a quo diversa caule elatiore, foliis aculis, cuspidatis, umbellis multo angustioribus, involucri

Nota 2. Suspicor specimina in Alaska collecta et ab autoribus ad B. awcrfea?iMW« relata 
ad B. ranunculoides var. triradiatum Reg. pertinere; forsan species sub titulo subspeciei vel 
varietatis cum B. ranuncidoidi conjungenda est. 
»This species is so variable in foliage that varieties would seem admissible. Resemblancc 
to the European B. ranunculoides is well shown by low forins witb rather small oblong thin 
leaves and quite prominent bractlets; wbile more abundant in collections are the larger forms 
with elongated linear-lanceolate rather rigid stem-leaves and smaller bractels. In the European 
species referred to, and to which our species bas been heretofore referred, the oil-tubes are large 
and solitary, wbile in our species they are so numerous (about 23) as to be continuous about 
the seed-cavity. In habit there is a close resemblancc to tbe European species.« (Coult. et Rose).
