a paper by Miss M. G. Sykes was read entitled “ The Anatomy of 
Welwitschia mirabilis, in the Seedling and J Adult Stages,” of which

bearing inflorescences has been studied. The outer ridges 
originate as two small projections between the margins o he

ring of bundles is differentiated ; ponte: and the bundles supplying 
the inflorescences are composed entirely of secondary elements, 
and are later prolonged aacaies to join the four concentric
