' It may perhaps be desirable that the Society should have a de- 
tailed account of my experiments on effecting unions between the 
P. vulgaris, var. rubra, and the others, viz. P. vulgaris, and var. alba. 
As in that above given, the remarkable results are alone stated— 
the absolute zero of fertility, apparently, attained between un- 
doubted varieties of a species!* By way of a preliminary to the 
* The pure descent of the red and white Primrose from the common yellow 
has been questioned, and a hybrid origin from the Cowslip and Primrose (E. 
veris and P. vulgaris) ascribed to them. To my mind, the latter view is nega- 
tived by the results given in the above table. It is there shown that both (red 
and white) forms are, relatively to the results of similar unions with the common
