APPENDIX. 



While this paper was being printed, Chamberlain's paper on " Prothallia 

 and Sporelings of Three New Zealand Species of Lycopodium " (Bot. Gaz., 

 vol. 63, No. 1, 1917, pp. 51-65) came to hand. In it he gives a short 

 account of preserved specimens of the prothalli of L. laterale, L. scariosum, 

 and L. volubile, and also describes the stele of the sporeling of the two last- 

 named species. In Part III of these studies I hope to give an account of 

 the internal structure of the prothalli of seven New Zealand species which 

 were described in Part I, and will compare my results with Chamberlain's 

 observations. In the course of his paper Chamberlain draws attention to 

 the fact that those who have hitherto been at work upon the Lycopodiums 

 have devoted the greater part of their attention to the prothallus and to 

 the adult plant, and that the vascular structure of the sporeling has received 

 little notice. There is no doubt that this has been largely true, although 

 the understanding of the various types of the Lycopodium stele can only 

 come, as Chamberlain remarks, through the comparative study of their 

 ontogenetic development in complexity. I hope to supplement my obser- 

 vations on the vascular structure of the sporelings of eight New Zealand 

 species given in Part I of these studies by a more detailed account in 

 a further contribution, now partially completed. This will include also an 

 account of the vascular structure of the adventitious plantlets described 

 in the present paper, and will deal as well with the young plants of one 

 or two other New Zealand species found by me.
