which Mr. Pugsley, as a member of the Technical Sub- 
committee of the Wild Plant Conservation Board, has had so 
large a hand. And particularly the suggestive and useful 
pamphlet No. 31 on The Protection of Wild Flowers, which 
should have a vide circulation. Copies of the latter may be 
had at 1 \d. each from the above address. They should be of 
special value to school teachers. 
Report 1932-33, p. 191 ; Carex silvatica Hudson. (Utricles). 
Folly Alder Swamp, Hitcbin, July 4, 1928. Mr. Little wrote 
last June : “ Owing to a much regretted mistake about 6 
packets of the C. helodes [984] which follows it in the Report, 
were included under the total number of 16 packets. I have 
to thank Mr. J. Fraser for pointing out that his packet was 
C. helodes. The differences in the utricles are : — C. silvatica : 
green, turning rusty, 5 mm. long, nerveless or obscurely 
nerved, suddenly narrowed into a long beak which is smooth 
or nearly so. C. helodes : green, ovoid-trigonous, 5 mm. long, 
having 3-6 nerves on the two faces, more gradually narrowed 
into a relatively shorter beak, which is (under a lens) more 
scabrid at the edge. In silvatica the beak occupies a longer 
proportion of the total length. C. helodes has never been 
recorded for Herts.” — J. E. Little. 
Last Report : Corrections. 
P. 169, last line but three. — ( Diplotaxis ). The intention 
was : — 
Pod, with stipe and style up to 34 mm. Pedicel up to 22 mm. 
or Pod, with stipe and style 32 mm. Pedicel 20 mm. 
Stipe 1-0 mm. 
i.e., the second line was alternative to the first, for a shorter 
pod ; in the same way that 2 measurements were given for 
D. muralis var. — J. E. Little. 
P. 177, 12 lines from bottom. — For indivises read indivises. 
P. 186, line 7. — For sans read sous. 
P. 187. — For D. H. Danser (tivice) read B. H. Danser. 
P. 191. — C. silvatica utricles, see note above. 
The editor was disappointed to find that last year’s Report 
was pinned instead of being sewn, even though our good 
printers did so in the interests of speed and hence cost.
