Figs 22-29. Fig. 22. Polar view of subunit axis showing the initiation of the Y-phyll (c) and a meristeni 
enlarging in the axil of the a-phyll. Fig. 23. Polar view of subunit axis showing initiation of y-phyll 
on leaf side of axis and the enlarging meristem in the axil of the a-phyll. Fig. 24. Axillary subunit 
whowing the flat meristeni enlarging in the axil of the a-phyll. Fig. 25. Polar view of developing 
axillary subunit showing the .sec]uential initiation of bracts (a-0 and the 2/5 spiral after the third (c) 
bract or y-phyll. Fig. 26. Enlargement of meristems in bract axUs. Tlie secondary meristem/subunit 
axis in the [J-phyll has initiated an a- and |J-phyll(a, b): (the a-phyll of the principal subunit axis 
is not visible). Fig. 27. Polar view of enlarging floral meristem. Fig. 28. Oblique view of enlarging 
floral meristem. Fig. 29. Polar view of transversely oblate enlarging floral meristem near top of 
subunit axis. Scale bars: 22-23, 27-29 = 25 pm; 24-26 = 50 pm.
