Kew is indebted to Berlin for the loan of the type specimens of 

 S. eglandidosumy Ule, from which the accompanying plate was pre- 

 pared, and also for some detached leaves and portions of female spikes 

 past the flowering stage. Dr. Ule gave the specific name under the 

 impression that petiolar glands were always wanting, but they are 

 sometimes evident and often present in a rudimentary condition 

 hardly visible to the naked eye. 



This species differs from all the others that I have examined in the 

 lateral female spikes being seated at the base of the male spikes ; but 

 as only exceedingly young female flowers were present tlieir structure 

 was not quite clear to me. — W. Botting Hemsley.
