Scarlet was tabled under red, the few terra-cottas and salmon-pink under red- 
pink, and intermediate colours by intermediate values (e.g. j) or pw). If the 
petal pairs were of different colours, they were recorded as p x w, say, and tabled 
under intermediate values. Veined-white was used for white faintly pink or for 
white with distinct pink veins. 
(iv) Breadth of mai-gin. The classes used were : 
Broad {h). Slight (s). None («)• 
Broad to slight (i.s). Slight to none {sn). 
"None" signifies that the border of the petal was of the same colour as its 
body or middle-third. 
(v) Colour of the margin, if it existed. This was only completely noted in 
the Parkstone crop, and it enabled us to form a classification of the flowers by 
colour at the border of the petal ; this was the same as in the middle-third, if 
there were no separate margin. Colour scale used as in (iii). 
(vi) Intensity of the wrinkling of the petal. This was observed some time, 
12 to 24 hours, after the opening of the flower. But while frilling is a marked 
feature of the Shirley, this character was not a satisfactory one to observe, and but 
little weight can be given to the results. The following classes were adopted : 
Very much wrinkled or frilled (/). Slightly wrinkled (sio). 
Wrinkled (w). Not wrinkled (nw). 
(vii) Base of petal. 
(a) If the petal base differ in colour from the middle-third it may be said to 
have a basal patch, and the following classification of basal patches was adopted : 
None (n). Well defined (d). 
None to slight (ns). Well defined to large (dl). 
Slight (s). Large (I). 
Slight to well defined (sd). 
(^) If there were a basal patch its colour was noted ; Avhite, black and lilac 
basal patches were recorded. 
(viii) The shape of the capsule cover, whether flat or conical, the colour of the 
pollen, and all abnormalities were further noted in a separate column. Actual 
shape of capsules was only fully noted in the Crewe crop.
