that time as if they had no close relations to each other, 

 as the seed in question was thought to have had a much 

 fleshy outer layer of the integument, just as we see in Cycads 

 among living Gymnosperms. But when we carefully examine 

 the distinguishing characters of Araucarineae and the generic 

 diagnoses of this group, and note the fact of the freedom of 

 nucellus in the Araucarian group (afte Richard's and Eich- 

 ler's figures), we can hardly fail to associate Yezostrohus 

 with Araucaria. In both the seed is adherent to the scale, 

 a condition which may impart an appearance to this seed, 

 as if it had a fleshy pulp somewhat resembling that of a 

 Cycadian seed, especially when we judge from the sections 

 which passed through the tip of the ovule and simultaneously 

 the base of the scale, as it will likely happen with inverted 

 ovules. I think this led us to the mistake. If we compare 

 Eichler's original figures of seeds of Araucaria hrasiliana, 

 one of which is reproduced with certain modifications and in 

 a smaller scale in Engler-Prantl's Die Naturl. Pflanzen 

 familien, with the diagram 13 of Yezostrohus given in our text 

 (Stopes and Fujii, I.e. p. 34.), the resemblance between the two 

 is striking. 



A single seed on the seminiferous scale, the inverted ovule 

 the adherency or fusion of the ovule with the scale, the forma 

 tion of a definite cone, and the freedom of nucellus down to the 

 base are the chief characters which associate this seed with 

 plants of the genus Araucaria, although it is probably to be 

 put under a subfamily specially established to include this seed. 



The state of occurrence of the seminiferous scales, which are 

 hitherto never found in connection with the cone axis, shows 

 that the cone broke down when ripe as the scales detach from 

 the cone axis, a habit which likewise indicates an Araucarian 

 affinity. 



Now when we turn to Yezonia, provisionally the vegetative 

 axis of Yezostrohus, we remember of peculiar zones of the thin 

 walled and the thick walled wood elements as clearly shown in 

 the text figs. 9. 10. (Stopes and Fujn, 1910. I.e. pp. 24 and 25).
