nominatorum statu haud culto occurrat, auctor eam Interim pro specie propria habet, dum 

 experimentis institutis de illius plantae positione accuratius judicari possit. Investigationibus 

 macroscopicis et microscopicis auctori persuasum est, N. Hookerianam esse hybrid am inter 

 N. Rafflesianam et ampullariam.
