I.—Introduction. 
mHE observations recorded in the present paper form a con¬ 
tinuation to a study of the early history of the reproductive 
organs of Torreya californica, which was published in The New 
Phytologist in July last. 1 References will be found there to 
previous papers on this plant. A long series of hand sections 
illustrating the development of the ovule was cut by Mrs. Tansley 
from fresh and spirit material collected in 1902, and she obtained 
preparations shewing the archegonia, and embryos, and in at least 
one case the actual entry of the male nucleus into the egg. These 
preparations were handed over to me, and I have found them of the 
greatest possible use. They were especially invaluable in deter¬ 
mining probable dates for the critical stages, and hence in deciding 
when it would be advisable to fix the ovules on the spot. The 
material, as before, was obtained from the beautiful tree in the 
Orton Longueville gardens, and I have to thank Lord Huntly for 
his kindness in not only placing the material at my disposal, but in 
allowing me to collect the ovules myself, and fix them at the tree 
during August and September. I am also indebted to Mr. A. 
Harding, the head gardener, for numerous consignments of material.
