\ 42 Hermann Wolff. — Umbelliferae-Apioideae-Ammineae heteroclitae. 



Nota. Stirps Franchetiana, cujus specimina mihi non visa, sec. cl. autorem maxime affinis 

 B. odoradiato Bge., a quo recedit foliis breviter sed manifeste petiolatis nee sessilibus, minus 

 nervosis, papyraeeis nee firmis. Cl. Freyn B. pekinense proximum esse B. ranuneuloidi exi- 

 stimavit, a quo differre scripsit caule elatiore, foliis acuminatis, umbellis minoribus, involucri 

 phyllis parvis, acutioribus; mihi e descriptione proximum esse videtur B. falcato var. scor- 

 xonerifolio.
