176 Benson . — Telangium Scotti , a new Species of 
6. The compartments are comparable in size with the nucellus. 
7 . The compartments vary in number in the same way as the members 
of many Palaeozoic synangia. 
8. The integument of many of the seeds undergoes septicidal dehis- 
cence like a synangium. 
9. The integument is generally as concrescent with the nucellus as the 
members of a synangium are with one another. 
In conclusion, I may add that though I regard the theory as of wide- 
reaching importance, I am only concerned at present to put it forward as 
probably the true interpretation of the canopy of Lagenostoma y and hence 
as adding support to the view that Telangium Scotti is the micro- 
sporangial sorus of Lyginodendron . The full exposition of the seed which 
we await from Prof. Oliver will be based on wider researches into primitive 
types and a more intimate acquaintance with the difficulties of the problem. 
I cannot conclude without expressing my indebtedness to Dr. Scott 
and Prof. F. W. Oliver. The stimulus of their example and criticism 
and their kindness in lending valuable slides have been most helpful.
