Yule, G. U. 1902. Variation of the number of sepals in Anemone 
nemorosa. Biometrika I: 307—309. 
EXPLANATION OF PLATES 10-13 
PLATE 10 
Field view of chicory crop of 1916. Field label 49 designates a series of the tall- 
growing race [race 6, series (Ex X А)-10-8-І5-|. Plants of the semi-dwarf 
bushy race (race 5) are де at the right [series (Ев X А)-10-13-5-,І in front 
[series (E2 X A)—10-13-13-], and at left [series (Ez X A)—10—13-12-] of field 
label 49. Field label 53 marks a series (A X Ез)-0-5-6-, of the brittle-stemmed 
race (race 4). 
PLATE II 
w in field of chicory, crop of 1916. To left, field label 53 marks a series of the 
Ша race shown also іп plate 10. Next to the right are plants of the 
w гасе [race 1, series (A X Е»)-4-3-11-І. In front of label 63 are plants 
ч m dwarf race [race 2, series (A X Es:)-4-6-3-]. Field label 63 designates plants 
of series (А X E:)-0-5-6—- and label 57 marks series (A X E»»)-9-4-10-, both of 
which constitute distinct races thus far unnamed. 
PLATE 12 
Branches of chicory from near middle part of plants. A is from the wild white- 
flowered plant A used as а parent of various families; B is from plant Es of the 
variety Barbe de Capucin, and C is from an Fi hybrid of E; X A 
ds that are solitary and on terminal or elongated stems are indicated by r. 
Sessile flower heads lateral to more terminal heads are indicated by 2. Clusters of 
sessile "a are shown at 3 
As shown, especially in Ж. the terminal head blooms before a head that is imme- 
diately m to it. In the flower clusters the first head to bloom is the main 
terminal. 
The three branches illustrate some of the variations that occur in regard to the 
number of solitary and grouped heads 
PLATE I3 
Segments of a single large branch from each of four different plants showing the 
grouping of heads, the relative development of successive laterals on a branch, and 
variation which is seen in different plants (individual variability) in the character 
of the clusters of flower heads 
А is from a plant of the variety red-leaved Treviso. (В. ser. rr, no. 14). At 8 
is a terminal жаланы. with. а „иу head at apex and at first node. Segments 7 
to 4 inclusi nd a single lateral at each node with various stages of 
арм of the pe bearing the terminal. Segments 1, 2, and 3 show further 
development; the succession of bloom indicated by letters.
