Christopher Tolkien has said: “My father used to refer to all the big white umbellifers as ‘hemlocks’, although he was well aware that a lot of them were really cow parsley or chervil”引自 Contents
作者给出结论:Tolkien often used hemlocks in a wider sense。所以,hemlock是种泛指,可以是欧芹,也可以是细叶芹,甚至未必是指它们的花朵,因为《魔戒》中弗罗多一行走进老林子的时候也看到了hemlock,但此时已是9月26日,早已过了野芹、欧芹、细叶芹任何一种的花期。
