462 MISS L. S. GIBBS ON THE 
peculiarity of these secondary shoots with their very dissimilar 
leaves which led Mr. Moore, loc. cit., to make his var. repens, 
S. Moore. His second var. elatior, 8. Moore, was based on an 
unusually long primary shoot collected without the radical 
leaves. With incomplete material not showing the actual con- 
nections it would be impossible to make out the sequence of 
events.—L. S. G.]
