Note 6 — (Plates I.–VIII.)
Reading edition
In his paper on the “Distribution of Arctic Plants,” Trans. Linn. Soc. xxiii. p. 310, Dr. Hooker says:—
“The most able and experienced descriptive botanists vary in their estimate of the value of the ‘specific term’ to a much greater extent than is generally supposed.”
“I think I may safely affirm that the ‘specific term’ has three different standard values, all current in descriptive botany, but each more or less confined to one class of observers.”
“This is no question of what is right or wrong as to the real value of the specific term; I believe each is right according to the standard he assumes as the specific.”
