male cone by Thibout, a short reference to the plant by Spiess 1 , 
and an account of the wood by Beust, referred to by Gothan 2 , 
appear to complete the literature relating directly to the genus 3 . 
For the material on which the following account is based, 1 
have to thank Mr. H. M. Imbert-Terry, of Strete Ralegh, Exeter, 
who possesses two of the few trees of any considerable size in 
Great Britain. 
The Stem. 
The stem has a central pith consisting of rather thick-walled 
loosely-packed cells, and xylem and phloem arranged as in all 
Conifers. In the cortex just outside the phloem is a ring of resin- 
canals of the usual type, each canal corresponding apparently to 
one of the primary vascular bundles. In older stems, certain cells, 
occurring singly or in groups in the cortex and pith, have their 
walls considerably thickened. 
The tracheids of the secondary xylem, at any rate in plants grown 
in England, are small, with uniseriate pitting on the radial walls. 
Beust 4 found that the pits are somewhat Araucarian in character, 
inasmuch as they are flattened horizontally. Gothan 3 finds this is

suspicion of the Araucarian type of pitting, x 300. 
also the case in several species of Dacrydium, where the pits are 
two-ranked and alternate, being therefore still more Araucarian 
than those of Saxegothsea. I have found in Saxegothaea an

3 Since this paper was written my attention has been called to a 
recent contribution by M. Tison on “ Le nucelle stigmatif&re 
et la pollinisation chez le Saxe-Gothaea conspicua,” Comptes 
Rendus CXLVII., p. 137, July 1908.
