1116 Thoday.—The Female Inflorescence and Ovules of 
reminds one of the ‘assise rayonnante’ in Bennettites Morierei as described 
by Lignier. 1 
At the extreme tip of the integument the fibrous layer dies out, 
and only a thin band of parenchymatous tissue remains, tightly clasped 
round the micropylar tube.

Text-fig. ii, A-K. Transverse sections through apex of ovule. A (slightly oblique) level of 
freedom of inner integument and termination of its vascular bundles : outer integument already 
shows some reduction in the number of its bundles. B through nucellar cap; Bj is through extreme 
tip of nucellar cap and base of micropylar tube. C shows star-like arrangement of fibrous layer in 
outer integument; palisade layer and hypodermal strands have died out. D = termination of fibrous 
layer. - i E = parenchymatous tip of outer integument; micropylar opening reduced to a mere 
slit. F = micropylar tube almost solid. G = solid micropylar tube, enclosed by tip of outer 
integument, surrounded by base of down-growing flange. H = solid micropylar tube with wide 
flange, separate on one side, showing tip of outer integument projecting upwards. I = cavity 
beginning to reappear in micropylar tube; radial lines indicate divisions to form flange. K = just 
below withered tip of micropylar tube. 
The innermost covering or inner integument is coalescent with the 
nucellus for about two-thirds of the length of the latter ; its free por¬ 
tion encircles the nucellar cap and projects for some distance beyond 
the nucellus as the micropylar tube. At this stage the tip of the tube
