Native, Brit., 1-7. xMay, II. 



Exceedingly common in every meadow of Holderness, and 

 also in the other divisions. The second week in May merits 

 the distinction of being " Cowslip week," great quantities for 

 the making of the " wine " of this sort being brought to the 

 markets. The hybrid, acaulis X veris, above mentioned is 

 not at all uncommon. A remarkable form, in which all the 

 floral whorls are polyphyllous and the ovules naked ! was 

 gathered near Holmpton, Holderness, by Mr. J. W. Mackay 

 of Hull, May, 1901, and 1902. Sp. /;; Herb., J.F.R.
