Nota. Inter tres species gerontogaeas huius subgeneris G. chinensis unica sine dubio in 

 China crescit. Specimina omnia in China collecta mihi visa huic speciei atlribuenda erant; 

 quarc mihi valde dubium videtur, num G mas recte in monte Altai et in China inveniri dicatur; 

 verosimiliter quod qui referunt autores G. mas cum altera specie orientali-asiatica conf'undcbant. 

 Neque vero, quoad ego ex speciminibus mihi visis concludere possum, G officinalis in China 

 sponte crescit, sed in Japonia sola invenitur.
