Conioselinum Fischeri, Hook. Fl. Bor. Amer. i. 265, et Hook. et Arn. Bot. Beech. 124, non DC., 
species 2 subarcticas Selini includit, inter se involucellis foliisque facile distinctas, et ambse vittis 
sub valleculis solitariis instrüctze, additis hinc inde vittis ut in Lomatocaro intrajugalibus. C. cana- 
dense, Torr. e& Gr. Fl. N. Amer. i. 619; Torr. Fl. N. York, t. 35, etiam ad Selinum (ex fructu adhue 
immaturo) pertinere videtur. €. Fischeri, e vicino maris Ochotek in Coll. Amer. Expl. Exped. e

malia, Europea et Asiatica, nullo puncto a Ligustico distinguere possumus.
