Hebetatum (Fig. 290). — Fronds end almost squarely, but with 

 rounded angles, the spore heaps behind radiating like the spokes of 

 a wheel. 



Hendersonii (Fig. 291). — Found near Whitly by J. Henderson ; 

 a dwarf form, but peculiarly pretty, the frond stalk dividing and 

 re-dividing, all the divisions ultimately bearing definitely stalked 

 and similarly fan-crested fronds ; a robuster form on similar lines 

 was found by the writer at Penrhyn, Cornwall, in 1906.
