in that species, with the other characters exactly intermediate, as 
described above. The apparent absence of S. lacustris from the 
area covered by carinatus may be considered by some as a point 
against its hybrid origin, but it will be well to point out that S, 
lacustris has been recorded from Strawberry Hill, which is some 
miles west of the above-mentioned locality. Having regard to the 
fact that both the assumed parents do not grow in close proximit}% 
it is, of course, possible to regard S. carinatus as a secondary 
hybrid. These secondary hybrids in the course of generations 
often simulate good species and may even become so, as for 
instance, Potaitilla aurulenta, which has arisen from the primary 
hybrid combination P. verna X opaca. Scirpus carmatus has not 
advanced so far, but its great variation is a sufficiently clear 
indication of its hybrid origin. It is interesting to note that 
S. carinatus and 6". triquetcr are associated on tlie banks of the 
Arun, near Amberley, Sussex, and by the Tamar, near Calstock, 
Cornwall. I am unable to ascertain whether .S. lacustris grows 
near Amberley, but it is not recorded from the banks of the Tamar 
in Davey’s list of Cornwall plants. — A. B. Jackson and K. 
Domin. S. carinatus is widely spread on the Continent, where 
it is apparently often associated with S. triquetcr. — A. B. Jackson.
