In cross-section a staminate cone shows about ten to twelve sporo-

 Just outside of the bundle there usually is found a resin canal (fig. i).

The resin canals contain little material of any sort in the preparations 

 available for study. The distinctly glandular cells lining them 

 (fig. 2) suggest, however, that they are functional. The number 

 varies in different strobili, but in those examined did not fall below 

 six nor exceed eighteen or twenty. 



The sporophylls as seen from the upper surface are somewhat 

 spatulate, with a rather pointed apex. Fig. 4 presents an outline 



1 We have received from Dr. Cockayne two excellent photographs of P. dacry- 

 dioides, which are reproduced on account of their general interest (figs. A and B).
