Fes. 1910.] BOTANICAL SOCIETY OF EDINBURGH if 
the summit, at a height of nearly 13,000 feet, I noticed 
occasionally a small composite flower. 
I stayed for a few days at Puente del Inca, on the 
Argentine side of the Andes, to examine the plants in this 
neighbourhood, at a height of 9000 feet. Among the 
Species most conspicuous were T'ropcwolwm polyphyllum, 
a Berberis, and species of Adesmia. I also found a small 
Calceolaria and many of the Compositee. 
At Mendoza, we left the Transandine railway, and, 
crossing the great plains of the Argentine, sailed for 
Liverpool from Buenos Aires, thus completing a most 
interesting visit to the New World. 
THE GENUS CAREX IN Britain. By ARTHUR BENNETT, 
ELS. 
In the “Annals of Scottish Natural History,’ January 
1910, pp. 46-52, is a paper entitled “ Critical Remarks upon 
the Cyperacece-Caricordec as treated in ‘ Das Pflanzenreich ’ 
by G. Kiikenthal, 1909, Leipzig,” by Mr. G. C. Druce. 
In the following notes I have to some extent followed 
the above “remarks,” amplifying them in some cases. I 
have done so because my name happens to be mentioned 
here and there. 
I have not seen this part of the “ Pflanzenreich,” so 
cannot say to what extent the author recognises his in- 
debtedness to my late friend Mr. C. B. Clarke of Kew; but 
having often talked matters over with Mr. Clarke, and 
seeing many MSS. of the author, I know how much he owed 
to Mr. Clarke. 
I have given the original descriptions of some varieties 
named that do not appear in British floras. 
Carex binervis, Sm., var. alpina, Drejer (1), No. 52. 
CU. Sadleri, Linton. 
C. binervis, var. nigrescens, Druce. 
C. frigida, Syme, non All. 
“8 alpina humilior spicis paullo brevioribus Facré ad 
Quivig! Lyngbye. Hujus plantz modo 2 frustula male 
conservata in herbaria nostra deposuit Lyngbye, que tamen 
satis luenlenter probant, plantam hujus florze civem esse.”
