 Carpinus triflora Moench meth. p. 394. Auctores nonnulli plurimos characteres

 nihil mihi certum nisi nervi laterales pauciores in arbore americana, quod 

 etiam in foliis longe acuminatis (Linden! 26) paulo dubium evenit. Strobili 

 nunquam cernui ex Pursh fl. am. 2, p. 624, quod negat cl. Spach; erecti et 

 demum cernui ex Emerson 1. c. In herbariis erectos plerumque vidi in ame- 

 ricana, cernuos in gerontogea, sed interdum rami flaccidi exsiccantur et inde 

 char. in sicco dubius. Pili fol. et ramorum breviores in americanS, sed in 

 ipso ramo variare semel vidi. Ex Willd. novella pilis apice glandulosis gau- 

 dent, quod variat ex Spach. Bracteae fruct. interne magis pubescentes (an 

 semper?) Limbus perig. ex Spach major in americana, sed ex obs. (non satis 

 numerosis) nihil certum vidi. Tandem aut species vix differunt, aut arbores 

 cultae confusae vel male obs. in errores traxerunt. (v. s.)
