Text-fig. 5. Tempskya Rossica, a restoration of the " tree-fern "-like falso 

 stem resulting from the union of numerous small steins in a plexus 

 of their own roots. The individual small stems stand up freely at the 

 apex of the composite growth, and bear compound (?) foliage leaves. 

 (Hitherto unpublished restoration, provided by Dr. Kidston and 

 Prof. Gwynne-Vaughan.)
