Flowers of St achy s sy /vatic a , Linn . 41 1 
The next series (see Table II) was collected on the chalk near High 
Wycombe, late in September and early in October, 1917. There is only 
one record of an abnormal side flower. Its formula gives an idea of its 
nature: K4, C 1+4, A 2, G (2). A similar flower has this formula in my 
notes — K3, C 2 + 3, A 2, G (2), but it is not recorded whether it is a side or 
a middle flower. All the others were middle flowers. Of these, two showed 
five stamens, in one case with a forked upper lip (Fig. 2, c), and in the 
other with an upper lip resembling a side lobe of the lower lip ; another 
two showed upper lips similar to the corolla ; in one of these there were 
four sepals and in the other six.

x = opposite half- verticillasters. N.S.F. = normal side flower, i s.p. = upper lip like a side 
petal. S.E. = side flower. 
The other variants recorded were fusions occurring in opposite half- 
verticillasters between a middle flower and a side flower ; one of these free 
side flowers was normal, the other was unopened but possibly normal, with 
five sepals. On the side with the opened flower, only ten sepals were shown, 
the rest of the flower having fallen off. On the other side the following 
formula expresses the state of affairs : 
i + 3 ? 
K 10, C 1 + 3, A 7 or 8 G (2) + (3) 
Under C the first series of figures expresses the condition of the upper 
lip and the second series (after the + ) that of the lower lip ; e. g. here there 
are two lower lips with three lobes to each. There was another fusion in 
which there seemed to be three upper lips (not adjoining) with three groups 
of stamens ; this was slightly injured, however, and will not be further 
considered. The interesting forms in this series were those in which the 
upper lip resembled the side lobe of the lower lip (Fig. 2, b and d), for 
these must be regarded as transitional to the peloric and semi-peloric forms 
which have been found on chalk in July and two of which have been 
noticed, in September, 1919, on plants growing on a loam. These will be 
described below. There was a tendency to reduction in the forms
