S topes. — An Early Type of the 
it comes from Australasia, where no Abietineae or Juniperineae or other 
forms with ‘ Abietinean ’ ray structure are endemic at present. 
8. The well-marked growth rings, with their large proportion of greatly 
thickened elements, confirm the conclusions regarding the climatic con- 
ditions of this region at the time the plant was alive, which were drawn from 
the first specimen ( Araucarioxylon Novae Z eelandii) described from Amuri 
Bluff, and held to indicate the contemporary existence of well-marked 
seasons. 
The expenses incurred in photographing the specimens were defrayed 
out of a Royal Society Grant. 
DESCRIPTION OF PLATE IV. 
Illustrating Dr. Stopes’s paper on An Early Type of the Abietineae {?). 
Fig. i. Transverse section of wood, showing the well-marked growth rings and large square 
spring tracheides. 
Fig. 2. Radial longitudinal section of the spring tracheides, showing the typical Araucarian type 
of pitting. In the rays indications of the rows of three pits per tracheide-field can be seen. 
Fig. 3. Radial longitudinal section of a ray, showing the vertical pairs of pits per tracheide- 
field, /., and the ‘ Abietinean pitting’ in the end wall, ep. (cf. Text-fig. 3). 
Fig. 4. Tangential longitudinal section of rays, showing the ‘Abietinean pitting’ of the end 
wall, ep. 
Fig. 5. Lower power view of radial longitudinal section, showing at a the ‘Abietinean’ 
thickening and pitting of the ray cells.
