and simple few-flowered umbels of white flowers on axil- 

 lary peduncles. Calyx-teeth rather prominent. Fruit 

 broadly ovate with narrow commissure and stellate 

 pubescence. Carpels turgid, becoming depressed on the 

 back, with neither ribs nor oil-tubes ; the whole dorsal 

 region inflated, the seed-cavity being on the commissural 

 side of the carpel. Seed flattened dorsally, the face and 

 back plane or convex. 



1. B. septentrionalis C. & R. Stems weak, 0.5-6 dm. long, 

 dichotomously branching; leaves thin, cordate to reniform, 1.5-3 

 cm. broad, 3-5-lobed, the lobes entire or toothed, on long slender 

 petioles; umbels 1-4-flowered, on short peduncles; fruit about 2 

 mm. long, sessile or nearly so. (B. lobata of recent authors, not

 without ribs. Stylopodium wanting. Oil-tubes mostly 

 large, 5 (3 dorsal and 2 commissural) or in ours 3-many
