MACKENZIE: NOTES ON CAREX—XIII 349 
The only other European species of Carex to which the de- 
scription and figure of Allioni could apply is Carex Heleonastes L. 
f., and this species is not involved. It is difficult, indeed, to 
understand how Holm after carefully giving the above facts 
should write, ‘“we regret to say that we have not succeeded in 
determining the identity of this second species of Allioni with 
absolute certainty.’’ One would say that the evidence is much 
more complete than with a great number of names in use. 
4. NEW NAMES 
“Kobresia simpliciuscula (Wahlenb.) Mackenzie, comb. nov. 
Carex peor Wahlenb. Vet.-Akad. Nya Handl. Stock- 
holm 141. 
Kobresia caricina Willd. Sp. Pl. 4: 206. 1805. 
It is curious that the above combination does not seem to 
have been made. In the Pflanzenreich (4"°: 45) Kiikenthal refers 
the name Carex simpliciuscula to Kobresia with a question mark 
and adds ‘‘fide A. Bennett.’’ However, when it came to ex- 
cluding the species from Carex all doubt disappeared, and on 
page 765 the two plants are treated as identical without question. 
What Bennett really says (Jour. Bot. 35: 263. 1897) is as 
follows: 
In Vet. Ak. Handl. 141 (1803) (Act. Holm) Wahlenberg describes a 
Carex simpliciuscula from ‘Westmoreland, Anglia.’ Sprengel puts this to 
Kobresia caricina Willd. and Kunth quotes Sprengel; by the kindness of Dr. 
Almquist I am able to say this is correct, as he has examined the specimen for 
me in the Herb. Vet. Ak. Stockholm 
The correct name for the Kobresia would seem to be entirely 
clear. 
“Carex hirsutella Mackenzie, nom. nov. 
Carex hirsuta Willd. Sp. Pl. 4: 252. 1805. Not C. hirsuta 
Suter., 1802. 
Carex triceps Michx. var. hirsuta Bailey, Mem. Torrey Club 1: 
35. 1889. 
5. A CALCIPHILE SEDGE CLOSELY ALLIED TO A NON-CALCIPHILE 
SPECIES 
Carex Muhlenbergii Schkuhr is usually a plant of very sterile 
sandy wastes. It is found from Maine to Florida and in the
