Wigand, 'Flora,' 1856, mentions a similar change in carex glauca.
The natives cultivate, in the lagune of Chalco, a sort of carex called tout, on which the insects readily deposit their eggs.
There are forty-six kinds of sedge (carex), or if the Scirpus tribe be added, sixty-one, found in our islands.
We found there a curious black-headed grass which proved to be of the carex genus.
In the more damp and marshy places the bottom is covered with marsh trefoil, carex, smooth equisetum, and rush.
On carex glauca and other sedges, eating down the stems close to the roots.
It is not a grass but a sedge (carex glauca or C. panicea) with leaves rather like those of a carnation.
Inside the “finsko” we used, at the beginning of our journey, this “sennegraes” (carex æsicaria), of which we had taken a supply.
The land here is more elevated and less marshy, though somewhat impaired by tumps (of carex cspitosa).
The sedges (carex) dry and colour well, as also several of the water-rushes, reeds, and flags.
