I believe that the curious appearance of this Carex is due to 
gall influence, having in mind a gall described by Connold 
( Plant Galls of Britain, 1909, 90) on Carex vulpina, where 
“ sixteen galled “ leaflets ” (glumes) are clustered in a cone- 
like mass. Each “ leaflet ” contains but one larva, which 
pupates in the gall.” The gall-producer is unknown. The 
spikes of Mr. Wallace’s plant are similar. — J. E. Lousley. 
Is C. disticha Huds. with unusually large and strongly ribbed 
perigynia. — H. W\ Pugsley. This is C. disticlia Huds., as is 
shown by the utricles, which lack the broad wing of C. arenaria 
on the upper two-thirds. Of C. disticha, Butcher (“ Further 
Illustrations ”) remarks Often with large abortive utricles.” 
In the present plant some utricles measure 6 rums., the normal 
being 5 mm. Is this due to a gall? Perhaps Mr. E. W. 
Swanton, Haslemere, could say. A similar deformation may 
sometimes be seen in C. vulpina. — J. E. Little. 
I agree with Mr. Little, the utricles lack the broad wing of 
arenaria ; though I had told Mr. Wallace it was a very tall 
form of arenaria. — H. S. Thompson. 
Later. — Mr. Little sent the plant to Mr. G. M. Ash, asking 
him to show it to Mr. Swanton of the Haslemere Museum. 
Mr. Ash agrees that it is C. disticha, and reported that “ The 
fruits are attacked by a fly, species unknown. Similar galling 
of fruits of C. vulpina is said to be caused by Perrisia 
muricatae Meade,” and adds, “Mr. Swanton found a grub, 
orange in colour, in each fruit he opened. I consulted his 
French book on Galls, and notice that the fly Perrisia muricatae 
(as we might expect from the name) attacks C. muricata, as 
well as C. vulpina ; and Mr. Swanton thinks it quite possible 
that C. disticha is attacked by the same fly.” — G. M. Ash. 
Carex Leersii F. Schultz ( C . pseudo -divulsa Syme). Lane 
near Axbriclge, N. Somerset, July 2, 1930. — H. S. Thompson. 
The utricle exceeds the glume, and is narrowed at the base ; 
the nut is 3 mm. long and 1.5 mm. broad. Do not these 
characters indicate C. divulsa ? “ Nux quadrata ” is an 
important character for C. Leersii. — J. E. Little. Both 
plants grow in that lane, but I was uncertain of this gathering. 
— H. S. T. Probably correctly named, but the specimens, 
although quite young, appear to have withered before they 
were collected. — H. W. Pugsley. 
Carex Lachenalii Schkuhr. Come Sneachda, Cairngorm,
