ON SOME POINTS OP RESEMBLANCE BETWEEN 
GNETALEAN AND BENNETT1TEAN SEEDS. 
By Emily M. Berridge, B.Sc. 
[Text-Figs. 1—5], 
X N the spring of the year 1908 some ovules of Gnetuvi gneinon, 
originally obtained from Kew, furnished me with a series of 
sections which showed a curious blocking of the micropyle by 
secondary growth of the tissues of the wall after the time for 
fertilization was past. 
This fact of the closing of the micropyle in the young seed is 
mainly of interest on account of the light it may throw on 
Fig. 1. Longitudinal section through upper half of young seed of Gnetum 
gnemon. p, perianth; o.t., outer integument; i.t., inner integument; p.c., 
pollen-chamber ; emb., embryo; m., micropyle. The levels of the transverse 
sections represented in Figs. 2, 3, 4 and 5 are indicated. x25.
