Jury 1910.} BOTANICAL SOCIETY OF EDINBURGH 87 
specimens from Wahlenberg in Boott’s herbarium at Kew 
show. 
The first record of aguatilis as a Scottish plant was in 
“Eng. Botany,” suppl. t. 2758 (1832): “ Found on the Clova 
range of mountains by W. J. Hooker, W. 8S. Burchell, and 
R. K. Greville” (about 1824). 
The description was by Dr. Greville, and I have specimens 
gathered by him in 1831. In Hooker’s “ Brit. Flora” (1830), 
p. 398, it appears as C. rigida, Good., var. 8. In the 3rd 
ed. (1842), 427, he quotes Boott’s doubts as to its being the 
plant intended by Wahlenberg; but now no doubt is felt, 
and I have myself seen specimens named by Wahlenberg. 
In the year 1851 Mr. J. M‘Laren read a paper, “ Remarks 
on some British Carices,” before this Society, which was also 
published in the “ Botanical Gazette,” 11. (1851), pp. 17-27. 
In this he suggests three varieties of C. aquatilis, but 
gives them no names. His y is the nearest we possess to 
the type plant of Wahlenberg; the habitat he gives is 
“Glen Isla, and by the bridge at Clova.” His 8 is the 
Clova tableland plant, and his a comes in between them. 
This Carex is now known from twenty-three Scottish 
counties, ten Irish counties, two English counties, and one 
Welsh county. Yet, in 1860, Hooker and Arnott, in their 
“ British Flora,” give only the stations of “the Clova table- 
land, and in the valley by the bridge at Clova.” 
One of the most interesting facts with regard to its dis- 
tribution in Britain is its occurrence in Wales, and Kerry in 
Treland, at low levels; yet it is not on record for either 
Denmark or North Germany. In one of its forms ((. stans, 
Drejer) it extends in Greenland north to 72° N. lat. In 
Finland it occurs in both Finnish and Russian Lapland to 
68° N. lat., and to Nova Zemblia. 
Though I have tried, it seems impossible to specifically 
separate our lowland plants from the high northern forms. 
In the “Journal of Botany” for June and July 1897, I 
gave five forms as occurring in Scotland :— 
var. cuspidata, Leestad, 
» virescens, Anders. 
» minor, Boott. 
elatior, Bab. 
» epigejos, Lest. non Fries.
