sorted to measurements in my descriptions« as affording something like precision in character, and I have taken
the scale of Vahl in his paper in Act. Holm, as my standard. This has given me trouble, but labor ipsa
voluptas. I shall go on and prepare a monograph of the genus, describing a few new species in a paper for
the Linneean Society this winter. I find the grouping of the (perhaps) 550 species of the Carex in one list, a
puzzling thing. I have not affected to arrive at anything like natural grouping in the list of the British North
American species, but have availed myself of some simple characters, to throw them into as reasonable a
succession as I could. In a note at the beginning, I have made a reference to the principal works to be
consulted j but for the sake of brevity, I have not quoted, under each species, all these works. For instance,
I have not referred to any author beyond the one who first described the species ; and, therefore, you will
not find Willdenow nor Kunth quoted, except in those cases where it was essential. Had I done so, it
would have swelled the paper to an inconvenient size. I have quoted Schkuhr’s admirable figures, giving
the numbers of the fig. and not the lettering.
" To do honour to the intrepid men who have so. much exalted the character of our race by their arctic
voyages, I have called the new species generally after them, including the name of Dr Richardson’s gallant
though humble friend, Hepburn; you will find it necessary, therefore, to change a few of the names I
have affixed to the specimens forwarded to you by Hiinneman. C.Juscicolor is C. Liddoni ƒ C. varia, var.
from North America and the Rocky Mountains, is C. IHossi; C. Integra is C. Hoppneri. I cannot find
any authority for admitting C. squamosa and C. spargantoides as natives of British America.”
