New to the district. Plentiful in a field of sown fodder on the 

 Tyntestield estate near Wraxall, June 1913. A few plants still on the 

 horder of the field, 1915. Mr. Bucknall and I could find the split 

 palea only in florets with immature or abortive fruit.

 Plentiful on a corn-sifting plot to the south of St. Plulip's, 1910! 

 The awnless form {arvense With.) is doubly starred in Druce's list of 

 St. Philip's Marsh aliens, but was recorded then.'e in Fl. Brist.

L. dilatata Presl. On a large plant of this fern in Glen Frome, 

 G., the growth of every frond had been arrested half way by the 

 attack of a dipterous insect (^Antliomi/ia signafa Brischke) ; the 

 upper half of the frond was condensed into a solid mass containing 

 the grub. Although all the fronds of this plant were affected, not 

 one of those growing alongside had been touched. 1 hear from 

 Miss Koper that she noticed this malformation at the same spot seven 

 years earlier. 



Asph'nii(in JanceoJatum Huds. My trust that this might still 

 exist in some other pai'ts of Glen Frome (^Fl. Brlsf. p. 685) has 

 been justified. In June 1914, Mr. W. H. PuUin showed me two 

 spots on precipitous sandstone rock above the river, in one of which 

 there grew at least twenty plants. In 191G he discovered another, in 

 a still more inaccessible place, where the fern is even finer. 



Geterach nfficinnrum Willd. Bifid or trifid fronds, so frequent 

 on plants of Scolopendrium , are in my experience extremely rare with 

 this fern. Miss Lee, of Bristol University, has lately found both 

 variations on a wall at Kelston, S. My statement in Fl. Brisf. that 

 Geterach is unknown in Middlesex was based on Fl. Midd. 341. 

 1 learn from Mr. C. B. Green, of Swanage, that during his residence 

 in Middlesex he became aware of at least four stations for the fern in 

 that county, in one of which it was fairly plentiful. — var. crenatnin

Ljicopodium ^elaqo L. Three or four })l:ints were discovered on 

 Black'down, Mendi]),'at the end of March 1915 by Mrs. Sandwith. 

 1 saw three in May. The next year about twenty were found on 

 another part of the warren by Miss Koper. Some of these had been 

 badly scorched by a heath-fire.
