Antennaria dioica. St. Brody's record of this plant is 
correct. It occurs in very small quantity, and is difficult to 
find, but Mrs. Gregory has seen it twice on Brean Down, and 
she discovered some also on Worle Hill, Weston-super-Mare, 
whence I had from her a specimen. 
Garduus arvensis Curt. var. B. setosus (Suffl. Notes, 1886). 
This distinct-looking variety which has been known many 
years on the right bank of the Avon, below Bath, is now 
determined to be Girsium arvense Scop. var. obtusilobmn, f. 
suhincanum G. Beck, Fl. N.Q. p. 1239, Koch, Syn. ed. iii. 
p. 1553 [Journ. Bot. 1901, p. 91). We have gathered on 
dust-heaps on the other side of the river a form with leaves 
glabrous beneath, which is the f. suhviride G. Beck. 
Crefis biennis, first observed in the district by Kev. E. P. 
Murray, appears to be spreading at his locahty, where I now 
find it in three fields. Mrs. Gregory has it a^so at Weston- 
super-Mare and at Winscombe. C. nicceensis was noted too 
near Axbridge by Mr. Murray. A specimen of C. foetida 
in the Jenyns herbarium is labelled " Bathampton, July 9, 
1867 ; G. E. Broomer 
Hieracium. The aspect of this genus has been entirely 
altered of late years by the critical industry of our leading 
botanists, who have differentiated and defined many new 
forms, and in doing so have necessarily subdivided and split 
up the old groups. For example, the Cheddar " murorum " 
certainly comprised three distinct plants, now known as 
H. Schmidtii Tausch., H. stenohfis Lindeb., and H. Lima 
F. J. Hanbury. The hawkweed abundant on limestone 
about CHfton and Bristol, and formerly named vulgatum,, is 
not that type, but is determined to be H. sciaphilmn Uechtr. 
The " H. gothicum " on Ebbor rocks gathered by Professor 
Babington in 1851 {Flora of Somerset, p. 209), is considered, 
on examination of fresh specimens, to belong to H. rigidum 
var. fullatum. Mr. Bucknall has found the same form on 
Churchill Batch, In Journ. Bot. 1899, p. 418, we referred
