CocHLEARIA cyclocarpa, n. sp. a basi ramosa caulibus multis 
adscendentibus 11-24 cm. altis; foliis rosulae deltoideo-ovalibus 
integris vel leviter sinuato-dentatis basi truncatis vel cordatis 1-1.5 
cm. longis latisque, petiolis 5-8 cm. longis; foliis caulinis inferioribus 
ovalibus vel oblongis obtusis sinuate paucidentatis in petiolos mar- 
ginatos angustatis vel subsessilibus 1.5-2.5 cm. longis, superioribus 
sensim minoribus plerumque hastate 3-5-dentatis vel rare ovalibus 
integris leviter amplectentibus; racemis 2-10 cm. longis; pedicellis 
patentibus vel adscendentibus 5-15 (plerumque 7) mm. longis; 
sepalis oblongis 2 mm. longis; petalis albis obovatis 3 mm. longis ad 
medium in unguiculum angustatis; siliculis valde reticulatis vix 
inflatis rotundatis vel depresso-rotundatis 5-7 mm. longis latisque; 
seminibus in quoque loculo 6 longitudine 1.5 mm.; stylo in ovario 
0.5 mm. in fructo 0.8 mm. longo. 
Branching from the base, with many ascending stems 11-24 cm. 
high: leaves of the rosette deltoid-oval, entire or slightly sinuate- 
dentate, truncate or cordate at base, 1-1.5 em. long and wide; petioles 
5-8 cm. long: lower cauline leaves oval or oblong, obtuse, sinuately, few- 
toothed, narrowed into margined petioles or subsessile, 1.5-2.5 cm. 
long; the upper gradually smaller, mostly hastately, 3—5-toothed or 
rarely oval and entire, slightly clasping: racemes 2-10 cm. long: 
pedicels spreading or ascending, 5-15 (commonly 7) mm. long: 
sepals oblong, 2 mm. long: petals white, obovate, 3 mm. long, nar- 
rowed at the middle into a claw: siliques obviously reticulated, 
scarcely inflated, round or depressed-orbicular, 5-7 mm. long and wide: 
seeds 6 in each cell, 1.5 mm. in length: style 0.5 mm. long when young, 
0.8 mm. long in fruit.— NEWFOUNDLAND: wet conglomerate lime-

This species, which is most closely related among described species 
to Cochlearia anglica L., as which it has been passing in American 
literature, differs from that plant in its circular less reticulate pods, 
its smaller frequently cordate basal leaves, much shorter style, and 
smaller flowers. In C. anglica the rosette-leaves are ovate or oval- 
oblong, large, cuneate or often rounded or sometimes truncate into 
the petiole, the pods are ellipsoid and typically much larger (rarely
