhat lax 

 and elongated even in anthesis and young pods rather widely spreailing and more or less 

 curved ; a form common in the Northern and Middle States across the continent and north- 

 ward to Labrador and Alaska, and on the Pacific Slope southward to Lower Calif., Orcutt.
