Nota, Slirps Franchetiana, cujus specimina mihi non visa, sec. cl. autorem maxime affinis 
B. octoradiato Bge., a quo recedit foliis hreviler sed manifeste petiolatis nec sessilibus, minus 
nervosis, papyraceis nec firmis. Cl. Freyn B. pekinensc proximum esse B. ranunculoidi exi- 
stimavit, a quo ditferre scripsit caule elatiore, foliis acuminatis, umbellis minoribus, involucri 
phyllis parvis, acutioribus; mihi e descriptione proximum esse videtur B. falcato var. scar- 
■xonerifolio.
